Very easy to use

Great app, really easy to use and set your own preferences for length of work out, intensity and difficulty level. The videos showing the exercise are very useful and it has a count down clock and beep to let you know when to move on to the next exercise.

The fitness app I’ve been looking for

Stak is by far the simplest fitness app to use, and yet still offers me all the customisability I need. How is it FREE?! I love that I can add my own videos, and the chromecast capability makes it great to follow on TV when I workout at home. Would highly recommend!

Finally a solid exercise app

Good app that allows you to put a number of exercises together and move them to the order you want. Quick and simple to get on with custom exercises!
