A god send! – Runey Calculator - for Rune Factory Frontier Review

This app is the most helpful thing I’ve ever had with this game! But I’m so sad because I accidentally updated to iOS 11 and the app is no longer compatible. Please if you can, PLEASE update the app so we can continue using it! I can’t even downgrade from this loathsome update ?
