30 Day Challenge - LockIn301.1.0 - App Store

Want to stick with a 30 day challenge? LockIn30 turns one habit into a daily tracker with photos, streaks, and a finish-line timelapse. No ads, no account needed.

Pick a habit from a library of 36 across fitness, nutrition, mind, sleep, learning, productivity, spiritual, and relationships. Or create your own. Set a duration from 7 to 365 days (30 is the default). Choose tough mode (strict, with a Be Honest recovery if you miss a day) or soft mode (forgiving, no penalty). Log each day with the input that matches your habit: checkbox, counter, minutes, photo, text, or measurement.
