Set a reminder in 1-hour increments. Do you find that a timer is not always the best option when you need to do something after a certain amount of time? This is where Remind Me may come in handy. A reminder can be set in 1-hour increments from your current time over a 10--hour period. There is also an option to delete existing reminders. *Reminders will be added to the default list in the Reminders app. If you do not have a default list, you will be prompted to add one.
