Daymark is a minimal, local-first Bullet Journal application for Linux and Android. It keeps the journal, reflection, and deliberate migration decisions at the center while avoiding the usual digital productivity clutter.
Daymark is offline-first, stores journal data in an encrypted local database, and follows the core Bullet Journal method with a small number of explicit digital adaptations.
- Daily Log with Rapid Logging for Tasks, Events, and Notes
- deliberate Task completion, migration, scheduling, and discard
- Daily and Monthly reflection over unresolved Tasks
- Monthly Log with Calendar, Tasks, and optional finite Trackers
- rolling six-month Future Log with arrival review
- Collections with owned entries and references
- deliberate Index and local read-only Search
- built-in Signifiers for priority, inspiration, and exploration
- encrypted Backup / Restore
- plaintext Open Export to JSON or Markdown
- automatic locking after inactivity and host-system lock events
- responsive Linux and Android interface with System, Light, and Dark appearance
- English, Portuguese (Brazil), and Spanish application localization
Daymark is intentionally narrow:
- faithful to the core Bullet Journal method
- digitally minimal
- local-first and offline-first
- encrypted at rest
- explicit about Daymark-specific adaptations
- free of accounts, feeds, advertising, gamification, streaks, productivity scores, and attention-seeking UI
Automation must not remove reflection or deliberate migration decisions from the method.
Daymark currently targets:
- Linux x64, distributed as Debian package and AppImage
- Android
The project uses Flutter and Dart. The exact supported toolchain and dependency set are documented in the developer documentation and lockfile.
