FAQ
Common questions
Why don't calendar reminders wake you up?
Because they are notifications. Silent Mode mutes notification sounds, Focus can hide the banner entirely, and the alert disappears after a second. Alarms are a separate category that overrides both.
What is the best calendar alarm app for iPhone?
Pealo if you keep several calendars that change weekly, since it connects Google, Outlook and iCloud at once and arms alarms automatically. The built-in Clock app is enough for a fixed schedule.
Can an app set alarms from my calendar automatically?
Yes. Pealo reads the calendars you connect and schedules a real system alarm before each event, updating them when meetings move or are cancelled.
Do alarms ring in Silent Mode and Focus?
Yes. Both iOS and Android let alarms through Silent Mode, Focus and Do Not Disturb. That is the difference between an alarm and a reminder.
