How it works
Three steps, then never again.
Connect your calendars
Google, Outlook and iCloud. Add as many accounts as you use.
Choose how early
Five minutes before, fifteen, an hour. Per calendar, or one rule for all.
Close the app
Pealo sets real system alarms. Events move, alarms move with them.
Inside the app
Three screens. That is the whole app.
Your day, armed
Every meeting with an alarm in front of it, and the next one counted down at the top.
On the Lock Screen
A live countdown to the next alarm, the calendar it came from, and one tap to skip it.
Every calendar you use
Pick which calendars show up and which ones are allowed to arm alarms on their own.
Google, Outlook and iCloud.
Connect as many accounts as you have. If the same meeting sits in two of them, Pealo rings once.
