Do ① Thing
One habit. One day. Repeat.
$1.99
One thing. That's all.
Pick the single habit, ritual, or commitment that matters most to you today. Don't tell the app what it is — that part is private. Just check in: did you do it?
Do 1 Thing is a deliberately simple daily tracker. Four states, one tap a day:
Done — you did it
Almost — partial credit
Miss — didn't happen today
Watch your streak grow. Glance at your week. See the pattern of weeks and months across an infinite scrolling calendar. Get a quiet reminder at the time you choose, with a one-tap check-in directly from the notification — no need to even open the app.
PRIVACY BY DESIGN
The app never asks what your "one thing" is, and it never knows. Only your daily check-in states are saved — the meaning lives in your head, where it belongs. No accounts. No tracking. No analytics. No ads.
iPhone + APPLE WATCH
Check in from your wrist with a single tap. iCloud keeps everything in sync between your iPhone and Apple Watch automatically.
THREE PALETTES
Choose the look that matches your energy: Jewel (vibrant), Mindful (calm), or Focus (warm).
GENTLE STATS
A streak counter, a 7/30/90 day breakdown, weekly bars, and a rolling success rate. Enough to feel progress, not enough to obsess.
ONE-TIME PURCHASE
$0.99 once, yours forever. No subscriptions. No upsells.
One thing. Every day. That's the whole idea.

• Celebration overlays are now centered on screen so you actually see them.
