Widgeridoo
Free (IAPs) FROM Sandro Pennis, noidentity.ch NEEDS iOS 15 or later
While most Home Screen customisation apps stick to one widget per widget, as it were, Widgeridoo has other ideas. It works on a simple block-based system: choose how many blocks your widget will occupy, then fill those blocks with widgets. That means you can combine, say, a calendar on the left with a to-do list on the right. Each combo widget can be tweaked with colours and styles, too. Best of all, your first four widgets are completely free.
