## What is ZeroHour?

ZeroHour is a precision time toolkit built for moments where every millisecond counts: NTP clock sync, Dynamic Island countdown, floating PiP timer, and a sales-day calendar.

MILLISECOND NTP SYNC
Sync your clock to network time with millisecond accuracy. Never lose a flash sale, ticket drop, or midnight launch again.

DYNAMIC ISLAND & FLOATING TIMER
Keep your countdown alive on the Dynamic Island while using other apps, or drag the PiP timer anywhere on screen.

SALES CALENDAR
Track big sale events and midnight drops with automatic reminders.

FULL TIMER TOOLKIT
Stopwatch (millisecond display), countdown, count-up, Pomodoro, and scheduled reminders — for study, workouts, cooking and work.

Download ZeroHour and make every second yours.

NEW: Work Pep Talker
Need a push to start the day? Work Pep Talker drops you an encouraging line on hourly reminders or when a countdown ends. Pair it with focus timers — made for the 9-to-5 grind. Enable it in Settings.
