One codebase, both app stores, in 10 weeks
Flutter apps for iOS and Android from a single codebase, with the backend built by the same two engineers.
Who it's for
This is built for you if…
- Founders who need iOS and Android without paying for two native teams
- Businesses adding a mobile app to an existing product or workflow
- Teams that got a Flutter quote from an agency measured in quarters
- Products where the app and its API must be designed together, not by two vendors

FAQ
Common questions
Why Flutter instead of native or React Native?
One codebase covers roughly 95% of typical app scope for both platforms, which cuts cost and timeline nearly in half versus two native teams. We ship Flutter apps in production, including an exam-prep platform, and we will tell you plainly if your app is the rare case that needs native (heavy AR, deep hardware work).
How long until it is on my phone?
You get the first installable build within 14 days, then a new build every week. Store submission adds 1 to 2 weeks at the end for Apple and Google review; we handle both.
Do you build the backend too?
Yes, and we recommend it. Most 'mobile agency' failures are actually API failures. The same two engineers design the app and its NestJS backend together, so the contract between them is typed and tested, not negotiated over email.
What does maintenance cost after launch?
The first 30 days of defect fixes are free under warranty. After that, most apps need $500–$1,500 per month for OS updates, store compliance, and small improvements, depending on release cadence.
