Your app is slow.
We fix that.
Permanently.
We take your React Native, Flutter, or Electron app and rebuild it as a fast, beautiful, truly native experience — in Swift, Kotlin, or both. Users notice. Ratings improve. Revenue follows.
Your users can feel the difference. They just can't explain it.
Cross-platform frameworks like React Native, Flutter, and Electron are built for developer convenience — not user experience. The result is apps that feel slightly off: janky animations, delayed responses, drained batteries, and App Store reviews that say "this app used to be better."
A native rewrite changes everything. When your app is built specifically for the platform it runs on, it uses less memory, responds instantly, and feels like it belongs. Users stay longer. They spend more. They leave better reviews.
The numbers don't lie.
Measured on a real HealthTech app — React Native before, SwiftUI after. Same device, same network, same data.
Benchmarks measured on iPhone 14 Pro, iOS 17.2. Results vary by app complexity.
From clunky to native in four steps.
Free App Audit
We analyze your existing app — codebase, performance metrics, App Store reviews, and user complaints. You get a detailed report showing exactly what's slow, what's broken, and what a native rewrite would fix. No cost, no commitment.
Rewrite Proposal
We deliver a fixed-price proposal with a clear scope, timeline, and expected outcomes. No hourly billing, no scope creep surprises. You know exactly what you're getting before you sign anything.
Native Rebuild
Our team — augmented by cutting-edge AI tools — rebuilds your app in Swift (iOS/macOS) and/or Kotlin (Android). We maintain feature parity with your existing app while eliminating every performance bottleneck.
Launch & Handoff
We submit to the App Store and Google Play on your behalf, handle the review process, and hand you a clean, documented codebase you fully own. We stay on for 30 days post-launch to fix any issues at no extra cost.
The business case for going native is overwhelming.
3–8× Faster Performance
Native apps use platform-optimized rendering pipelines. No JavaScript bridge, no overhead. Just raw speed.
Higher App Store Ratings
Performance and feel directly correlate with ratings. Our clients consistently see 0.5–1.5 star improvements post-rewrite.
Lower Battery & Memory Usage
Cross-platform frameworks are notoriously resource-hungry. Native apps use a fraction of the memory and extend battery life.
You Own the Code
We hand you a clean, documented, fully native codebase. No vendor lock-in, no proprietary framework dependencies.
App Store Compliance
Apple and Google increasingly favor native apps. Avoid rejections, pass review faster, and unlock features unavailable to cross-platform apps.
Future-Proof Architecture
Built on the same foundation Apple and Google use internally. When new OS features ship, your app can use them immediately.
We're not a freelancer. We're not an agency. We're better than both.

Fixed prices. No surprises.
Every project starts with a free audit. We only take on projects we know we can deliver. If we can't, we'll tell you upfront.
For simple apps with 3–8 screens and no complex backend integrations.
For established apps with complex UI, backend integrations, and both platforms.
For large, complex apps with custom requirements, compliance needs, or tight timelines.
Pay a fully refundable $500 deposit to lock in your project slot and kick off the free audit. The deposit is applied 100% toward your chosen package when you're ready to proceed.
What happens after a native rewrite.
"Our React Native fitness app was sitting at 3.1 stars with hundreds of 'so laggy' reviews. Six weeks after the SwiftUI rewrite it hit 4.7. Monthly churn dropped 22%. The rewrite paid for itself before the invoice was even due."
"We'd been putting off a native rewrite for two years because we thought it would take forever and cost a fortune. They delivered in 43 days, under the fixed price, and the Kotlin codebase is cleaner than anything our internal team had written. Our Android crash rate went from 4.2% to 0.3%."
"The free audit report alone was worth more than what most agencies charge for a discovery sprint. They found a memory leak in our Electron wrapper that was causing 40% of our 1-star reviews. Post-rewrite, our support ticket volume dropped by half."
