AccurateClock
Set your watch precisely.
Free · Designed for iPad. Not verified for macOS.
A clock that does the one thing iOS won't: shows the seconds, clearly. Sweep or tick. Synced to internet for high accuracy. Built for setting watches that hack.
Accurate Clock is a focused little app for setting other clocks precisely.
Why does this exist? iOS's stock Clock app deliberately doesn't show seconds, which makes it useless for the one task you really need a clock for: setting another clock right on the minute. Mechanical watches that "hack" — meaning the seconds hand stops when you pull the crown — are particularly painful to set without a visible second hand to wait on. Accurate Clock fills that gap.
WHAT YOU GET
• A clean analogue face with a clearly visible second hand. Toggle between smooth sweep and one-second tick.
• A digital readout showing HH:MM:SS plus a smaller two-digit hundredths counter, so you can see exactly when the minute starts.
• Time synchronised against Apple's public NTP server (time.apple.com) once per launch. The footer shows when it last synced and the round-trip uncertainty so you know how much to trust the displayed time.
• A world time picker covering 48 cities across 31 zones — the same set as Casio's classic AE-1200 — with sectioned UTC offsets and live DST awareness.
• System-aware light and dark modes. No accounts. No ads. No tracking. No data collected.
WHEN YOU WOULD USE IT
• Setting a mechanical or quartz watch precisely on the minute.
• Setting a quartz watch or wall clock and being annoyed that you can't see the seconds.
• Checking the time in another zone to help set a clock for a trip.
• Just enjoying watching a second hand sweep.
WHAT IT IS NOT
This isn't a stopwatch, an alarm, a world-clock complication, or anything else. There are no settings beyond sweep/tick and timezone. It is deliberately small.
