One Flutter codebase for iOS, Android and desktop
An app for your customers, your field team or your residents, built once in Flutter and shipped to iOS, Android, Windows and macOS from the same code. Designed before it is coded, priced before it starts, and built by the team that ships its own apps through TestFlight and Google Play.
Flutter app, iOS + Android (8–12 weeks): from $45,000
A Flutter app development company builds one codebase that compiles to native iOS and Android apps, and to desktop when you need it, so you pay for one team and one roadmap instead of two. We design the screens first, fix the scope and price in writing, ship weekly builds you can install, and hand over the code, the store accounts and the backend. Fixed-scope apps start at $45,000.
Why app projects go wrong
Typical situations (not client quotes)
- We got two quotes: one for iOS, one for Android, and a third for the backend. Nobody owned the whole thing.
- The app works, but the store rejected it and the agency is gone.
- Our customers are on their phones, in Spanish, and our product is a desktop website in English.
Most app budgets are spent twice: once for each platform, and then again for the backend nobody quoted. Then the app reaches the store review and a rule nobody read sends it back. And the last mile, the one that makes an app useful, is the connection to the system you already run: bookings, orders, status, payments.
We have been through the store review process with our own apps, including a rejection and the fixes it demanded, which is exactly the experience you want on your side when it is your launch.
What we build
Flutter apps for customers, field teams and operations, with the backend and the integrations included in the scope. One codebase compiles to iOS and Android, and to Windows and macOS when the same app has to run on a counter or a desk. When a feature truly needs native code, we write it in Swift or Kotlin and keep the rest shared.
We ship our own: the platform we operate, Guiadalajara, runs on Flutter apps for consumers, businesses, delivery and support, in testing on TestFlight and Google Play, over the same backend as its web and point of sale. That is where our process comes from: screens first, weekly installable builds, a staging backend you can break, and store submission handled with you, under your developer accounts.
- UX and screen design before any code, in your brand
- One Flutter codebase for iOS and Android (desktop optional)
- Backend and API, or integration with the system you already run
- Push notifications, offline mode and payments when the scope needs them
- Weekly builds on TestFlight and internal testing on Google Play
- Store submission under your Apple and Google accounts
- Code, accounts and documentation in your name

Questions · Mobile apps
How much does it cost to build an app for iOS and Android?
With us, from $45,000 for a fixed-scope Flutter app on both platforms, backend included, in eight to twelve weeks. Screens, integrations, offline mode and payments are what move the number; the exact price is in the written scope.
Why Flutter instead of two native apps?
One codebase, one team, one release for both stores, at a lower cost than two native builds. When a feature needs native code we write it in Swift or Kotlin and keep everything else shared.
Have you published apps in the stores?
Our own apps are in testing on TestFlight and Google Play, and we have been through a store rejection and are answering it with Apple. We do not claim store-published apps until they are approved, and we will tell you where each one stands.
Who owns the app and the store accounts?
You do. The app is submitted under your Apple and Google developer accounts, the code lives in your repository, and the backend runs in your cloud account.
Can the app connect to our existing system?
Yes. Most apps we build are a front end for a system that already exists: bookings, orders, status or payments. We connect through its API or build the API if there is none.
Does the app work in Spanish and English?
Yes, by default. We are native Spanish speakers who work in English, so both languages are written from the start rather than translated at the end.
What happens after launch?
Apps need updates when iOS and Android change. A monthly support plan from $1,800 covers that, plus new features at a fixed number of hours.
