Great Alarm

I love this alarm. I use it every night. I wake up refreshed every morning. It detects your body movement and finds the shallowest point of the sleep cycle near the set alarm time within the time interval you set, say 30 min, 15 min, etc. Since it finds the point when you are at the shallowest or almost awake point, when it wakes you up, you are awake and not groggy. Since we all go through deep-shallow cycle throughout the night, I can find the shallow point in your sleep no matter how long you you plan to sleep, 7 hours, 5 hours, or even 3 hours. It is easy to set. Set the alarm time, interval of how long you want the program to search for the most desirable wake-up time (0-30 min), snooze time interval (ex. 9 min), what tone or music you want to wake up to. You can also play different soundscape or your favorite music to fall sleep in ( in the full app only). Nice thing is that you don't have to worry about how your iPhone's sound is set. Even if your iPhone is in the silent mode, it will play the alarm setting you set within the program. After each night you use this app, you can view the color coded graph to have a complete glance at how well you slept (REM, shallow, awake, etc). Gives you a sleep efficiency score. It's right on your phone, so you don't have to carry another alarm device. I do recommend to connect your iPhone to the charger while you use this app overnight. You set it on your bed, so make sure you have a long enough charging cable.

Sleep Perfection

I am a huge fan of this app and have strongly encouraged others to use it. I started out with the free version, but really wanted be benefit of tracking my sleep over a longer period of time than just a week, which the paid version offers. I find that I feel it is fairly close to accurate, as the sleep efficiency score often lines right up with my experience of my night and I can use that to reflect on things I can change in order to improve my sleep hygiene. Additionally, the alarm feature world great although it's usually fighting against my nature to force myself to continue to sleep, which always turns out to be a bad idea. If it's waking you up before the alarm time, just get up! You will feel better the rest of the day for it, I promise. The sounds in the app are great. Of course I always want more, but it didn't cost much and I'm happy with what I have and that it syncs up with my argus app for exercise tracking and so on.

Please fix the headphone issue!!

I've used this app for over a year now, and I love it! But, I live in a very full household, and sometimes the only way I can get a good night sleep is to use my noise-canceling headphones. In one of the updates, they did something to the app that now causes the volume of my headphones to go to full blast when the alarm turns on. This app is supposed to gently wake you up when in a lighter phase of sleep, but there is nothing gentle about getting a sudden blast of music in your ears causing you to bolt out of bed as you frantically and still mostly asleep try to figure out what is happening, rip the headphones off of your head, and stumble around with your phone trying to either turn the volume down, or hold for 3 seconds to turn the alarm off. Not a very pleasant wake up. I would eagerly give this app a 5 star rating if they would fix that bug!!
