It is so structured, to point them to assistance, independent of the teacher. And that is what we want to promote: student to student interaction using peer body talk, turn and talk, sharing, and all those things. ~ Dwight Barnes, 4th grade math teacher The dashboard is amazing. Insights are exactly the quick pieces of information a teacher would want at first glance. The grouping tab is really clean looking and is exactly what teachers and administrators want to see on a daily basis. Teachers could literally print that out and use it in their lesson plans when talking about flexible grouping. It does a great job of presenting the information in a simple way. ~ Josh Shaw, Tech Director The teacher dashboard is in a very clear format. I like that I can see in one place how each student in the class is progressing. The green/yellow/red color code is a great visual as well as the specific number within the box. It's helpful that I can hover over each concept and see the explanation of that standard. Overall great product! ~ Jennifer Auten, 2nd grade teacher Freckle - I love the videos! Instead of showing them just a paragraph write up, it's just like a teacher sitting there with them and going over it. I think Freckle is a great app for classes and for schools that have a time-sensitive schedule and it gives them instant feedback and data that can be used in class the next day. ~ Jabari Bush, 5th grade math teacher One of my students got a double digit + double digit problem and he had never done that before. He asked me and I quickly showed him. Next thing I knew he was asking me how to regroup and was doing 2 digit + 2 digit with regrouping, which was extremely impressive to me at this point. I did take a look at the dashboard. It is fantastic. I showed one of my administrators who is also our Math IST and she is beyond impressed. I've been telling a lot of people about it and will continue to do so! Thanks again for making what is now the most vital part of my math class. ~ Jane Alukonis, 1st grade math teacher Freckle is a good solution for our students and our teachers, especially working in an RTI model, teaching CCSS and addressing learning needs within a differentiated instructional model. ~ Emily Klug, 5th grade math ==QUESTIONS?

ReceptionRating · Positive reviews · Number of ratings

Clever Crazes holds the better App Store score, 4.2 against 3.3. That said, the two scores are not equally well evidenced: Freckle by Renaissance has 522 ratings behind it against 13, so its average is the more settled of the two. Written reviews complicate that: 40% of Freckle by Renaissance's written reviews are positive against 0% of Clever Crazes's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Freckle by Renaissance ships an update every 3 months, Clever Crazes every 2 weeks. The most recent releases landed on October 23, 2026 and October 24, 2026 respectively.
