iOS and Android mobile app development
I design and build native mobile apps for iOS and Android — from idea and interface, through code, to release on the App Store and Google Play. My focus is on apps that are fast, stable and genuinely useful, not just good-looking in screenshots.
I run the app project from the first conversation to launch and post-release support. I build natively — Swift on iOS, Kotlin on Android — so the app runs smoothly and has full access to the phone's capabilities. When the budget is tight, we start with an MVP and grow it in stages.
Native: iOS (Swift) and Android (Kotlin)
I build apps natively, in the languages and tools recommended by Apple and Google — Swift and Kotlin. Native code means smooth performance, fast startup, access to the camera, push notifications, location and other phone features, and compliance with both stores' guidelines. I design the interface to match each platform's standards — an iPhone app should feel different from an Android one, and users notice when it doesn't.
From MVP to the full version
Not every idea needs to be built in full right away. Often it's best to start with an MVP — a version with the core features that you can put in front of users and investors, gather feedback, and only then expand. That start is cheaper and less risky: you test whether the idea holds up before committing the full budget. We define the MVP scope together, so the starter version is complete but not overloaded.
Publishing to the App Store and Google Play
I handle the whole release process: developer accounts, icons, screenshots and descriptions, configuration in App Store Connect and Google Play Console, and getting through both stores' review. After launch an app needs maintenance — updates for new OS versions, fixes and new features — and I can take that on too, so the app doesn't break after the next iOS or Android update.
Frequently asked questions
- How much does it cost to build a mobile app?
- A native app for one platform starts from 9,900 PLN, two apps (iOS and Android) in one project from 17,900 PLN, and an MVP version from 15,000 PLN. The final price depends on the number and complexity of features — I prepare a quote after discussing the scope.
- Do you build for iOS or Android?
- Both. I can build an app for iOS only, Android only, or both versions within one project. The choice usually comes down to where your users are and your budget.
- What is an MVP and is it worth starting with one?
- An MVP is a starter version of the app with the most important features. It's worth starting there when you want to test the idea with real users faster and cheaper before investing in the full version. Based on their reactions, we develop the app further.
- Will you help publish the app to the stores?
- Yes. I handle preparing the assets, configuring developer accounts and publishing to the App Store and Google Play, including getting through both stores' review.
- What happens after the app is released?
- Apps need maintenance — updates for new iOS and Android versions, bug fixes and new features. I can take care of that as part of ongoing cooperation, so the app keeps running without interruptions.
