Update Needed!!! – Flow Test Calculator Review

I love this app, however, since the Apple update every time I use it (multiple times a day) it freezes up after one calculation. You have to restart the phone in order to reset this app. It is becoming very frustrating to say the least! Maybe an update is in order? I would give it a 4 star rating but the last few days I would drop that to a 1or 2 star!!! HELP!!
