Businesses whose customers live on their phones
If your clients would open an app more often than a website, Starter turns your site into an app with push notifications in 7 days. It is the quickest way to test whether customers actually use an app.
Websites & apps
One mobile app for iOS and Android, shipped to both stores
React Native and Expo let one codebase ship to both the App Store and Google Play. We build your app with login, push notifications and your branding from the first screen, then package it and handle the submission under your own Apple and Google accounts. Over-the-air updates mean small fixes reach users without waiting for another store review.
Who it is for
Products that need a real native app
Pro is a real iOS and Android app with login and notifications, with store submission included.
Apps with offline use or purchases
Scale covers 3–4 flows, works offline, supports in-app purchases and is published to both stores.
How it works
- 01
Scope the flows
We agree which flows the app needs and what happens on the first screen, and lock it in a short statement of work. Anything extra goes to the backlog for a later release.
- 02
Build once for both platforms
React Native, Expo and TypeScript give one codebase for iOS and Android, with authentication, push notifications and your brand built in.
- 03
Package and submit
We package the app and handle the App Store and Google Play submission in your developer accounts.
- 04
Updates after launch
EAS deploy and over-the-air updates let small changes reach users without a new store review. Larger releases with new native features still go through store review as usual.

Questions
How much does an iOS and Android app cost?
Starter is €3,990, Pro €9,990 and Scale €19,990, fixed and excluding VAT. Apple and Google charge their own developer account fees directly to you. A 50% deposit locks the build window; the balance is due on delivery.
How long until the app is in the stores?
7 days for Starter, 14 days for Pro and 21 days for Scale to build and submit. We prepare and submit the build; review time itself is decided by Apple and Google.
Who owns the app?
You do. The repository is yours and the app is published under your own Apple and Google developer accounts, so there is nothing to transfer later. Over-the-air updates run through your own Expo account as well.
How is user data handled?
The backend is hosted in the EU under a data processing agreement. We help you fill in the App Store and Google Play privacy declarations to match what the app actually collects.
What do you need from us?
Apple and Google developer accounts (or permission to set them up in your name), your brand assets, the flows the app needs and one person who approves builds during the sprint. Quick approvals keep the timeline.
