OneGoodHabit: Habit Tracker

One small habit at a time. OneGoodHabit is a habit tracker built on what research says about how habits form. Tap a star each day, and watch a habit become automatic. • NEVER MISS TWICE Most trackers punish you for one bad day. In a 2009 UCL study, a single missed day didn't hurt habit formation. So in OneGoodHabit one missed day keeps your streak alive; only two in a row end it. A free streak freeze each month adds a safety net. • 66 DAYS TO AUTOMATIC The same study found daily habits took 66 days on average to become automatic (anywhere from 18 to 254). Each habit shows its own progress ring, so you can see it settling in. • MAKE A PLAN: "AFTER I…, I WILL…" Tie each habit to something you already do: "After I brush my teeth, I will read one page." Plans like this make you far more likely to follow through, and your reminder shows the plan. • START TINY Set the smallest version that still counts, like "1 push-up". On a hard day it still earns the star. • TAP FROM YOUR HOME SCREEN A free home-screen widget lets you tick off today's habits without opening the app. • FITS YOUR LIFE • Every day, chosen weekdays, or a few times a week • Done-or-not habits, or numbers like 10 pages or 8 glasses • Gentle reminders that skip habits you've already done • Night owl? Let your day end at 1–4 am • GitHub-style history grid; fix past days any time • Midnight and Paper themes • English, Español, Français, Deutsch, Português, हिन्दी • PRIVATE BY DESIGN No account, no tracking of your habits: they stay on your phone. • BETTER WITH FRIENDS Make a circle with up to 10 friends. Choose which habits to share, see each other's progress, cheer friends who are done and nudge those who aren't, and race on a weekly leaderboard. Sign in with Google or Apple; friends never see your email. • FREE, OR PRO Free: 3 habits with every research feature, the widget and Friends, with a small banner ad. Pro is a monthly or yearly subscription (7-day free trial on yearly): no ads, unlimited habits, full-year reports, more circles, per-weekday reminders and export. Cancel any time.
