Been using the app for Im sure a month now. Still using because I am much preferring it to my phones alarm sounds. The gradual waking has been delightful, plus I knew I was not sleeping the optimal Amount of hours for myself. The charting showed me just how less sleep I was getting. Im still trying to meet my goal of 7 hours of sleep, bc Im consistently closer to 6. I most enjoy setting my clock and seeing right then how much sleep Ill get based on what time Im going to sleep. Meets my needs, and I find it cool! Good for setting 25-30 minute power naps too.
Complimentary apps for falling asleep to white noise or other sounds are nice too for nights I need them.
