Just an Alarm Clock is exactly what it sounds like. It's a clock. With an alarm. That's all. You can customize the colors, and choose from several fonts for the clock as well as several alarm tone options. But that's it. No tracking the vernal equinox, no automatically waking you at local sunrise. It's just designed to be easy to use. Set the alarm for the time you want. Swipe anywhere on the screen to make the alarm stop ringing or tap the large alarm bell to snooze. Nothing tricky, because lets face it, you're still mostly asleep when you are trying to operate this thing. Some other things it doesn't include? No pop-up ads, no in-app purchases to unlock the number 7, no annoying quizzes to make you think when you're not even awake yet. It's Just an Alarm Clock. And its free.
