A free program for Android, by Jikan Software.

Developed by Jikan Software, Notepad is a handy app for users who want a more digital approach to note-taking (or doodling). With this free app, you can write everything under the sun, from shopping lists to drafts of your written assignments. You can even create a class schedule. 

Notepad offers a backup feature should a data loss occur as well as a restore feature if you accidentally deleted a note. If you’re a student, the app’s sharing feature comes in handy in case you need to lend your notes to someone who missed class. Notepad is compatible with devices with Android version 4.4 and newer.
