iOS and Android app development, from first version to the app stores.
We build your app from a single Flutter codebase for iOS and Android, and handle the whole process: the backend, App Store and Google Play account setup, store review, launch and maintenance afterwards.
Every project gets its own quote, and the fixed price is set in writing before any work starts.
Everything in one hand,
from the first sketch to every update.
Design and development
We start by planning the features, the user experience and the design. The iOS and Android versions share one codebase, so development is faster, maintenance is simpler and you get the same premium quality on both platforms.
A finished app for iOS and Android
Backend
We build the backend behind your iOS and Android app too: secure sign-in, database, payments and subscriptions, push notifications. On Supabase or Firebase, or as a custom-built backend, so it stays fast and reliable as your user base grows.
A reliable backend in your own accounts
Store release
We publish the app from App Store and Google Play accounts registered in your name. We create the store listing and screenshots, fill in the privacy details, and see the app through store review until it is available to download.
Downloadable on the App Store and Google Play
Maintenance
We keep looking after the app after launch: we prepare it for new iOS and Android versions, keep up with store rule changes and, on request, extend it with new features.

Common questions
about mobile apps
Why do we build in Flutter?
The iPhone and Android versions share one codebase. Development is faster, maintenance is simpler and the quality is the same on both platforms, while the app runs at native speed. Flutter is one of the two most widely used cross-platform frameworks, alongside React Native.1 If an app relies on special iOS or Android features, we point that out in the plan.
Whose name are the App Store and Google Play accounts in?
Yours, or your company's. That is whose name the developer accounts are created in, and the source code goes into your own GitHub account, so every part of the app is yours.
How long until the app is in the stores?
Apple usually reviews a finished app in 1–2 days: 90% of submissions are reviewed within 48 hours.2 On Google Play an organisation account can publish right away, while a personal account first needs a 14-day closed test with at least 12 testers.3 The schedule for the build itself is in the detailed plan, split into milestones.
What if the App Store or Google Play rejects the app?
It happens, and we handle it. We find out why the app was rejected, make the changes needed and resubmit it until it is live. This is part of the store release, not an extra service.
What does an app cost to run after launch?
In our experience, plan for roughly 10 to 20% of the build cost per year. That covers the yearly SDK updates the stores require: Apple wants the iOS 27 SDK from April 2027, and Google Play has required Android 16 since 31 August 2026.45 Your written quote fixes the maintenance fee.
Do you build the backend behind the app too?
Yes, we build both the app and its backend, so everything is in one hand. That covers sign-in, the database, payments and subscriptions, and push notifications. Depending on your needs we build on Supabase or Firebase, or a custom backend, and everything runs in your own accounts.
