Every day you keep a habit turns one square green. Skip a week and you see the gap. That is the whole idea: a year of your life on one screen, honest and impossible to argue with. HeatMap is a habit tracker built around the GitHub-style contribution grid. Open it, tap once, done. No cluttered dashboard, no ads, no guilt-tripping notifications. THREE WAYS TO TRACK - Yes / No — did you go to the gym today? - Counter — pages read, glasses of water, cups of coffee. - Timer — start it and log real minutes of practice, study or meditation. Set a daily target, or a gentler one like "4 times a week", and the grid follows your rule instead of shaming you for a rest day. STATISTICS THAT ACTUALLY TELL YOU SOMETHING - Current streak, personal record, total days - Your most productive weekday, and weekdays vs weekends - Six-month trend, month-over-month change and a year-end projection - Your longest gaps, so you can see where a habit usually breaks Tap any number to open the full chart behind it. RIGHT ON YOUR HOME SCREEN - Home Screen and Lock Screen widgets showing your live heatmap - A Control Center button to log a habit without opening the app - Siri Shortcuts: "Hey Siri, mark meditation" WORKS OFFLINE, SYNCS WHEN YOU WANT Start tracking immediately — no account, no email, no onboarding quiz. Everything is stored on your device and keeps working on a plane or underground.
