Qwestr is a weird, powerful, productivity game. It can most succinctly be described as: ¼ to-dolist. ¼ graphic novel. ¼ item based rpg. ¼ mini-games. At its core, Qwestr is a standard to-do list app, it's familiar. You enter tasks to do at the top and you mark them done by swiping them to the right.
