Rezzly is a gamification platform for the classroom.
Students interact with Rezzly through the completion of quests. There are currently 20,000 quests available from other teachers, and you can create your own. The platform takes care of all the nitty gritty data collection for you.
The onboarding for students has a pretty steep usage curve, I wish the site would support Google and Microsoft logins to make it easier to use, but I assume the target student audience is of higher grades.
Sign-up does require a credit card, which may be a cause of hesitation for some teachers.
