Okay. Doesn't always detect the pull up – Pull-Ups Workouts & Trainer Review

I like the other Runtastic Apps. But for some reason, this one is iffy on the sensing of my pull ups. I placed my iPhone 5s in my pants pocket and it sensed 50% of the pull ups that I did. Tried it again on a different day with the phone in my shirt pocket and it read 1 out of 8 pull ups.
