To-Do List Buddy

To-Do List Buddy (ogarniak in Poland) is a to-do list with consequences. Plan tasks with a deadline and a reminder. Finish them on time and your pet grows; miss one and it loses a heart (never more than one a day, and you can earn hearts back with the built-in Pomodoro timer). It also has habits with a history grid, a bucket list, voice input in English and Polish, and a lock-screen widget. Everything stays on your phone, sign-in is optional. iPhone and Android, free trial.
