My One Rule: Habit Tracker
Build one habit that sticks
$0.99 · Designed for iPad. Not verified for macOS.
One rule. One tap a day. Build a streak that lasts, now also in Spanish and on Apple Watch.
My One Rule helps you build one habit at a time — no overwhelming checklists, just a single daily commitment you can actually keep.
Pick your one rule. Check in each day with a tap: Kept or Slipped. Watch your streak grow, right from your Home Screen or Lock Screen widget, or from your Apple Watch — no need to even open the app.
• Rest days — choose which days your rule applies to, so days off don't break your streak.
• Grace Tokens — earn a second chance at key milestones. Slip once, and your streak survives.
• Milestones — from your first spark to a full year unbroken, every step is worth celebrating.
• Widgets — Home Screen and Lock Screen widgets let you check in without opening the app.
• Apple Watch — check in from your wrist with the Watch app and complication.
• Slip notes — jot down what got in the way, privately, and learn from it.
• iCloud sync — your progress follows you across your devices.
Discipline isn't about doing everything. It's about doing the one thing, every day.
