Calerto turns your calendar into alarms you actually can't sleep through. Instead of a notification you swipe away, you get full-screen meeting alerts, with custom prep time for each meeting. It syncs with Apple and Google Calendar, shows a menu bar countdown to what's next, and can launch automatically at login (you can turn that off anytime). Pause an alarm without losing it. With Pro, you can auto-alarm your whole week. Your calendar data never leaves your device. Never be late again.
