Do ① Thing
One habit. One day. Repeat.
$1.99
Your habit, your secret — the app doesn't ask and doesn't tell. Six themes, emoji notes, and a streak that's quietly rooting for you.
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
• Reset — change your mind
Watch your streak grow. See weeks and months at a glance in a clean monthly 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, iPad + APPLE WATCH
Check in from your wrist with a single tap. The iPad layout gives each day room to breathe — larger cells, centered icons, the full month at a glance. iCloud keeps everything in sync across all your devices automatically.
SIX THEMES
Choose the look that matches your energy:
• Jewel — bold and vibrant
• Mindful — calm and cool
• Focus — warm and grounded
• Sunset — soft golds and rose
• Ocean — deep teals and blue
• Midnight — dark, rich, and easy on the eyes
EMOJI DAY NOTES
Add a quick emoji to any day as a private decorator — a small reminder of how that day actually felt. Separate from your check-in state, never used in stats.
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
Purchase once, yours forever. No subscriptions. No upsells.
One thing. Every day. That's the whole idea.
Ratings & Reviews
Sync you can see.
If iCloud hiccups, a small pill at the top now says so and the app keeps trying in the background. Days that haven't arrived yet show an orange ! instead of looking unset, and tapping one retries.
On Apple Watch, tap "Did it!", "Partially" or "Didn't do it" on a reminder and it counts right away — no second tap.
On iPad, the calendar now shows when you launch in landscape.
Smaller polish: the emoji row stays put and unlocks once a day has a state, Today lives in the toolbar and jumps to the current month, and the keyboard no longer makes the card jump.
