Hello Tim,
I'm terribly sorry to hear about the trouble you're having. We had to stop updates for this app many years ago but before doing that we spent two years or more notifying all our users that they needed to move off of the app and it would no longer be supported. If you have a backup prior to the iOS update we can help you with getting the database recovered.
Please send us an email at: support@appigo.com and we'll assist you with getting your data recovered and ported to the newer app.
Tim Schoolland
