How we deliver
- 1 sprint
- Daily standups
- Weekly demos
We build mobile apps that ship to production — not just prototypes that gather dust. Every app is tested on real devices, optimized for store approval, and built to retain users.
Whether you need a consumer app, an enterprise mobile tool, or a cross-platform solution, we handle design, development, QA, and app store submission end-to-end.
Our React Native and Flutter teams build once and deploy everywhere — without sacrificing native performance or platform-specific UX conventions.

Discovery & scoping

Common questions
Do you build for iOS and Android?
Yes — we build native iOS (Swift), native Android (Kotlin), and cross-platform (React Native, Flutter). We recommend the right approach based on your timeline, budget, and feature requirements.
How long does a mobile app take to build?
An MVP with core features typically takes 8–14 weeks. A full consumer app with social features, payments, and notifications takes 16–24 weeks depending on complexity.
Do you handle App Store and Google Play submissions?
Yes — we handle full submission including metadata, screenshots, and compliance review. We have 100+ apps approved on both stores.
Can you maintain and update our existing app?
Absolutely. We offer retainer-based maintenance covering OS updates, new features, bug fixes, and performance monitoring.
What does the development process look like?
We follow 2-week sprints with a working build at the end of each sprint. You get a staging app link to review every 2 weeks before the next sprint starts.
Should we build native apps or one cross-platform app?
For most products one React Native or Flutter codebase covers iOS and Android with a native feel, and we hand-tune the platform-specific parts such as gestures, push notifications and deep links. Swift and Kotlin are the better choice when the app needs maximum performance or deep platform features.

Founders we shipped mobile app development for.
Real founders, on camera, talking about what it was like to build with Krapton — what we got right, what we shipped, and what they got out of it.
“Quick, Professionals, Always going above and beyond.”
“Rush Racing League needed more than just a website — we needed a full system that could run as fast as our races. Krapton built exactly that. Live race results flow automatically from Discord straight to the website — no manual updates, no delays. Team management is seamless, driver rosters update in real time, and our admin panel lets us control every piece of content on the site without touching a single line of code. They didn't just build us a product — they built us a machine. Huge thanks to the Krapton team.”
“Krapton built our admissions platform end-to-end — content, SEO, dashboards. Enquiries from international students grew steadily after launch.”
- Admissions platform delivered ahead of schedule
- SEO + content built into the launch, not bolted on after
- Ongoing engagement for new courses and dashboards
