Add this!

This is the best alarm is so loud. I really like that you can make it sound through the speaker. I use my headphones to hear rain sounds cause it helps me sleep. The headphones comes out of my ear at night so is nice to know that I will hear the alarm. I just hope that you will add the ability to use the alarm without having to hit bedtime every time. Sometimes I use the alarm just to wake me up if I fall asleep on my chair while watching TV. So please if you could add that on the next update. Thank you for making this awesome alarm.

Information is power!

I like knowing that sleeping 8 and a half hours is better for me usually. I can see the data! And having the alarm go off within a period rather than at a set time really makes all the difference. I feel much more in control!

By keeping your bedtime, wake-up time, sleep time, and pre-sleep habits (eating, bathing, exercising, stretching, etc.) stable, you can wake up feeling refreshed and energized during the day.Please share this experience with your friends.
