Overall, its a nice app, but it feels a little bit like its in beta phase. I am sure it will improve.
Problems:
1) it has a warm up calculator, but its obscure. I used the app for over a month while being annoyed thinking it didnt have one. Once you know where it is, its very useful.
2) doesnt seem to be a way to share data across devices. Id like to be able to enter my workout data on my phone, and view it later on my iPad. Is that a lot to ask? Not for a $5 app its not.
3) you are forced to view your history in the form of a hard to read graph. The graph is hard to read on an iPhone, and I would prefer to just see the numbers.
4) there is no way to keep notes. Again, not much to ask in a $5 app.
5) app always forgets whether its the a workout or b workout.
