Benefits of native Android app development
ACCESS TO MORE USERS
Android is the most popular mobile software. It owned around 73% of mobile OS market share in 2020, according to StatCounter. So, if you want to reach as many users as possible with one native app, Android might be the best option.
FAST PERFORMANCE
Native Android apps can have many features that rely on the system components and still work smoothly. NFC, Bluetooth, camera – those are just a few examples of such functions. They can slow down the app, unless you choose a native technology.
DEDICATED UI DESIGN
Users who have native apps can enjoy an interface designed specifically with Android devices in mind. It makes it easier for them to navigate within the app and discover new options. This way you increase the chances for conversions.
Kotlin - a language for Android OS
We build our native Android apps with Kotlin. It’s a programming language recommended by Google.
Kotlin allows us to quickly make even complex apps, with multiple features based on the system components. It reduces the risk of bugs and errors, so it’s the best choice when it comes to efficient mobile app development for Android.
Kotlin is compatible with Java. This means that if you have an app written with this programming language, our Android developers can still add Kotlin components.
Why choose our Android development company?
Our Android developers have from 4 up to 12 years of experience. So, rest assured – your app will be prepared by people who have multiple products in their portfolio. They know how to make well-performing software for mobile devices.
It’s better to be safe than sorry, so we don’t rely solely on developers’ skills. We also provide you with quality assurance services. Our QA specialists meticulously test every app and check if it works seamlessly.
A dedicated project manager makes sure everything goes according to plan. Alternatively, our software engineer takes up a role of a technical project coordinator and supervises the development process.
On top of that, we prepare UX/UI designs if needed and run the Product Design workshops to help you find the best solutions. Our Android app development company is based in Poland but we organize both on-site and online workshops.
During the Android development process, you are always kept in the loop. We regularly present the results of our work and inform you about the latest updates.

Android app development stages
Our goal is to provide the best UX and create Android applications that bring measurable values to our clients. We achieve this with the mobile app development process we’ve mastered over the years.
1
Kickoff & Preparations
We begin with a series of meetings with a client. At this early stage, we set up the goals of a project, determine the general requirements, and core features. Everyone gets to know each others’ roles and we choose the communication model. Once we have a Minimal Viable Product strategy, we estimate the costs, and plan next actions. Later, our Android developers choose the technologies and tools needed to complete the project and identify potential challenges. Then the whole team starts preparing the backlog.
2
Design
It’s an optional stage – if we are responsible for the UX/UI design, we prepare it based on a research on potential users and the competition. We also use such tools, as persona profiles and wireframes, among others.
3
Development & testing
Our Android mobile app development process is based on Agile methodologies and breaks down into iterations (sprints). The result of every iteration is the application that gets tested by a QA specialist. During this stage, we’re in touch with the client and regularly show the outcomes of our work. Our team meets every day to discuss the progress and make sure we’re heading in the right direction. We also organize retrospective meetings to find out what went well and what still needs to be improved.
4
Product release
We supervise the release process and adjust the product to requirements of the Google Play store. This includes informing the client what legal and marketing materials are needed. Our task here is also to advice client on how to prepare the app’s page according to ASO factors.
5
Maintenance
It’s a second part of the development stage that takes place after each product release. This is when our Android app developers add new components, make improvements, and ensure the stability of the app. When the new version is finished, we return to the Product Release phase and launch it on Google Play.
Android m-commerce app for a fashion store
Answear
We’ve made this native Android application for an online store with products from over 400 brands. Answear sells clothes, shoes and accessories in 11 countries, so we had to adjust the app to each market.
Our goal was to create an app that shortens the distance between a user and the brand. We also wanted to make shopping online easier.
The outcome of this project was more than satisfactory. The average value of a shopping cart is 30% higher in the mobile app, compared to the web app.

Native Android app, Flutter, or KMP?
If you want to reach both Android and iOS users but your budget is limited, maybe you should consider a cross-platform technology such as Flutter or Kotlin Multiplatform. This way you can build just one app and get access to more clients. Before you make the decision, tell us about your project and make sure if a cross-platform solution is recommended in your case.
