What is mobile app development?

Mobile app development is building software that runs natively on phones and tablets, distributed through the App Store and Google Play. Codiot builds native iOS and Android apps and cross-platform apps in Flutter and React Native, choosing the approach based on your performance needs and budget, not a house preference.
Capabilities

What we build.

Native iOS and Android

Swift and Kotlin for apps where performance, platform-specific features, or App Store positioning matter most.

Cross-platform with Flutter

One codebase, native-feeling apps on both platforms, faster to build and cheaper to maintain.

React Native for web-adjacent teams

A strong option when your team already ships React and wants shared logic between web and mobile.

Backend and API integration

Push notifications, offline sync, payments, and the server-side systems mobile apps depend on.

App Store and Play Store launch

Submission, review compliance, and the metadata and screenshots that affect discoverability.

How it works

How it works with Codiot.

01

Prototype the core flow

We build the one screen sequence users will touch most, before designing the rest of the app around it.

02

Build on real devices

Tested on actual hardware throughout, not just simulators, because that's where performance problems show up.

03

Ship, then iterate on usage

Post-launch analytics tell us what to fix first; we don't guess at version two.

FAQ

Common questions, answered plainly.

Should I build native or cross-platform?
Cross-platform (Flutter) is right for most business apps: faster, cheaper, and close enough to native for almost every use case. Native makes sense when you need deep platform integration, top-tier gaming performance, or you're already committed to one platform.
How much does a mobile app cost?
It depends on feature scope, backend complexity, and whether you need one platform or both. We scope a focused MVP first and give you a fixed estimate after a short discovery call.
How long does it take to build an app?
An MVP ships in 10-14 weeks. More complex apps with custom backend logic or hardware integration run 4-6 months for a first release.
Do you handle App Store submission?
Yes, including the parts founders usually get stuck on: privacy policy compliance, review rejections, and the store listing itself.
What happens if Apple or Google rejects the app?
We handle resubmission as part of the launch phase. Most rejections are fixable within a day or two once you know the actual reason, which their review notes rarely spell out clearly.
