UltraStop vs Tick

A high-performance stopwatch app designed for tasks requiring ultra-precise time measurement. It measures time down to milliseconds and microseconds with exceptional accuracy, making it perfect for experiments, sports, programming tests, and more. With an intuitive interface, anyone can effortlessly record precise timings.

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.
