One - Do One Thing Today

One task per day—not another endless list. Plan tomorrow tonight, finish today with calm focus on iPhone, iPad, Watch, Mac, and widgets.

One priority. One day. Get it done.

One is a minimalist focus app built around a single daily ritual: choose tomorrow's most important task tonight, wake up with clarity, and complete it.

THE DAILY RITUAL • One task per day — no lists, projects, folders, or clutter • Set today's priority or plan tomorrow's before bed • Guided flow: Start Focus → Complete Today • Optional "why it matters" note for each day

STAY ON TRACK • Evening reminder: "What is tomorrow's one thing?" • Morning reminder shows today's task when delivered • Mid-day progress check-in and end-of-day nudges when you're still working • Yesterday rollover when last day's task needs closure • Home Screen, Lock Screen, Watch, and Mac widgets • Tap to complete from supported widgets and watch complications

LOOK BACK WITHOUT GUILT • History — search and filter past days • Calendar — month view with calm, neutral missed-day styling • Reflect — weekly, monthly, quarterly, and yearly prompts • Stats — focus days, completion rate, streaks, month and year charts

EVERYWHERE YOU WORK • iPhone and iPad with the same calm tab layout • Apple Watch today companion with guided completion • Mac sidebar app, menu bar quick actions, and desktop widget • Optional iCloud sync across your Apple devices

YOUR DATA, YOUR CHOICE • Works fully offline with on-device storage • Export your data anytime (JSON) • Delete all data from the app when you want • No account signup. No ads. No subscription.

One is a one-time purchase. Buy once, use on all your devices signed into the same Apple ID.
