Mobile apps users actually keep.
Native iOS (Swift), Android (Kotlin), and cross-platform (Flutter, React Native) — engineered to ship, retain, and grow.
PLATFORMS
Pick your platform mix
Native, cross-platform, or both. Click any tab to explore — we'll recommend based on your audience, performance needs, and team.
iOS (Swift)
Best graphics, best haptics, best App Store reviews. The ceiling for what mobile UX can feel like — when you need premium feel and deep iOS integrations, native wins.
Best for: Premium UX, gaming, AR/VR, deep iOS integrations.
- SwiftUI & UIKit hybrid builds
- Widgets, ARKit, HealthKit, Live Activities
- Apple Pay & in-app purchase
- watchOS companion
Android (Kotlin)
3B+ devices, deep system access, and the freedom Apple won't give you. Modern Kotlin with Jetpack Compose. Material 3 design language baked in.
Best for: Global reach, hardware access, custom backgrounding.
- Jetpack Compose declarative UI
- Material 3 dynamic color
- Background workers & foreground services
- Wear OS companion
Flutter
One codebase, two stores, near-native performance. Our default cross-platform for new product builds — design parity across iOS and Android, and an animation-rich UI toolkit.
Best for: Speed to market, design parity, animation-rich UI.
- Single Dart codebase → iOS + Android
- 60–120 fps animations via Skia/Impeller
- Hot-reload + Firebase + Riverpod patterns
- Pixel-perfect parity across platforms
React Native
Great when you already have a React team. OTA updates via Expo let you ship fixes without app-store review — perfect for iteration-heavy products.
Best for: Web-team reuse, OTA-heavy products, fast iteration.
- Reuse React skills + npm ecosystem
- Expo Application Services (EAS)
- OTA updates without store review
- Bridge to native modules when needed
FLAGSHIP
Native vs cross-platform: an honest matrix
We've shipped both. Here's when each one wins — without the sales pitch.
| Consideration | Native (Swift / Kotlin) | Cross-platform (Flutter / RN) |
|---|---|---|
| Time to ship two stores | 2× the work | Single codebase |
| Performance ceiling | 60–120 fps consistently | 60 fps comfortably |
| OS integrations (Widgets, ARKit, HealthKit) | Day-one support | Plugin lag |
| Engineering headcount | 2 teams | 1 team, both platforms |
| OTA / hot-fix updates | Store review 24–72h | Expo / CodePush in minutes |
| Long-term maintenance | 2× SDK upgrades | One upgrade, both |
| Design fidelity per platform | Pixel-perfect HIG / MD3 | Branded, not platform-native |
| Wins tally | 0 clean wins | 0 clean wins |
Our default rec: Flutter for most apps. Native for premium UX, deep OS integrations, or when you already have a team.

APP LIFECYCLE
Strategy · Design · Build · Launch · Grow
Click any stage — or watch it walk through. A 5-stage flow that takes most apps from concept to store in 12–16 weeks.
Strategy
Product brief, persona work, monetization model, platform recommendation, and a fixed-price scope. We learn the user before we recommend the platform.
- Persona & jobs-to-be-done
- Monetization model
- Native vs cross-platform call
- Fixed-price SoW
Design
Interactive Figma prototype, motion specs, and a design system tuned to iOS HIG and Android Material 3. Every screen approved before code.
- Wireframes for every flow
- Hi-fi HIG + Material 3 screens
