Show up for 30 days. Daily reminders, streak tracking & a private photo journal — all in one calm, beautiful app. Your future self starts here. 30 days. One habit. Everything changes. ThirtyDays is the calm, beautiful way to actually finish a 30-day challenge. Pick one habit, show up every day, and watch a streak — and a new identity — quietly build. No feeds. No streak shaming. No 47 things to track at once. Just one challenge, one daily check-in, and the science-backed window your brain needs to rewire. — WHAT YOU GET — • ONE ACTIVE CHALLENGE — radical focus. Finish it, then start the next. • DAILY CHECK-IN — log a photo, a thought, or just tap done. • SMART REMINDERS — a single nudge at the time you choose. • REAL STREAK MATH — a missed day breaks the streak but never the challenge. Keep going. • MILESTONE MOMENTS — celebration notifications on days 7, 15, 21 and 29. • PRIVATE PHOTO JOURNAL — your 30-day story in pictures, saved to your iCloud. • GORGEOUS DESIGN — animated cloudy gradients, glass surfaces, SF Pro typography. Built natively for iOS 26. — CHALLENGES PEOPLE ACTUALLY DO — Running · Gym · Drink 2L water · Cold showers · Eat clean · Sleep 8h Meditation · Reading · Journaling · No social media · Gratitude · Breathwork Drawing · Guitar · Coding · Writing · Language learning · Piano Wake early · No alcohol · Cook at home · 10k steps · Declutter …or build your own. If you can do it once a day, you can run a 30-day challenge with it. — THE SCIENCE — Neuroscience shows consistent daily reps rewire your brain in 21–66 days. Thirty is the sweet spot: long enough to make it real, short enough to actually finish. — WHY THIRTYDAYS, NOT ANOTHER HABIT TRACKER — • One habit at a time. Trying to fix everything at once is how you fix nothing. • Calendar-day check-ins (00:00–23:59) — no anxious rolling 24-hour windows. • Your longest streak is saved on every run, even if a day slips. • No accounts. No feeds. No social scores. No ads. Ever. • Built native in SwiftUI for iOS 26 — fast, fluid, light on battery. — PRIVACY FIRST — Your photos, reflections and progress live in your iCloud, not on our servers. No sign-up. No analytics. No tracking. The app simply works for you. — WHO IT'S FOR — People who keep starting things and stopping. Anyone who wants to build a fitness habit, meditate daily, finally read more, learn a language, quit a vice, or prove to themselves they can finish something hard. Beginners who want a calm tracker — and athletes, creators and founders who want a clean streak app without gamification noise. — THE PROMISE — You don't need 100 habits. You need one — done 30 times. Pick yours. We'll handle the reminders, the streak, the journal, the milestones. Day 1 starts now. ## Rankings - #1,422,661 — Overall ## Similar extensions and apps - [30-Day Challenge: Streak](https://chrome-stats.com/d/id6762292264) - [Challenge Tracker: Thirtyfy](https://chrome-stats.com/d/id6753996053) - [30 for 30: Daily Skill Builder](https://chrome-stats.com/d/id6449875961) — 5.00 / 5 - [HabitSprint -30 Day Challenges](https://chrome-stats.com/d/id6758390842) - [30 Day Me](https://chrome-stats.com/d/id6755921080) — 5.00 / 5 - [30 Days Challenge with Adastra](https://chrome-stats.com/d/id6736471188) — 5.00 / 5 - [30-Day Reset: Habit Tracker](https://chrome-stats.com/d/id6757112131) — 5.00 / 5 - [Dare30 - Daily Habit Trackerm](https://chrome-stats.com/d/id6760480813) - [30 Day Challenge - LockIn30](https://chrome-stats.com/d/id6770272031) — 5.00 / 5 - [Habit Tracker: 30Day Challenge](https://chrome-stats.com/d/id6502933719) - [30 Days Self Care Challenge](https://chrome-stats.com/d/id6757768877) - [30DC: 30 Day Challenge](https://chrome-stats.com/d/id1530232033) — 4.50 / 5 --- Source: [Chrome-Stats](https://chrome-stats.com/d/id6770298918)
