Fantastic alarm app I've been using this app since day one. For a while it didn't seem to do much, because I was using it wrong. Now I set it, even for only 3 cycles if I can't sleep longer, and I use its calculations to set the built in alarm for reinforcement. Works a treat! Even if only for a few hours. I wake up quite easier than I used to.
Beta Tester here! I've been using this app for weeks and I have to say, it made this skeptic a believer in sleep cycles. It really made me more concious of when to get to bed. I also love the annoyance sound pack. I don't have music on my phone so it works best for me.
Fixed crashing issue when trying to set an alarm on the Bed Time tab.
