Launch Your Mobile App in 10-14 Weeks — Native Performance, Cross-Platform Savings
We build iOS and Android apps that feel native, load in <2 seconds, and actually get approved. 100% App Store approval rate, 20+ apps live, 100K+ active users. React Native or native Swift/Kotlin — we recommend what's best for you.
Why Startups Choose Us Over Big Agencies
Speed Without Compromise
Most agencies quote 6+ months. We deliver in 10-14 weeks with weekly demos. React Native lets us build iOS and Android simultaneously. You see progress every Friday. Beta ready by week 8, live by week 12.
Native Performance, Cross-Platform Cost
React Native gives you 40% cost savings without sacrificing performance. <2 second load times, butter-smooth 60fps animations, native UI components. When you need true native (games, AR), we build with Swift/Kotlin.
100% App Store Approval
We've launched 20+ apps with 100% App Store approval rate. We know Apple's guidelines inside out: privacy policies, permissions, metadata, screenshots. No surprises, no delays, no rejections.
Full Code Ownership
You own every line of code. Full GitHub access. No vendor lock-in. Want to take over development? You can. Want us to maintain it? We do that too. 3 months of free bug fixes included.
Your App in 10-14 Weeks: Design to Launch
Week 1-2: Design & Architecture
UI/UX design for iOS and Android. We create high-fidelity prototypes you can click through. User flows mapped. Tech stack chosen (React Native or native). API architecture planned. No coding yet—just validation.

We build features in priority order: auth, core screens, navigation. You see working builds every Friday via TestFlight/Firebase. Real device testing starts week 5. Backend integration by week 6.
Week 9-10: Polish & Performance
Animation refinement, loading states, error handling. Performance optimization: <2s load times, 60fps animations. Offline support. Push notifications. Payment integration (Stripe, Apple Pay).

Screenshots, descriptions, keywords (ASO). Privacy policy, terms. App Store submissions. We handle all requirements. Beta testing with real users. Final QA across devices.
