One thing.
That's all you need.
Endless to-do lists don't make you focused — they make you anxious. One Thing asks a single question each morning: what matters most today?
Private by design · No accounts · No ads · No tracking
What's your one thing?
Focus on one task that will make today feel meaningful.
“Let go of the second thing so the first can breathe.”
Everything you need. Nothing you don't.
Thoughtfully small. Every feature exists to protect your attention.
Just one thing
Set a single task each day. No lists to triage, no priorities to juggle — just the one thing that matters.
Focus timer
A calm Pomodoro timer that keeps running in the background, with procedurally-generated ambient sounds to help you go deep.
Forgiving streaks
Build momentum day by day. Streak Freeze quietly protects your run when life happens — one off day won't wipe out weeks.
Daily motivation
690 hand-crafted lines of encouragement — a fresh one every day, in the app and your morning notification. It never repeats.
Private by design
No accounts, no servers, no analytics. Your tasks and reflections live on your device and sync through your own iCloud.
Everywhere you focus
Home & Lock Screen widgets, a Live Activity for the timer, an Apple Watch app, and Siri Shortcuts — your one thing, always a glance away.
No lists. No overwhelm.
One Thing is built for anyone who needs to focus — especially people navigating ADHD or burnout recovery. Choosing one thing isn't doing less. It's doing what matters.
