I've released a bugfix update for Wicca Plus today, this is version 4.0.1.
Fixed a bug preventing importing files from Dropbox.
Fixed a bug that caused the app to reset a custom book name.
Also improved behavior for Edit Core Entries (unlocked via in-app purchase).
Finally, I added an entry to the Sabbats section which lists Solar and Lunar charts for the current and next year. Basically it lists all the full and new moons, and the solstices and equinoxes, giving dates and times in your local time zone.
The free version, Liber Umbrarum et Lux, has also been updated. Mostly minor updates to bring it up to date with modern iOS 10 coding practices.
I've got some more ideas brewing for Wicca Plus 4.1 which I hope to have out in the next few months. First though I need to bring my other two apps (Overlord! and Tick'd Off) up to date for iOS 10.
