I am a stop and start kind of person and currently at a start point again. I found this app and was very happy that it was a free app. Kind of sad when the updates included costs for new routines. Having recently retired and not done a great job of taking care of myself, I needed something to get me back into exercising and helping improve my physical health. This app is great because I could choose from the original 20 exercises options that allowed me to do routines that have me sitting for the whole time or standing for the whole time. I especially like the standing routines because they can be done almost anywhere at any time. Just need to stop and do them. The feature that I like most about this app is how you can adjust the exercise and rest times. It's perfect for longer workouts at home and setting up shorter workouts for when you're on the go. I also appreciate the tracking feature for how many days in a row you have done your workouts, since I like to do things in my own time without being pushed by others; this feature is my own cheerleader, keeping me enthused about continuing. So far I've only used a handful of the routines and I'm working my way through more of them but again, I am very disappointed that this app also went the route of purchases new routines, but at least for now I can still use the original free routines. I had been telling everyone I know about it because of time settings, easy routines and FREEness. Now I have to recant some of my enthusiasm but as long as the free portions remain free I'll continue to excitedly tell others. Thnx for the app - :)
