30 Day Challenge - LockIn30

About

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. Answers to your habit challenge questions • How long does a 30 day challenge actually take to stick? • What is the best 75 Hard alternative for a single habit? • How do I track a habit streak without breaking it? • What happens if I miss a day on a strict challenge? • Can I run more than one habit challenge at a time? • How do I share my progress with a daily photo timelapse?
