Entropy's Defiance

Minimalist launcher and time-horizon task manager.
New in version 3.1.0
A big update across reliability, speed, and design.

• Fixed tasks vanishing: an unreadable or mid-sync task file is no longer mistaken for an empty one, so your tasks are never wiped by a momentary hiccup.
• Much snappier: the app drawer keyboard and closing the drawer are now instant, and unused per-app icon loading was removed.
• Prompts to be set as the default launcher, and adds a "Default launcher" entry in Permissions (helps on phones that never ask).
• Calendar agenda redesigned: clear d
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
* Query all packages — needed to list installed apps in the drawer
* 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.
