One number per habit: days since you last showed up. Keep it at zero.
Honest widgets, gold weeks, and a card that knows exactly what to say.
One number per habit: how many days since you last showed up.
Keep it at zero. That’s the whole game.
Day Zero is accountability without the noise — no streak anxiety, no social feeds, no accounts. Just a big honest number that goes green when you show up and red when you don’t, on your Home Screen where you can’t ignore it.
THE RITUAL
Open to Today: what’s owed, what’s done, one tap to settle up. Every habit gets its own board — the number, the week’s dots, and a line of copy with actual personality.
DAILY OR SCHEDULED
Run flexible targets (4× a week) or pin specific weekdays. Planned rest days get calm recovery copy instead of guilt — and if your weekly goal is mathematically at risk, the card says so out loud.
GOLD WEEKS
Hit your weekly target and everything turns gold. Win EVERY habit’s week and you’ve earned a Perfect Week — with a shareable gold poster. Sharing is earned here, not ambient.
WIDGETS THAT WORK
Log with one tap from the Home Screen or Lock Screen. A single-habit widget in every size, plus an all-habits overview that goes gold on perfect weeks.
LIFE HAPPENS
Pause any habit: the number stays honest, the guilt switches off, and a gentle check-in asks when you’re ready. Logging anything brings you back instantly.
A VOICE, NOT A DASHBOARD
Hundreds of hand-written lines that rotate daily and never repeat until the pool runs dry. Optionally, let on-device Apple Intelligence write fresh lines from your real context — your gap, your week, your goal. Tap any card to flip it: your “why” waits on the back in a gold frame.
PRIVATE BY ARCHITECTURE
No accounts. No analytics. No servers. Everything lives on your phone.
Habits: running, reading, meditation, stretching, strength, swimming, cycling, rowing — or build your own with an 84-icon library.
