The relative reminders app.
Delay is the quick and easy app for setting reminders without the hassle of scheduling and managing alarms for set times.
Quickly jot a note to yourself, choose an icon and color, and specify how far into the future you would like to be reminded. You can choose reminder times from as soon as five minutes to as far out as three weeks. Swipe down to save and you are good to go.
When the specified time has passed, a notification will be delivered to your phone displaying your reminder message. No need to delete or clear out any expired reminders - Delay will take care of all that for you.
