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.
