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. Platforms cycle automatically — hover any platform to pause and 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
Stages advance automatically — hover any stage to pause and explore it. 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
- Motion & haptics spec
- Clickable Figma prototype
