I would highly encourage anyone who is still using Poker Journal to find an alternative.
Apple has recently made it clear that apps that have not be updated for 64 bit compatibility will not work in future versions of iOS. (I'm presuming iOS 11)

I think it's fair to assume that the app will not be updated again. In that case, Poker Journal will go from an app that is outdated/buggy to one that is simply not compatible with iOS.
