Your phone's clock can drift. Tick calibrates to NTP or a chosen site and gives a millisecond countdown with a strong alert — act at the right instant. No automation. Tick — knowing exactly when "now" is, down to the millisecond. Your phone's clock can drift by several seconds. When a sale, a drop, or a livestream opens, "you thought it was time but the platform hadn't opened yet" costs you. Tick calibrates your time, then gives you a clear millisecond countdown. CALIBRATE FIRST, THEN COUNT DOWN · NTP standard time: align to atomic-grade time in one tap, and see how many milliseconds your phone is off · Website sync: read the time returned by a website you choose, to align to "that platform's clock" · Once calibrated, every countdown uses the corrected reference time A MILLISECOND COUNTDOWN YOU CAN READ · Set a target moment; a big countdown ticks to 0.001s in the final minute · Live on the Dynamic Island / Lock Screen — no need to stare at the app · Strong haptics + a notification right before zero · Floating millisecond window (advanced): stays on top even after you switch apps TIME ONLY — NEVER PURCHASING · Tick only provides accurate time and countdown reminders · It does not participate in, act on behalf of, or automate any purchase or checkout · No account, no ads, no social TICK PRO (one-time purchase, yours forever) · Unlimited countdowns: save as many target moments as you like · All color themes: light up the Island and Lock Screen · Support an indie developer: no subscription, no ads Catching the moment starts with getting the time right.
