Day Mark - Work Log

Day Mark is a to-do app that remembers what you finished.

• Calendar heatmap: see what you did on any day at a glance. Color only shows how much got done — it's a ruler, not a medal. No streaks, no scores.
• Lead time: every task shows how long it took from creation to completion.
• Journal: write a few lines about a day and read them next to what you finished.
• Today and To Do: Today holds today’s tasks. To Do keeps unfinished tasks planned earlier, later, or without a date. Mark important tasks as a priority to keep them at the top.
• Focus: Pomodoro or stopwatch, with an optional soundscape (rain, tide, a distant bell) and a soft ticking clock, all synthesized on the device.
• Your data stays yours: syncs across iPhone, iPad and Mac through your own iCloud, and the app keeps a readable Markdown/JSON archive you can copy from the Files app.
• No servers, no sign-up, no ads, no tracking.

Complete backups: choose a folder outside the app in Settings for automatic full copies, or export manually. After reinstalling, open a retained backup as a separate local copy. Recovered copies do not sync with iCloud; you can return to your original data. Keep the external files. A file written to a folder does not confirm its cloud upload.
