Widgetsmith
Whereas iOS 14 introduced widgets that could be dragged to populate your Home Screens, this app allows you to go a lot further in customising the appearance and functionality of these widgets. Once you have set your widgets up they can then be added to your iOS collection and dragged into position as normal. You can enjoy some of the more basic widgetediting features for free, but you’ll need to invest in a monthly or annual subscription to unlock the various seasonal themes and extras.
