Before I got this app I was an extremely deep sleeper and it took me way too long to wake up. Now, most days I wake up before my alarm. It's an amazing app and the options that they have for how to turn your alarm off make it a thousand times better. My only issue is that there's one alarm sound that plays. They have options, but I chose the random option. For the first week or so it worked but after that it just played the default alarm. If this was fixed/improved the app would be perfect.
