Wake you up after a desired amount of sleep?
A setting where you enter your desired amount of minimum sleep (eg8hrs) the alarm then wont go off until you’ve hit this target and then wakes you up at the next ‘optimal’ time. For mornings when you don’t have to get up for a specific time
Adding to this, I’d love the ability to set my desired amount of sleep in half hour increments. Currently, sleep goal setting only allow for one hour increments.
