Flutter or React Native – which do you recommend?

We develop with Flutter; the Techlogia app is built with it too. Flutter fits especially well if the app should look the same on both platforms or needs a lot of animation. If your team has strong React experience and will maintain the app itself later, React Native can be the better choice – we work that out with you in the initial conversation.

What does the app cost after launch?

A developer account costs 99 US dollars a year at Apple and a one-time 25 US dollars at Google. Add the cost of running the backend if the app needs one. Plan a few days a year for adapting to new iOS and Android versions; larger extensions are billed by effort.

Do I get the source code?

Yes, in full, in your own Git repository. No closed components, no hidden dependency on our servers. If you later hire someone else, everything is ready for them.

App Development

An app is more than a website with an icon. It has to keep working offline, feel right on the device, deliver notifications reliably and pass review at Apple and Google. We use a shared codebase where it fits and native development where performance or hardware access demands it – from the first draft to release in the stores.

Where you can check it

In the App Store: the Techlogia app

Lessons, progress, notifications and a terminal to the Lab VM. Built with Flutter and connected to the same API as the website.

The Techlogia app has a fixed contract with the backend: interfaces the app uses are only ever extended, never silently changed – an automated test pins them down. Crash reports go to our own server in Germany instead of a US service. The same rules apply to apps we build for clients.

What clients bring us in for

One codebase for iOS and Android

With Flutter, both platforms share most of the code; platform-specific parts are added only where needed. That saves maintaining two separate apps for two stores.

Native development for hardware access

Swift for iOS, Kotlin for Android – where Bluetooth pairing, direct sensor access or background audio take center stage.

Desktop applications

Programs for Windows and macOS that work with files, run in the background or control local devices – with code signing and automatic updates.

Tech: Flutter, Dart, GlitchTip, APNs

How we work on it

Store release included

We take you through review at Apple and Google: listing, images, privacy details and answers to follow-up questions. The Techlogia app has been through this process itself.

Offline first

Data lives locally on the device, changes are synced as soon as there is a connection again, and conflicting changes are resolved by a fixed rule. That is the default, not an extra.

Crash reports on our own server

Crashes are reported automatically – to a server in Germany instead of a US service. Updates roll out to users gradually, so a bug doesn't hit everyone at once.
