Production Mobile Apps iOS & Android

Cross-platform mobile apps with native performance, offline caching, and verified quality gates.

Why businesses build mobile apps with Flutter

Flutter compiles directly to native ARM code with unified logic across iOS and Android — one team, one codebase, two stores.

Render

Native Render Performance

Skia and Impeller graphics engines draw every pixel directly — no web views, no JavaScript bridge latency. Your app feels native because, at the rendering level, it is.

2 Stores

Build Once, Ship Twice

One Dart codebase means business logic, auth, API calls, and offline caching are written once and tested everywhere. Every feature you pay for ships to both stores — roughly one build's budget instead of two, and no "iOS has it, Android is coming" gap for your users.

Gates

Contractual Engineering Quality

Every PR is validated against strict static analysis rules, formatting linters, and architectural boundaries before merge. It's in our published standard — and in your contract.

OUR TRANSPARENCY COMMITMENT

When we don't recommend Flutter

Flutter is our default for marketplaces, booking, and operations apps — the products service businesses run on. It's not our default for everything. When a product demands deep platform integration or iOS-first consumer polish, we build native — our own product, rmbrme, is native Swift for exactly that reason.

On your scoping call, we'll tell you which stack your product actually needs. If the honest answer is native — or "you don't need an app yet" — that's the answer you'll get. We sell the right stack, not our stack.

Flutter questions founders actually ask

Will Google kill Flutter?

It's the right question — everyone's seen Google's product graveyard. Flutter today runs a massive production footprint: Google's own revenue-critical apps, plus companies like BMW and Toyota, and a large share of new apps shipping to both stores. More to the point: your protection isn't a prediction about Google. It's that you own a documented, standards-compliant codebase in your own repository — written to be maintained by any competent team, whatever the ecosystem does. That's true of everything we build, in any stack.

Can Flutter access native device features like Bluetooth, camera, and biometrics?

Yes. Flutter connects through platform channels to Swift on iOS and Kotlin on Android, so device capabilities are fully available. For the app categories we build — marketplaces, booking, field operations — you get native-level performance and full hardware access. (For edge cases like heavy AR or graphics-intensive work, see the section above: that's when we'd recommend native, and we'll say so.)

What does one codebase actually save me?

Roughly one build instead of two: one team, one feature implemented once, one test suite, one release process feeding both stores. It doesn't make development free or twice as fast — it means you stop paying the iOS/Android duplication tax, which is usually the largest line item in going cross-platform.

I already have a native (or half-built) app. Can we move to Flutter?

Sometimes you should; often you shouldn't. Start with a Product Rescue audit — $4,500 gets you an honest assessment of what you have and a side-by-side on rebuild vs. repair vs. coexist (Flutter can be added screen-by-screen to an existing app). The audit fee is credited toward the build if we do it.

Do you handle Apple App Store and Google Play submissions?

End to end — certificates, provisioning profiles, privacy declarations, screenshots, and review submission, including every resubmission until your app is approved. No one can guarantee Apple's decision; what we guarantee is that you never deal with the review process alone, and we own it until it's done.

Who maintains a Flutter app long-term?

Your code is documented to our published standard and 100% yours, so any competent Flutter team can maintain it — and Flutter developers are one of the largest cross-platform talent pools if you hire in-house. Prefer we stay on? Lightweight monthly maintenance SLAs cover OS updates, security patches, and minor enhancements.
