✨🐙 A GPL Licensed Cognitive Behavioral Therapy app for iOS and Android. Currently a teaching tool
Quirk is a React Native / Expo app that walks users through CBT thought records — you log an automatic thought, identify cognitive distortions, and write a challenge. It's explicitly unmaintained and was open-sourced after a failed YC-backed startup pivot. Useful as a teaching example of a real production React Native app, not as something you'd ship to users today.
The design philosophy is unusually principled for a side project — explicit rules about not coupling features (no mandatory mood tracking), not abusing notifications, and not creating engagement loops in a mental health context. The GPL license is intentional and meaningful here. Expo + React Native with fastlane CI, multi-locale support across 12+ languages, and a clean separation between thought entry and the distortion reference material shows solid architecture for the scope. The README's business model post-mortem is genuinely useful reading for anyone thinking about sustainability for health apps.
Abandoned since mid-2024 and the Expo SDK version is ancient — you will spend your first day just getting it to build before writing a line of feature code. No backend whatsoever: thoughts are stored locally only, no sync, no backup, which was a deliberate choice but means data loss on reinstall is permanent. The recommended fork point is a specific commit rather than a stable branch or tag, which is an odd handoff. Test coverage appears to be zero.
