An Indian student has invented an alarm clock that's a little... sadistic: every time you press the snooze button you get an electric shock! Fortunately, today's app is a little more gentle.

"Turbo Alarm" is an alarm clock that has a variety of ways to wake you up, without you returning to the snooze button every time. Why not be woken by your favorite song, or come out of your slumber slowly with a rising crescendo of sound. You'll find a setting so your phone mimics the sunrise, and there's even the option to make sure the alarm only stops ringing when you turn on your bedroom light.

Another useful little feature is that the app will indicate the weather at the time when you are to wake, in order to suggest how you should dress! Very practical.

∞ Loop

A loop could refer to any of the following: a flexible region in a protein’s secondary structure, a 1999 romantic comedy, a basic roller coaster inversion, one of the structures used to tie knots, or this beautiful app!

“∞ Loop” is a minimalistic puzzle game in which you have to make sure that there are no loose ends. Each section has either a curve, a straight line or a circle, and you have to join these up to make either one or multiple never-ending loops. It seems simple to start with, but it quickly becomes more complex.

The patterns in “∞ Loop” are often symmetrical and intricate. And as this app has no time limit nor leaderboards, it’s all about relaxation and personal satisfaction.

twelve

I can see why this app was a nominee at the 2015 International Mobile Game Awards for Best Meaningful Play - it’s a real brainteaser of a game!

“twelve” is a tiny puzzle game based on numbers in a grid that you move around, match and grow. Inspired by the concept of 2048, this app goes that step further as you only need to reach 12 (and the numbers go up by only one each time). It may sound easy, but the grid fills up quickly and you really need to think ahead…

There are four different levels of difficulty in “twelve”, your game saves automatically and you also have an ‘undo’ button. You can share your score with friends, unlock achievements and even hit the leaderboard if you can get a high enough score!
