Our services
Mobile App Development for Android and iOS
Android and iOS apps from one Flutter codebase: design, back end, subscriptions, notifications and Google Play launch. Nine of our apps are live.
The first question people ask before building a mobile app is: “Will it actually end up in the store?” Our answer comes with examples: nine apps we publish under our own name on Google Play — real-time multiplayer games, education apps and utilities.
We build Android and iOS from a single Flutter codebase, so you do not pay for two separate apps. Offline mode, push notifications, in-app purchases and subscriptions (Adapty), pre-produced professional voice-over and app store optimisation (ASO) included.

Frequently asked questions
How long does it take to build a mobile app?
A lean app reaches the store in 4–8 weeks; an app with user accounts, payments and an admin panel in 2–4 months. The exact timeline is written into the quote.
Flutter or native development?
For most apps Flutter is faster and more economical with one codebase. Where an app depends heavily on device hardware, we add native modules.
