HART: Habit & Routine Tracker

HART: Habit & Routine Tracker とは？

Most habit trackers are either too simple or too cluttered. HART sits in between — it has a built-in focus timer per habit, per-habit daily reminders that automatically skip if you've already completed the habit that day, and a clean dark interface with no ads or gamification. The free tier is genuinely usable at three habits. Pro unlocks unlimited habits, cloud sync, and full statistics. No subscription required — there's a one-time lifetime option.
