I wrote this app because friends and I often do challenges like "100 pull-ups in the shortest amount of time" or "you have 1 h to do as many pull-ups as possible". Paper and pen are not really comfortable if you train outside where it is windy (and maybe you even have some chalk on your hands).
This app will make it easy to track progress. Just a few taps and your progress is added to the log.
You can also use this app to track a certain exercise over a period of several days or weeks. You can track how much pull-ups you can do in a month for example.
In future releases it will be possible to track several excercises at once.
