Time to get healthy: three fitness apps for Apple Watch
Thanks to its ability to tap you on the wrist - something known as haptic feedback - Apple Watch is being talked up as a watershed moment for fitness apps

Taking a yoga session via a smartphone app makes little sense, but on a smartwatch, it almost works. FitStar Yoga takes you through a customisable routine, with a simple graphic showing you exactly how to strike a pose, and how many more seconds you need to hold it for. It's a great idea and a welcome change from the plethora of running apps. There's only one problem: glancing at a watch while doing downward dog could bring you crashing to the ground.

If you're counting calories, you need to log them into your body as well as out. A popular phone app, LifeSum is surprisingly minimalist; its main screen displays how many calories you have left to burn that day, how far you are towards your exercise goal and how much water you've drunk. Adding a glass of water is done with a simple tap on the watch, while its frequent reminders and advice are useful for staying motivated.
