Subtasks, repeats and sync with CalDAV or EteSync
The core of the app is list building. Subtasks can be nested to unlimited depth, and repeating tasks come with detailed options. You can tag, filter and search tasks, and location-based notifications fire when you arrive at or leave a place.
Storage is your choice. Lists stay local if you want, or sync with Google Tasks, CalDAV or EteSync. EteSync adds end-to-end encryption, and list sharing works when you sync through CalDAV or EteSync. Drag and drop manual sorting is listed for Google Tasks.
The store description adds a few more items: custom icons and colors for lists, hiding tasks until a later date, adding tasks to your calendar automatically, and creating tasks or list reminders through Tasker.
