Original Work

OpenTransition is based on TransTracks, which was written and maintained single-handedly by Cassie Wilson (<contact@transtracks.app>). TransTracks was retired from the Google Play Store in 2025 and its source repository is now archived at github.com/TransTracks/TransTracks-Android. OpenTransition is the active continuation of this work.

What Changed in the Fork

OpenTransition maintains the core functionality and design philosophy of TransTracks while:

  • Rebranding with a new package name (com.shelbeely.opentransition)
  • Independent maintenance and development
  • Community-driven improvements and features
  • Separate deployment on app stores
  • Expanded features: audio tracking, biometric auth, optional encrypted database, decoy vault, CameraX face-detection camera, Wear OS companion

Acknowledgments

We are deeply grateful to Cassie Wilson, who built TransTracks essentially on her own and chose to release it under GPL v3 — creating a valuable tool for the transgender community and ensuring that, when she stepped away in 2025, the community could carry it forward. Though TransTracks itself is no longer active, its legacy lives on in OpenTransition.

Original TransTracks Features

All core features in OpenTransition originated from Cassie Wilson's TransTracks:

  • Photo tracking system with face, body, and custom categories
  • Milestone management and tracking
  • Gallery and photo comparison views
  • Privacy features (app lock, train mode)
  • Data import/export functionality (.ttbackup format)
  • Firebase integration for cloud backup
  • Theme customization
  • And many more features

Migrating from TransTracks

If you are a former TransTracks user, your data can be migrated to OpenTransition using the .ttbackup export file from TransTracks. See Import & Export for instructions.
