Mobile apps for iOS and Android.

Two apps of my own are in the stores. I do the same work for you: one codebase, both platforms, submission and operation included.

Screens from shipped apps

Bvunza AI and iAdvertise are apps of my own — live on the App Store and on Google Play. Every screen here is a screenshot of the published app, not a draft and not a mock-up.

One codebase, two stores

React Native where it fits, native where it has to be. You pay for one build and get iOS and Android.

Offline first

Data lives on the device and syncs as soon as there is a signal again. No empty screen in the basement.

Submission and operation

App Store and Google Play, review requirements, privacy declarations, updates and emergency fixes — I take care of it.

From the idea into the store
01

Scoping

Two weeks: screens, data model, device constraints. After that we know what the first release does — and what it deliberately does not.
02

Building

Every two weeks a build you open on your own device. Not a presentation — the app.
03

Test flight

TestFlight and Google Play beta for your team. Feedback comes from real working days, not from a workshop.
04

Submission

App Store review and Play Console, privacy declarations, store copy and imagery in DE, FR and EN.
05

Operation

Updates for new iOS and Android releases, fixes, extensions. The stores do not wait.

An app in mind?

Write to me about what it should do and who for. Within 24 hours I will tell you whether an app is the right route — or whether a web app on the phone is enough.
