STAGE 1. Choosing a partner – select a company to design and develop your app
Decide if you want to build your app in-house, or outsource its development. This article may help you: Inhouse vs. outsourcing software development. If you decide to outsource your product creation, you need to know how to choose a proper app development company for your project. How to verify if a company you want to choose, is trustworthy? We recommend you to:
- Use Clutch.co or other platforms for B2B buying
Clutch.co, AppFutura, GoodFirms, ContractIQ – use platforms that will help you to make an initial selection of companies that meet your requirements.
- Analyze pre-selected companies
Check opinions about them, as well as their portfolio. Ask questions like:
- Do they have experience in creating products similar to yours?
- Did they work with partners from many countries and different industries?
- Do they work with start-ups, big companies… or both?
- Do they use new solutions and technology?
- Analyze the estimations you receive
It is worth to get estimations from more than one company and compare them. If you get two totally different estimations, it is worth checking how each team made their respective figure.
- Did you deliver the same information and documentation to both companies?
- Ask the companies on which assumptions they based their forecasts. Does the lower estimation contain all the crucial elements included in the higher one?
- Did they ask questions to learn more about your app idea?
- Does the estimation contain the time for team meetings?
- Does the estimation contain the time for Quality Assurance (e.g. writing tests)?
- Did the companies take into account the risk of unforeseen events?
- If your app’s design demands some non-native solutions, is this considered in the estimation?
- If your product is a typical kind of app, like e-commerce or m-commerce, but you want it to have some untypical features, check if they have been considered in the Estimations.

- Make sure the code will be written in English
- Make sure the code will be hosted on Code Repositories Hosts
E.g. Bitbucket, GitHub, so you can have access to the code and be sure that it is safely stored.
- Verify the Independent Contract Agreement
Verify the contract you get carefully and make sure to consult with a lawyer about it. Below, we’ve listed for you a few important elements that should be included in a contract. We are not writing about some obvious elements, like personal data of parties, but rather factors more specific to software houses.
- Confidentiality: Make sure that the contract contains a clause about confidential information. Your partner should commit himself or herself to not disclosing any information about your project that is not public yet. –> Download for Free your Printable NDA (PDF)
- Intellectual property: You should have the rights to everything the software house produces. The contractor shall execute and deliver such further instrument(s) and take such action(s) as may reasonably be required to complete the assignment of intellectual property rights in the Deliverables to Company’s sole and exclusive ownership.
- Choice of Law: The contract should indicate a dispute resolution place. That is especially important if the software house is from another country. Probably, your partner will want to choose the judiciary of his country. We would recommend compromising and choose the laws of another country, with the jurisdiction you know, e.g. the United Kingdom.
- Advance payment: We recommend that the advance payment should not exceed the cost of the team’s work for one month. In case a contractor must incur significant expenditure (e.g. for hardware or licenses) at the beginning of the project, a higher advance payment can be reasonable.
- Payment deadline: The contract should regulate the consequences of delays in payments. What is the acceptable delay? After how many days will interest be charged? After how many days can the development team stop work? Contrary to appearances, such a clause secures you.
- Conditions for terminating the contract: It is safe to set a notice period of about 15-20 days.
- Time & Material – in this type of contract, there is no need to specify an exact deadline. You decide when the app is ready. Your Feedback after each iteration is implemented up to date.
- Fixed Price – the contract contains a schedule of partial deliverables. What is more, it is worth setting the time for you to give feedback for every iteration, as well as for the team for implementing that feedback.

Let’s sum up Stage 1 of the mobile app development process:
STAGE 2. Product Discovery – define what you want to create, for who and why
Before you start your mobile app development process, it’s necessary to clarify your app’s vision – we call this phase Product Discovery. This is the key to your app’s success. The foundation of Product Discovery is a constant testing of solutions and ideas, as well as learning how to adapt them to the user’s needs. It also ensures that not only you are aware of the end-users’ needs, but your development team knows your goals and is able to deliver your ideas.
Here are the following areas you should focus on during Product Discovery:
- Establishing a strategy. What is your goal? What outcome do you want to achieve?
- Targeting potential users and their problem. Who is the user? What kind of problems do they have? How can we help them?
- Ideating solutions. How can you solve the problem? What will be the outcome of such a solution? What is the best solution?
- Prototyping. What is my user’s experience? Do I like the solution?
- Reviewing ideas. Are your ideas good enough? What do my users think about them? Can I really solve their problems?
- Narrowing down the solutions. Which ideas are we going to implement?
- Prioritization. Which features are the most crucial in the app? What are the features to be implemented first?
- Planning. What is the scope of our MVP (Minimum Viable Product)? How can I measure the end result to determine if the goal has been met?
In this article, you can read more detailed description of each of the above-mentioned Product Discovery elements.
You can find the answers by yourself, with your team, or during a Product Design Workshop organized by an outside app development company – it’s your choice.
The recommended tools that can help you to clarify the idea of your app are Product Canvas (PDF print), Personas (PDF print), Event Storming, User Journey Map, and Prioritization Chart (PDF print). You can find a description of all of these tools in this article: Mobile App Development Process – Stage 2. Product Discovery.
If you already know the answers, and your vision is clear, this is great! Yet it’s simply not enough to have them in your mind. Write them down and confront them with others – talk to people from your team, employees, or just your friends. They should understand what it is about.
How about starting development without clarifying your vision? Product Discovery is an optional process but would it make sense to start costly development without thorough research? In the Theory of Quality Management, we have the “1:10:100 rule”, which states that prevention is cheaper than correction, and correction is cheaper than failure. Product Discovery costs you nothing compared to releasing a useless application.
In short, Product Discovery is the app development phase where we are focused on building the right thing, as opposed to building the thing right.

Let’s sum up Stage 2 of mobile app development process::
STAGE 3. UX / UI app design – determine how your app will work and look
Let’s start with an explanation, what do UX and UI mean. To put it simply: UX (User Experience) is how an app works UI (User Interface) is how it looks. Well designed UX and UI are very important from a business point of view. At the end of the day, they influence the retention rate. If your apps’ user experience will be enjoyable and flawless, and the design of the app will create a positive impression on its users, they will love it, and use it.
This stage of mobile app development process includes creating:
User Journey Map
You (alone or with your development team) create a User Journey Map. It is a visualization of the user flow through your app. It tells the story of the user’s experience. At Droids On Roids, User Journey Map takes the form of the drawn schema on the wall (we wrote about it here), or we draw it using Figma. It is usually a part of Project Discovery, but we present it here to show you that is crucial to create wireframes and user interfaces.
Designers create Wireframes – digital, simplified visual concepts of the future app. They lay out the structure, hierarchy, and relationship between the elements that make up the product. It is a kind of app’s backbone.
Then, designers use Wireframes to create a Clickable Prototype – a dynamic, interactive model of your app. It simulates a real-world product. An example of a Clickable Prototype:
Designers work on the visual language of your app, its style guide, User Interface, and motion design. You get mockups showing the final look of your app, and videos presenting motion design (animations & screen transitions) in your app.
To sum up, even if your app idea is great, but its interface and UX design will be of low quality, you won’t succeed. Make sure that the UX and UI Design processes run in a thoughtful way. Be engaged in each stage of designing your product, so the team can shape the final designs according to your expectations. And last, but not least – remember to put your app’s users in the center of your thinking.
STAGE 4. Project kick-off & setup – last preparations before the start of app development
App Development Kick-off has a significant influence on the successful cooperation with your software partner. In short, it’s time to define your role as a Product Owner and to clarify every role in the team. What is more, Project Kick-off means also setting the rules you want to follow, and planning the next steps. Kick-off may have different forms, at Droids On Roids we organize a Kick-off meeting with every client (remote, or face-to-face), it takes around 2 hours. An example of how kick-off may look:
When App Development Kick-off is completed, the first Sprint starts. It is also the moment when developers set up your project.
How do the developers set up your project?
These 6 elements are specific for mobile app development, but in the case of web apps, they look similar (with the exception of the third point).
- Creating a repository for a project at GitHub or another web-based hosting service. It means creating a space dedicated to your project on the cloud-hosted platform, where all versions of your code will be safely kept and archived.
- Continuous Integration setup. Every new piece of code has to be checked before it is merged into the project. It’s checked manually, but also with automated tests run by special platforms like Bitrise, CircleCI, or Jenkins. The process of automating the build and testing the code every time a team member commits changes is called Continous Integration. The second role of CI platforms is pushing the app versions to Google Play / Apple Store and allowing running tests by users. At Droids On Roids, we use Bitrise.
- Setup of the beta distribution tool on the CI platform. App Center, Fabric – these are a few examples of tools that help you to collect live crash reports, get feedback from your app’s users, or distribute your betas. To say simply – they take care of the quality of your product.
- Choosing a code architecture, libraries & SDKs. Developers choose the code architecture for your project (e.g. MVP, MVVP, VIPER, MVC, Clean Swift). Code architecture can be compared to the construction of a building. It is not visible outside when the building is finished, but it decides about the shape of the object and its’ solidity.
- What is more, developers choose also libraries & SDKs (Software Development Kits) which they will use in your project. In other words, SDK is a set of software development tools useful in app development. Read also: Pros and Cons of Using Third-Party Software in Your App Development.
- Setup project in IDE (Integrated Development Environment). Developers set up your project in a program that they will use to write the code – e.g. Android Studio for Android Apps, or XCode for iOS Apps. To the program, they add also outside SDKs or libraries that will help them to optimize their work.
- Register the app in Google Play Console, Firebase API Console, and other services if needed. If your app will use some third-party party components (e.g. Google Maps, push notifications), it must be registered on the suppliers’ services.

Let’s sum up Stage 4 of the mobile app development process::
STAGE 5. App development with Quality Assurance
That’s the phase, where developers start to write the code and produce your product. How do they do that? Mobile app development is an iterative process. You have probably heard the term Sprints or Scrum. This basically means that you break up all development work into smaller milestones and develop your mobile app in a series of cycles. Each cycle will include refinement, planning, development, testing, review, and retrospective.
Sprint Refinement (Product Backlog Refinement) is the act of keeping the backlog updated, clean, and ordered. A backlog is an ordered list of everything that is known to be needed in the product. Refinement should be an ongoing process. However, it is useful to have a planned meeting for Refinement.
For example at Droids On Roids, we discuss the tasks from the top of the Product Backlog, making sure that their acceptance criteria are clear, and estimating them. Then, during the Planning Meeting, there is less to review, and planning is easier.
Only the first Sprint starts with Refinement – we need to prepare backlog before the first Planning. Later, every Sprint will start with the Planning meeting.
Sprint Planning is max. 2 hours meeting (for 1-week Sprint). Its’ goal is to decide which tasks should be included in the upcoming Sprint. The team talks about the things to do, making sure that the acceptance criteria for each task are clear and accepted by everyone. The Product Owner (you) joins this meeting (for example on Skype) so he or she takes part actively in planning the next iteration.
Developers are writing the code and implementing the features planned for the Sprint, QA Engineers are writing automated tests. It’s good when developers practice Code Review. Code Review is not necessary for developing a crash-free app but it is a good practice if you want your app to have code written in a clear and transparent way, so in the future other developers can easily improve the app and continue working on the code.
During development, we use a platform called AppCenter. It allows us to privately and securely distribute the in-development version of the app to testers, clients, and other developers. The platform automatically notifies users of new builds (so everyone is testing the latest version), provides crash reporting and ensures only approved testers have access to your app.
Quality Assurance (or simply QA) is a way of preventing mistakes in developed applications and avoiding problems when delivering them to users. It is integrated into every stage of development. This is an example of how Quality Assurance can be integrated into the app development process:
- Coding – developer writes the code, QA specialist writes automated tests.
- Pull Request – developer tells others about a new part of the code.
- Execution of automated tests – automatic tests that check whether new changes didn’t break any already implemented functionalities. It consists of:
- Static Code Analysis – a code is checked by a special program (Lint, Sonar), which verifies if the code meets the good standards set by our development team.
- Executing Unit Tests – automated tests that validate if each unit of the software performs as designed.
- Executing UI Integration Tests – automated tests that check if the app components are correctly integrated.
- Virtual Device Testing – we use it to find crashes in Android apps. It simulates a real app user.
- Code Review – every piece of code written by one developer is approved at least by 1 another dev.
- Deployment – the latest alpha/beta release is delivered to the client and testers.
- Manual Tests – manual testing of the app based on specified use cases. Made by QA specialists.
- The feature is done
The process is repeated many times during development. Read also: Mobile Security Testing. Make the First Step!
Below you can find a list of good practices in Quality Assurance that we recommend you to consider while working with an outsourced development team:
- First, make sure that your partner has Quality Assurance engineers who will take care of the highest product quality at every development stage.
- The development team should have a dedicated specialist who will ensure QA for your project holistically. Why? He will have a map of the whole project in his mind. For work hygiene, pair-testing is fine, but frequent changes of testers carry the risk of mess and chaos in the project.
- You are not the one who should pick up basic errors and differences between what is in the requirements and what you got.
- Developers are not testers. Your partner says that they don’t have a Quality Assurance specialist, but it is OK because a developer will test the app? Well, not exactly. A developer who wrote the code shouldn’t check his own work. It is harder for an author to see their own mistakes. What is more, developers can consider something not as a mistake because they understand what they have written. An extra pair of eyes is always helpful.
- QA should be ensured from the very beginning. Don’t put QA off until later. Even small errors in the early stages of development can cause more complex complications in the future. The sooner you start with QA, the fewer troubles you will have in the future.
- You should have insight into the output of the tests. Which features have been tested so far? What bugs have been found? As an app owner, you should have insight into testing progress. There are many tools that can be used to easily track and follow the status of tests, e.g. Testlink, QA touch, TestRail, or Jira.
- The tests should be run on different types of devices because your product should work perfectly not only on one type of smartphone. A great solution is Smartphone Test Farm (STF) – it is an app that allows developers to:
- control and manage real-time testing on many devices remotely from their workplaces
- run automated tests using dedicated software like Bitrise that enables testing apps on many devices at once.
During the Sprint Review, the Scrum Team and stakeholders collaborate about what was done in the Sprint. A Sprint Review is held at the end of the Sprint to inspect the Increment (all tasks completed during the Sprint). It takes up to 1 hour in case of a 1-week Sprint. A great practice is if, after Review, your development team send you:
- An app demo build (so you can check if the created app fits your expectations)
- A detailed review of what’s been done
- Information about eventual difficulties or additional work that has been done
- Information about how many hours the team worked on the project during the Sprint
According to the PO’s preferences, he or she can take part in the Review meeting, or just get the above-mentioned information with an E-mail.
Retrospective meeting (about 45 m for 1-week Sprint) occurs usually after the Sprint Review. During this meeting, you and the team plan together ways to increase product quality by improving its’ work processes. The purpose of the Sprint Retrospective is to:
- Inspect how the last Sprint went with regards to people, relations, process, and tools
- See what went well and define potential improvements
- Create a plan for implementing improvements
Please read the whole article describing app development with Scrum – and learn Scrum Sprint Workflow with all Scrum events.
To sum up this stage – all features are firstly planed, then implemented and tested while the Continous Integrations process, where Quality Assurance is integrated at every step, in the end, they are accepted by the Product Owner. The entire application is built in this way – in repeated cycles – of planning, coding, and testing, reviewing, and improving the process and the product. This approach gives you great flexibility – it makes it easier for you to monitor the process, the product, and introduce changes easily.
STAGE 6. Preparation and publishing of the app on Google Play Store and Apple Store
When the first version of your mobile app is ready, it is time to publish it. Your partner should assist you to upload your Android app on the Google Play Store, and your iOS app on the Apple Store. It is also a part of the app development process. The company should guide you through the app setup on the stores regarding the marketing materials, description, and legacy issues.

- Download for free: App Publishing Checklist for Google Play (Printable PDF)
Then, developers upload the build of your app using Xcode. The app might then get tested using the TestFlight tool. The same build of the app that was tested can be then assigned to a specific version of your app. The next step is to upload screenshots of your app taken on different devices, fill in all the missing legal information, and submit the app for review. Apple employees will test your app and see whether it complies with the rules of the App Store. This might take around 2 days.
Read our step-by-step Guide on How to Publish your iOS App on the App Store.
STAGE 7. Post-development phase – app maintenance & further development
During app maintenance, the development team implements app monitoring tools (e.g. Crashlytics, Google Analytics, Firebase) to your product. Thanks to these tools team can detect any crashes, follow app’s statistics, and plan product enhancements. The post-development phase includes also further development of your product – it allows your app to stay attractive, adapt to changing market conditions, and users’ feedback.

Thanks for sharing.
i tried to make a chat app with react native.
hahhahahaha it broke. I looked at the “experienced community” and they couldn’t help.
it took me 3 weeks to get to where i was before it broke.
i tried flutter and in 3 days, i made a fully functioning chat app, working on iOS and android.
i was a c# dev so i consider that as an advantage: But i also had 1 year experience in js and it was still a pain in the ass to learn react
Awesome picture. Website design service in India.
Both React Native and Flutter have their pros and cons. But Flutter, surge ahead of the competition as it is a Dart based Framework with free SDK which is being backed up by Google too. Flutter, no doubt has all the capabilities to create robust and scalable mobile apps in no time.
Whereas, React Native supports few rich components and has a lot of libraries mostly of a low quality. And the major drawback is it is first translated into a native code and there is a no support for decimals. This could actually put you in a trouble for mobile apps that needs any kind of computation.
Thank you so much for giving you time and writing this for all of us. I provide App Development Service all over the world with company name DarkBears.com
I have a question what do you think which is the better SDK then flutter?

Thanks for sharing informative content. I am glad that I have found something new here worth adding to my favorites.
It is really a great mobile application backend development guide. It shows how important the backend is for any mobile app. It also shows that backend is one of the main aspect of the mobile app. Database, storage and user authentication are some of the major area where the developer need to work more compared to the UX-UI design and frontend development. The most what I like in this article is your image explanation where you show the tip of the mountain as the front-end, ui-ux and the base of the mountain which is not visible to eyes as it is in the sea as a backend development. It is very easy to understand the difference through this image.
Nah, it’s fine
