AccurateClock vs Long Lasting Clock

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.

START FREE Use the Digital clock with the Midnight appearance. Adjust the size, show the date or seconds, and choose 12-hour or 24-hour time. MAKE IT YOURS WITH CLOCK PRO Clock Pro is an optional one-time purchase, not a subscription. Add the Flip and Focus clock styles, Paper and Night Red appearances, and your own text, background and colon colors. Choose another time zone and give its displayed location your own town and country name. Add a personal message with its own font, size and color. Save up to five color settings, five messages and five time zones to switch between. QUICK TO ADJUST Tap a quick control to select its size slider. Tap again to cycle through its choices, or touch and hold to open its menu. Lock the controls to prevent accidental changes. A short interactive guide helps you get started. AT YOUR PACE Keep the screen awake while the clock is open. Burn-In Protection gently moves the display over time; it does not guarantee against screen burn-in. Keeping the screen awake uses more battery. Your personal messages, saved places and clock preferences are stored on your device, not collected by the developer. No account, ads or tracking. GOOD TO KNOW The app must stay open to show the clock; system restrictions may apply. Locking the controls does not lock the device or prevent leaving the app. World time shows one selected time zone at a time, and a custom place name does not use your physical location. Editing current settings does not overwrite a saved preset. The clock works offline; purchases and restoration use Apple's services. There are no alarms, timers, widgets or system Lock Screen replacement.
