Have a great day
After saving an appointment here, tap Add to Google Calendar. Check the details in Calendar, add alerts for 1 day and 1 hour before, then save the event.
Allow Google Calendar notifications on your phone. Try a test appointment a few minutes ahead to check that an alert arrives.
This planner cannot send alerts while closed. Google Calendar sends them after you save the event there. If you edit or remove an appointment here, update Calendar too.
Your appointments stay in this browser on this device. Export a backup before clearing browser data or changing phones.
Next, add it to Google Calendar to get phone alerts.
