I write mobile apps for iOS and Android. I've built mobile apps since 2021: Flutter at atFirstSite (Jun 2021 to Sep 2023) and on my thesis app, then native Android in Kotlin and Jetpack Compose at Deloitte since Feb 2024, on three retail e-commerce apps. Below are the ones I build on my own time.
- Headspare: see whether your AI coding subscriptions will last until they reset. Mac, iPhone, Apple Watch and Android. Swift/SwiftUI and Kotlin. Waitlist at headspare.app.
- Healpen: journaling based on expressive writing. Flutter, Hive, Firebase. TestFlight beta.
- Peakward: running coach that adapts training plans from HealthKit data. Flutter. Private beta.
- Noima: spaced-repetition flashcards. Flutter, Supabase, FSRS. In development, noima.app.
- famon: Firebase Analytics CLI for Android and iOS logs. Dart. v1.5.2 on pub.dev.
- zam_ui: Flutter design system with OKLCH tokens. Dart. BSD-3.
- agent-skills: the coding-agent skills I use for Flutter work. On GitHub.
