Disappointed with this app (and the isitup). The way it sounds, you test yourself by doing a max number of pushups, and the app provides a work-out to follow to increase them. In theory, that sounds good - but the app is basically built for somebody who can only do a couple pushups to start. The problem is that it is a cookie cutter approach. It doesnt matter if you can do 10 pushups, or 100 pushups, the workout is the same. You do a set of 9, then 10, then 8, then 8, and then your last set is to max out again, which should be "at least 10." Again, the app is probably great if you can only do a few pushups, but if you can already do 20 or 25, I dont think this will help. To make it more challenging, I even did the program with the PerfectPushups, but I still found it too easy.
