OnTimer

OnTimer is an iOS app that helps you never be late for a meeting by sending simple, reliable alerts before your calendar events.

Send reminders before each meeting, using the alert time you choose.

OnTimer does not create, edit, or delete events in your Google Calendar.

You can disconnect your Google Account from within the app at any time, which immediately stops all access.
