Acuo
A calm flip-clock focus timer. Pick a duration, flip the clock, get to work. Acuo keeps a tidy on-device history of every focus session — plus Live Activities and Dynamic Island while you go.
A timer with a notebook attached
Flip-Clock Countdown
A tactile, distraction-free timer that's pleasant to glance at and impossible to misread. Pick a duration, hit start, let it count you down.
Live Activities & Dynamic Island
Your running session lives on the lock screen and in the Dynamic Island, with a self-ticking countdown you can see at a glance. Compact, expanded, and minimal — all supported.
Session Notes
Jot a quick note when the timer ends — while the context is still fresh. Capture what you actually got done, not what you planned to do.
Editable History
Browse past sessions in My Sessions. Tap to edit the date or note, swipe or use Edit to delete. Look back at where your time actually went.
Local-Only, Always
Your sessions live on your device. Nothing is uploaded, nothing is synced, nothing is shared. No accounts to create. No trackers. No streaks. No nagging.
Light, Dark & Localized
Pick Light, Dark, or System in Settings. The chameleon mascot adapts to both. Available in English, German, and Spanish.
Quiet by design
For people who already know how they work
Acuo is a single-purpose focus timer for people who already know how they want to work and just need a quiet, dependable timer to bracket their focus blocks — students, writers, designers, developers, makers, and anyone running their own version of Pomodoro, deep work, or timeboxing.
If you've been using a kitchen timer, a stopwatch app, or scribbling end times on a sticky note, Acuo is the upgrade that stays out of your way.
Built natively in SwiftUI with first-class support for Live Activities and the Dynamic Island. Every screen, every animation, every interaction is tuned to feel calm — never urgent.
It is not a habit tracker. It is not a to-do list. It does not gamify your focus or guilt you into longer sessions. It is a timer with a notebook attached.

Privacy Policy
This app ("Acuo") respects your privacy. This Privacy Policy explains how information is handled when you use the app.
1. Information We Collect
None. Acuo does not collect any personal data. There are no accounts to create, no email is requested, and no profile is built about you.
2. Where Your Data Lives
Every focus session, every note, and every setting is stored locally on your device. Nothing is uploaded to a server, nothing is synchronized to the cloud, and nothing is shared with third parties.
3. Analytics & Tracking
Acuo does not include analytics SDKs, advertising identifiers, or third-party trackers. We do not know how often you use the app, how long your sessions are, or what you write in your notes.
4. Third-Party Services
Acuo does not communicate with any third-party services. The only network activity from your device caused by the app is the App Store's own update checks, which are handled by iOS itself.
5. Children's Privacy
Acuo does not knowingly collect personal information from anyone, including children. Because nothing leaves your device, there is no profile to collect from in the first place.
6. Changes to This Policy
This Privacy Policy may be updated from time to time. Any changes will be reflected with an updated date on this page.
