Read the developer’s release notes
DO NOT UPDATE if you have older devices that cannot get the update (iPhone 7 or earlier, iPad mini 4 or earlier, iPad Air 2 or earlier, or iPad 4th gen or earlier). If all your devices can run iOS/iPad OS 16+ or are Apple Silicon macs or are Apple Vision Pro, then you’re good to update. Interoperability with our original version is still being worked out and we are awaiting feedback from Apple to fix. The older version of the app still works fine on all devices, however, we are being forced by Apple to issue an update in order to keep the older version of the app in the store on older devices.
This new version is completely re-written to use modern technologies and frameworks (which now requires a minimum of iOS 16 for the new version, however, older devices can still download our old version which we would like to get working with the new app!)
New app icon and design upgrades which are deliciously clean and clear on any screen size! No more black bars or fuzzy images on retina devic
