Time you
can see.
A coloured wedge shrinks as the minutes run down. Everyone in the room reads it at a glance — no numbers, no arithmetic, nobody asking how long is left.

Why it feels right
The calm of an analog timer, with a feel of its own.
See it shrink
A wedge retracts to zero so remaining time is obvious at a glance — for focus, for kids, and for anyone who thinks better when time is visible.
Tactile dialing
Drag the dial or twist the knob and it ratchets, click by click. Flick it and it spins down to a stop; hit either end and you feel the thud.
Fifteen faces
From a classic charcoal timer to turned walnut, a dot-matrix LCD, a humming neon tube, an aurora and a party cake that bursts into confetti.
Every face sounds different
Walnut knocks, glass rings, the LCD clicks like a watch button. At zero it shakes, rings and buzzes, like a kitchen timer. Sound and haptics switch separately.
On the Lock Screen
The countdown lives on in the Dynamic Island and the Lock Screen, and keeps real time with the app closed. Pause or cancel without unlocking.
Private & offline
No account, no tracking, no data collected. Everything runs on your device. Pay once, keep it.
Fifteen faces
Each with its own character.
Made for
Wherever "how much longer?" comes up.
Help & support
Questions? We're one tap away.
What is a visual timer?
A visual timer shows time as a shrinking coloured area instead of digits, so you can see how much time is left at a glance. Otso brings that idea to iPhone, iPad, Mac and Apple Watch — a wedge retracts to zero across fifteen hand-made faces.
Which devices does Otso run on?
iPhone and iPad with iOS 18 or later, Mac with macOS 15 or later, and Apple Watch with watchOS 10 or later. One purchase covers all of them.
Does Otso work on Apple Watch?
Yes. All fifteen faces are on the watch. Turn the Digital Crown to set the time, tap to start, swipe sideways to change face and swipe up for settings. The watch app runs on its own — your iPhone does not need to be nearby.
Is there a Mac version?
Yes. On the Mac the dial is a small floating desk timer, with a wedge in the menu bar. Twist or circle two fingers on the trackpad to dial, and swipe with two fingers to change face. It's included in the same purchase.
Can I see the countdown on the Lock Screen?
Yes. On iPhone the countdown carries on in the Dynamic Island and on the Lock Screen, drawn as the face you picked, and you can pause or cancel it from there.
How do I set the timer?
Drag anywhere on the dial (or twist the knob on faces that have one) to set the minutes, then tap to start. Tap again to pause or carry on. On Apple Watch, turn the Digital Crown; on the Mac, twist two fingers on the trackpad.
How do I change the face or open settings?
Swipe sideways in the space beside the dial to change face, and swipe up for settings. Or press and hold the dial to lean back into a desk of faces. Settings cover the dial length, direction, what happens at zero, and every sound and haptic.
How long can the timer run?
Pick a dial of 5, 10, 15, 30, 60 or 120 minutes. Short dials give you finer steps; the 120-minute dial covers exams and long work blocks.
Is a visual timer good for ADHD and focus?
Many people with ADHD — and anyone doing focus or Pomodoro sessions — find a shrinking visual countdown easier to grasp than numbers. It makes time concrete, eases transitions, and cuts down on clock-watching. Read more.
Is it good for kids and classrooms?
Yes. A visible countdown helps children understand "how much longer" without reading a clock — great for routines, screen-time limits, homework, brushing teeth, and calm transitions.
How is this different from a physical Time Timer?
Same at-a-glance idea, but on the devices you already have — fifteen faces, real haptics, clockwise or counter-clockwise, a Lock Screen countdown, and it keeps accurate time with the app closed. The history of the idea.
Does it work offline? What about my data?
Everything runs on your device with no internet required. There's no account, no tracking, and no data collected of any kind. See our privacy policy.
How much does it cost?
A one-time €0.99 / $0.99 for iPhone, iPad, Mac and Apple Watch — no subscription, no ads, no in-app purchases, no account.
