Android and iOS apps that feel native.
Flutter when one codebase should cover both stores. Kotlin and Swift when the app needs to go deep into the platform. Either way: on-device ML where it helps, offline-first data, and a clean store release under your accounts.
Deliverables
What you get, in writing.
Cross-platform with Flutter
One Dart codebase for Android and iOS, with platform channels where native APIs are needed and smooth 60fps UI on mid-range phones.
Native Android in Kotlin
Jetpack Compose, coroutines, and Material 3 for apps that live close to the hardware: camera, sensors, background work.
Native iOS in Swift
SwiftUI and Swift concurrency, following Apple's Human Interface Guidelines so the app feels at home on iPhone.
On-device ML
OCR, classification, and embeddings that run offline with LiteRT, Core ML, or ML Kit, with latency measured on real devices.
Backend & offline sync
Firebase, Supabase, or your own API, with local-first storage and sync that survives a patchy network.
Store release & handoff
Signing, CI builds, privacy labels, store listings, and review submission, all published under your own developer accounts.
60fps
Frame-rate target on mid-range Android
100%
Published under your own store accounts
30d
Support after store release
Tools we reach for · documented, replaceable, no lock-in
Process
How it runs.
Four steps, agreed before any code is written: what the system should do, what it should refuse, and how success gets measured.
- 01
Scope & flows
Screens, user flows, target platforms, and which features need native APIs, including the Flutter-or-native call, agreed before code.
- 02
A build on your phone
A working build via TestFlight or Play internal testing in the first week, not just a design file.
- 03
Build & test on real devices
Features against scope, tested on low- and high-end devices, with crash reporting wired in from day one.
- 04
Release & handoff
Store listings, signing, review submission, and 30 days of support after launch.
