Doesn't count pull ups – Runtastic Pull-Ups PRO Trainer Review

I do not understand how people can write this app five stars when it does not count the pull-ups that you do. Then it locks up when I'm trying to manually log the pull-ups by lifting the phone so then it over counts them. There is no way to edit the results,so now I have a record that I didn't really achieve.
