Common questions
How do I set an alarm for 12:30 AM? This page already has 12:30 AM filled in — just tap Save. It rings at 12:30 AM as long as this tab (or its full-screen or floating window) stays open.
Will it go off if I close the tab? No — it's a browser alarm, so keep the tab open. Plug your phone in and tap Full screen for a large, always-on 12:30 AM alarm display.
Can I repeat it every day? Yes — open the alarm and choose Daily, or pick specific weekdays, to ring at 12:30 AM each day.
Counting a length of time rather than waiting for a clock time? Use the online timer instead — set it for a number of minutes and it rings when they are up. Given this time as 00:30 on a 24-hour clock? That's 00:30 in 12-hour time.
