About Entropy's Defiance
Entropy's Defiance is a minimalist Android launcher and task manager built around
five time horizons: Today , This Week , This Month ,
This Year and This Life . Tasks are stored in plain JSON, so they
sync cleanly with Syncthing or any folder-sync tool, and a small terminal UI is
available for editing the same file from a Linux laptop.
Features
* Time-horizon task list — peek at the next horizon, swipe a task left or right to move it across horizons
* Minimalist home screen with a focused task view
* App drawer with frequency-ranked apps and instant text search
* Calendar widget with free-time calculation across selected calendars
* Zen Mode for distraction-free focus on a single task
* Optional double-tap to launch the dialer
* Accent colour — follow your system's Material You palette, pick a preset, or set a custom colour
* Left-handed mode — mirror the controls to the left
* Plain-JSON storage that syncs over Syncthing
* Guided intro to the five-horizon philosophy — replayable from Settings → Introduction
Permissions

* Read calendar — only used for the calendar widget; you can deny it
* Set wallpaper — used by the launcher to restore your wallpaper
* Bind device admin — only requested if you opt in to Zen Mode's
Do Not Disturb integration
The app is offline-first and contains no trackers, no analytics, and no ads.

Off by default; enable it under Settings → Zen Mode. • Hide and rename apps from the drawer's long-pres
