Pre-release

FocusOne, one promise to keep.

Choose one habit, mark it done today, and keep your streak visible. FocusOne helps you keep one thing at a time, with no account, no social feed, and no unnecessary screen.

See how it works

Pick one thing

Many habit apps start simple, then become dashboards: many routines, many charts, stacked goals, and notification overload.

When you try to track everything, you often stop tracking anything.

FocusOne takes the opposite path: one active habit, one clear action, immediate feedback.

Pick a simple routine and validate it daily in one gesture. The app helps you keep momentum without taking over your day.

Keep it visible

Core markers stay available without turning the app into a dashboard.

One active habit

Pick one routine, mark today, keep the streak visible.

The first decision stays intentionally simple: one thing to keep, visible enough to come back tomorrow without opening a full dashboard.

One daily gesture

Open, check, move on.

Tracking stays quick, even on busy days.

A motivating streak

A simple signal to keep your momentum.

See your consistency and recover quickly when needed.

Light reminders

One or two reminders, not a notification storm.

Enough not to forget, without turning your phone into noise.

Day boundary adapted to your rhythm

Your day does not always end at midnight.

Define your day start so your streak reflects real life.

Useful widgets

Keep your routine visible at a glance.

Track your goal from home or lock screen.

Why only one habit?

Most habit apps make it easy to track too many goals. FocusOne takes the opposite path: one active habit, less dispersion, one clear action for today.

Pick

One simple routine, clear enough to know what counts today.

A quick check when it is done, without reopening a goal dashboard.

To avoid

No social feed, no public ranking, no external pressure. Your streak stays yours.

Privacy

Privacy policy — EN

Privacy Policy

FocusOne does not collect any personally identifiable information.

Your active habit and daily check-ins are stored locally on your iPhone using Core Data. If iCloud is enabled on your device, this data is also synced to your other Apple devices via iCloud — without going through any third-party server.

A few preferences are kept locally in iPhone system storage: onboarding state, notification preferences, subscription status, and trial start date. This data stays on the device.

When you use the home screen widgets, a limited snapshot of your data is shared between the app and the widget extension through a local App Group managed by iOS.

If you enable daily reminders, FocusOne schedules local notifications on your iPhone. No remote push notifications are used.

If you subscribe to FocusOne Premium — yearly subscription or lifetime access — Apple handles the transaction through the App Store. FocusOne does not receive or store payment information. Only the purchase state is kept locally.

FocusOne includes no tracking, no advertising, and no third-party SDKs such as Firebase, Amplitude, or Mixpanel.

To delete your data, disable iCloud sync for FocusOne in Settings → [your name] → iCloud, then delete the app from your iPhone.

FocusOne is not intended for children under 13.

For any question, the FocusOne page remains the contact point.
