The WidgetOne app allows you to create your own customisable widgets, store them in the app and add them to your home screen.
If youre running iOS 16, you can add a simple widget "WO" to your lock screen to launch the WidgetOne app through it.
The ability to create widgets is paid. You can choose one of the types of paid non-renewable subscriptions - for a month, for three months and for a year.
