Love the idea – Sleep Timer – Smart alarm Review

I love that the app tells me how much sleep I should be getting but I am having a hard time navigating the app. I tried using the build in alarm and it never went off, luckily I set another for back up. I also don't see a way to preview alarm sounds before you choose one. The app is a great idea and I look forward to using it.
