Have you ever put a calendar event/meeting in your diary, set it to “Remind me 1 hour before”, “Remind me 30 minutes before”, “Remind me 5 minutes before” and “Remind me at time of event”… and still somehow missed the event? Now you can set an alarm to tell you that your event/meeting etc is starting NOW.
It will ring an alarm when the event starts(or up to 3 minute before) even if your phone is on a Focus mode so you will never forgot the event/meeting.
