Getting started
- Tap the ring in the middle and pick the time the sale opens. You choose hours and minutes; a time that has passed rolls to tomorrow.
- Pick the booking site in the row below. Sources are grouped by region and searchable.
- Tap Start. The ring fills and the countdown appears in the Dynamic Island.
- Haptics begin at the lead time you set. They arrive even while you are in another app.
Common questions
My accuracy is worse than ±100ms
A long round trip to the server you picked means a wider error bar. Tap the accuracy tile to see the network latency. Switching between Wi-Fi and cellular usually changes it. Picking a standard-time server such as NIST or NPL normally brings it into single-digit milliseconds.
The buzz feels late
The haptic is scheduled for exactly zero. What you are feeling is your own reaction: it usually takes 150 to 250ms between sensing the buzz and your finger landing. Measure that in practice mode and tap Use as lead compensation, and the haptic fires that much earlier.
No haptics while I am in another app
The whole pattern is handed to the Taptic Engine in advance, so it fires with sound off too. What does stop it is force-quitting Atto from the app switcher. Leave it running while a countdown is armed.
I do not see the Dynamic Island
Check Settings, Atto, Live Activities. The island appears on iPhone 14 Pro and later; on other models the countdown shows as a Lock Screen card instead.
The site I need is not listed
Open the time source screen, choose Custom and type the address. Any server that returns a Date header works.
I lost my Atto Pro purchase
Scroll to the ATTO PRO section in Settings and tap Restore Purchase to pull it back from the same Apple Account.
Notifications cover the queue page
iOS does not let one app suppress another app's notifications. Turn on a Focus from Control Centre, or enable Settings, Accessibility, Guided Access and triple-click the side button to block banners outright.
Requirements
iOS 17.0 or later, iPhone. English, 한국어, 日本語.
