I have had this app for several years now. I really like it except for O N E B I G F L A W! Since the beginning the precipitation has been off by a factor of +10x actual. We have rain 2night. Says in the 0700 time frame 335mm! It probably should 33.5mm if we are getting a deluge, or 3.35mm for a heavy rain over one hour. Your converter must be out of whack.
