Atomic Exact Time
Calibrated clock and countdown
Free · In‑App Purchases
Prepare your next start with a calibrated clock, saved targets and shared countdowns. Now available in 15 languages.
See your device clock in context with Atomic Exact Time. Compare it with network time sources, view the measured offset and estimated uncertainty, and use a corrected clock display.
Start with the free clock and synchronization tools. The free version includes ads. Optional Pro plans remove ads and unlock precision targets, team countdowns, detailed accuracy reports, Theme Studio, timecode and export tools.
Prepare a start: choose an exact time or a duration, check calibration and notification permissions, and test the sound before starting. Save, edit, duplicate and reorder your frequent targets.
Share a team target through a link or QR code. Each participant uses their own device calibration. Participant attendance and location are not tracked.
Use world clocks, Studio Mode, accessibility preferences and a home-screen widget that shows the latest calibration. Choose from 15 interface languages.
Timing accuracy depends on network conditions, device behavior and measurement quality. Uncertainty is an estimate, not a guarantee. Keep the app open for the best countdown timing. Background notification delivery depends on the operating system.
Available Pro plans and localized prices are supplied by your store. Monthly and yearly subscriptions renew automatically until canceled in store account settings. A lifetime purchase is a single payment when offered. Restore Purchases is available. No app account is required.
