A free program for Android, by Arpi Toth.

A simple to-do list app with a clean and intuitive user interface. It supports many options such as multiple lists and the option to set a due date. The lists can be sorted by name and/or date. You can also add a note to each task.

You can set a priority for each task, which will help you remember to do them. The app is completely offline, you don’t need to register, so if you lose your phone, you don’t lose your lists.

This app will work offline, it will not require any connection to the Internet to work.
