App Development

An app development company
that ships and stays.

We build custom iOS and Android apps with Flutter. The work that comes out of our team already runs for 250K+ daily active users, so we know what survives real traffic. Start with a paid pilot sprint before you commit to the full build.

Why Geminate Solutions

What you get from this app development company

01

One Flutter Codebase, Both App Stores

We write the app once and ship it to iOS and Android. The UI stays pixel-accurate on both, performance sits close to native, and if you want web or desktop later, the same code stretches to cover it. One team, two stores, no duplicate work.

02

Built to Survive Real Traffic

The Flutter apps we've shipped run for 250K+ daily active users. That number forces discipline. We write automated tests, push releases through CI/CD straight to the stores, and wire up monitoring that pages us before a user ever notices something broke.

03

We Stay From Sketch to Store and After

Design, build, test, submit, and then the unglamorous part: maintenance and the updates Apple and Google demand twice a year. You deal with one team across the whole thing, so nothing falls through the gap between a designer and a developer who've never met.

04

The Backend Comes With It

An app is only half a product. We build the server side too, in Node.js or Python. REST or GraphQL APIs, real-time sync, push notifications, payment and third-party hookups. You get a working system, not a pretty front end waiting on an API that doesn't exist yet.

05

You Can See the Work as It Happens

Two-week sprints. A standup most mornings, a demo at the end of each one, and a shared board you can open any time. We'd rather you catch a wrong turn in week three than at the final handover, so the progress stays in the open the whole way through.

06

Start With a Paid Pilot, Not a Contract

Before you commit to a full build, we run a one-week pilot on a real slice of your project. You read our actual code, watch how we communicate, and see the pace for yourself. If it's not a fit, you walk away knowing exactly what we ship.

Track Record

A mobile app development partner with mileage

We've shipped 50+ products and we hold a 4.9 star rating across 24+ client projects, which is the kind of rating you only keep by shipping work people stand behind. The work speaks louder than the rating, though.

One of our learning apps runs for more than 250,000 daily active users. An IoT fleet-tracking system we built tracks 30,000+ vehicles in real time. We've carried an exam platform through 10 million-plus requests a minute on results day without it falling over. None of that is theory. It's code in production that handles load most apps never see.

Frequently asked questions

Why does this app development company build with Flutter instead of native?+

One codebase instead of two. You get near-native performance on iOS and Android without paying for, and then maintaining, two separate apps that drift apart over time. The Flutter apps we've shipped run for hundreds of thousands of daily active users, so we've put it through the kind of load that exposes a framework's weak spots. Native still wins for a narrow set of cases, heavy AR, deep platform-specific hardware work, and we'll tell you honestly when yours is one of them.

How long does it take to build a mobile app?+

A focused MVP usually lands in 6 to 12 weeks. A full-featured app with a real backend behind it runs 3 to 6 months. The honest answer is that it depends on how many screens, how many integrations, and how custom the interface gets. We give you a real timeline after we've sat with your requirements, not a number pulled out of the air on a sales call.

Do you handle App Store and Google Play submission?+

Yes, the whole thing. We take the app through both the Apple App Store and Google Play review process, which includes meeting each store's guidelines, preparing the screenshots and listing copy, and dealing with the rejections that happen to almost everyone the first time around. You don't need an Apple Developer account headache on top of building a product.
