Normally I’m not one to review apps, but this one has all but saved my life. So I recently switched to android and I was annoyed that all the alarm sounds are so damn quiet, and honestly I sleep like a dead girl. I found this app while trying to find an alarm app. I looked through the comments saw the words “Solve a math problem” and got curious. So this works like any other alarm, set it to the time you want and it works perfectly. The difference? How you turn off the alarm. Say goodbye to hitting snooze until you’re late. It won’t let you [well you could keep it on normal setting], but there are many ways to turn off the alarm. You can take a picture, scan a bar code, shake it, or solve a math problem. Now I know the math thing sounds pretty dumb but it will not stop ringing until you solve a set amount. You can set the difficulty ranging from simple 10+12 math to much more difficult math such as 1012×4721+356-10. Not only that, you can set it to be one problem you complete up to 6 you have to complete. It will not, unless the phone dies, stop going off unless you do them. For someone like me, who is terrible at math and also smacks the snooze button while half awake, this is great. Annoying as heck, but it wakes me up, so it’s amazing. So if you have issues trying to wake up in the morning, this is for you!
