★★★★★ maria maria · Jun 27, 2022

Superb!!! I would like to ask you to incorporate visible jumps made by the students for example with painting themselves with their fingers and that can be erased. Thank you so much.

★★★★☆ Tyler James · Jan 28, 2023

I love how you can do time tables but why I rate it a four is because there might be ads I wish I could give it a 4.5 but so yeah

★★★★★ Jennifer A · Jan 20, 2021
