Riddle O’Clock is an alarm for iPhone that rings even in silent mode and Focus. To finish it, you solve a short tap-only puzzle: math, a riddle or a memory sequence.
If you stop the alarm without solving, Wake Up Check backup alarms keep coming until you do. Solve it, or it keeps coming back.
It needs iOS 26 or later.
Why does Stop still work?
Apple requires the system Stop button on every alarm, and the app does not try to block it. What the app adds is Wake Up Check: if you stop without solving, more alarms follow.
What is Wake Up Check?
Backup alarms that are scheduled when you stop an alarm without solving the puzzle. By default they arrive 1 to 5 minutes later and continue until you solve a puzzle.
Does it ring in silent mode?
Yes. The alarm uses the system alarm service (AlarmKit), which rings through silent mode and Focus. Make sure you allowed alarm permission when the app asked. You can check it in Settings.
Why does the Lock Screen timer hide seconds?
iOS shows minutes only until the last minute, then shows seconds. That is how the system displays the countdown, not a setting in the app.
