The term you may be looking for is "gamification" - Duolingo uses gamification to encourage progress on learning a language, you are using it for encouraging staying focus on tasks. But if you say this is like Duolingo, people are going to think it is about learning languages and your marketing is going to be confusing.

thank you so much for the valuable feedback. you're absolutely right, I'll proceed with "gamification" from now on!
