List King

List King is an easy-to-use todo list app that lets you sort your tasks and checklists nicely according to colored areas. You can gray out completed tasks with a simple click, but you can also reactivate them at any time or delete them completely. With a normal checklist, such as a shopping or travel list, you want to tick off the things to be packed, but mark them as “still to be done” on the next trip or the next shopping tour. One click and the tasks appear again as unfinished items on the list. To keep an overview, you simply show or hide all completed tasks in the respective list. You can also search within lists, just swipe down. Create, edit, delete, duplicate or move your lists and tasks as you like. With this intuitive to-do app, there are no limits to your creativity. List King supports iCloud sharing. You can also print all lists at any time or export them as PDF documents. Of course, this app is completely ad-free and there are no in-app purchases and subscriptions. Charge once, use always. ;-)
