While the basic functionality of Classtime is quite similar to many others (questions of different types, real-time responses and scoring, analytics) , it has a unique feature that immediately spices up your lessons. It's group quizzes, or collaborative challenges. Students answer questions to get a picture revealed or story build, and recently the endangered species rescue mission was added. It's possible to work with devices individually or in pairs - in any way it's the service setup that promotes collaboration and group work. It's so much more responsibility and engagement in the classroom, and the team work is thriving. Another thing I love about this service - it's that they are constantly updating and creating better user experience. The latest addition of a team challenge offers perfect opportunity to promote environment awareness.

My two favorite features are all the tech types they offer and the mechanisms they have for engaging students. They have puzzles that one can use to predict with evidence, a game where students can "save" endangered species, and various animations.

I love so many things about Classtime--I've used it in the classroom for multiple years now and love how I can quickly utilize question sets to rapidly gather data. I can usually complete a set with students in just a few minutes, which makes differentiation a snap. Classtime's Collaborative Challenges (available for individual purchase or by purchasing a premium account) are well worth the money, and take the idea of classroom competition and flip it on it's head. Instead of a zero-sum game, Collaborative challenges force students to work together to hit targets to achieve certain animations (building bridges, powering up robots, etc). It's a refreshing twist. Classtime's employees are also super responsive to teachers and often will consult with users to get quality feedback for future developments.
