I have been using this great app since last season and it has worked fine. I tried it yesterday and two things happened: the first is that I have no numerals for the hours (only minutes appear) and so I had to do a manual start before leaving shore and secondly, the app shutdown about 10 minutes after the start and I had all the correct settings not to allow auto shutoff and the battery was fully charged. I am using an iPhone 5s. Back home I have deleted the version and reinstalled (both were the latest version) and now I have seen that the numerals are still hidden (I can hear the clicks when it rolls over the numerals but I can’t see them . Very disappointing.
