Thanks for directing me here, @Jacoby_Elderfun1!
Habitica is a video game/fantasy-themed app that you could also access from your computer. It helps you finish your everyday tasks, build good habits, and break bad ones! You get points and awesome prizes for checking off to-do list and routine items, as well as good habits, and you get health damage from not finishing your work that day, or for checking off a bad habit. The prizes are awesome, the layout is straightforward and easy to understand, and if you need help with anything, the community is AWESOME, well-moderated for family-friendliness, and super ready to help!
Habitica has helped me immensely with my work! This past semester for me has been more productive than most because of it! (We started using it during Christmas break.) I would HIGHY recommend it for EVERYONE
One downside: The app tends to get a lot of bugs and glitches, so sometimes that might impede your experience. But it doesn't happen everyday, and they have a little chat place where you can report bugs!
Here is a tiny little sneak peek of what the layout looks like. It's where you can create new habits/to-do stuff/routine items.
Rated Five Stars!
