Fit HIIT by Healthista (£2.99, itunes; £3.59, Google Play)

Want to get in shape, but short on time? Based on High Intensity Interval Training (HIIT), this app allows you to input how long you have to exercise, and creates a specific workout for you – and you’ll never get the same one twice! With each move explained vocally as you go, it’s like having a personal trainer in your pocket!
