Since iPadOS / iOS 13, if you use more than one language or keyboard on your device, then it becomes possible to select a preferred language for the app’s calendar and clock in Settings > PhotoFrame > Language.
The PDF vectors of the clock faces for modifications are accessible in Files > On My Device > PhotoFrame > Clock Faces, or from Finder (iTunes) File Sharing.
An optional auto-renewing monthly subscription is available which adds a bonus option Random for colour settings.
Your account will be charged for renewal within 24 hours prior to the end of the current period.
You can manage and cancel your subscriptions by going to your account settings on the App Store after purchase.
