React Native, one codebase
iOS and Android from a single codebase where that serves the product, and honest advice about when it does not.
Services — 04
iOS and Android apps, taken all the way through review
React Native from one codebase where that is the right call. We have built and shipped our own social app to Apple's App Store, with an in-app currency and gifting economy, so the last ten percent holds no surprises.
Typically
From €15,000 for a full app build
The problem
Most of the cost of a mobile app is in the part nobody demos: store review, payment approval, release pipelines, crash reporting, and the migration you need when the data model turns out to be wrong on devices you cannot reach.
Idolify was our own company, built alongside full-time work and published on the App Store. No client to shield us from any of that. When we quote a mobile project, we are quoting from having paid those costs ourselves.
What’s included
Everything below, as standard.
In-app purchases and virtual currency
Payment flows, balance integrity and abuse considerations — an in-app economy is the part of a mobile build with actual teeth.
Auth and SSO
Sign-in that works across devices and reinstalls, including single sign-on where your users expect it.
Offline-tolerant data
Local-first storage and sync for apps used somewhere with unreliable signal, with conflict rules agreed rather than assumed.
Release pipelines
App Store and Play Store release automation, so shipping an update is a routine action rather than an event.
Crash, analytics and monitoring
Instrumentation from launch, because on mobile you cannot ssh into a user's phone to find out what happened.
Sound like the right fit?
You probably need this if
Any of these sound familiar.
01You need one product on both iOS and Android
02An agency quoted you two separate native builds
03Your app works in demos and fails on real connections
04Nobody on the team has been through store review before

Work of exactly this kind.
Questions
React Native or native?
React Native for most products with shared logic and standard UI, which is the majority. Native when you are deep in platform-specific capability. We will tell you which one your product is rather than defaulting to whichever we prefer.
Can you publish under our developer account?
Yes, and we would prefer to — your app should live in your account from the start, the same way your code lives in your repository.
Do you handle store rejections?
Yes. Rejections are routine rather than exceptional, and knowing which reviewer objections are negotiable is most of the skill.
