Ratings and reviews

I'm a dyscalic adult trying to relearn my math skills. I'm really impressed with the detail it goes into explaining the concepts. How I was taught was mostly rote memorization, but this actually teaches the concepts. I'm still exploring the app, but it looks like it can easily be scaled up or down depending on a learners level and there's a lot of subjects. Great for anyone trying to teach as well. I think the app is a little ugly and not always user friendly. I'd give it 4.5 stars if I could.

Incredible app! Teaches well, and the variety of subjects is astounding! The reason that I'm giving it four stars however, is because all of the videos recorded by the woman took me back to preschool. She talks down to the viewers in a peppy voice, and she started singing about deoxyribonucleic acid? It makes it difficult to watch the videos. Great app otherwise!

Love this app. The lessons are great and exercises actually challenge what you've been taught. I'm probably much older than most people using the app, but I love math (like a game to me). The only issue I have is that some time recently they changed the input and I don't like it. They should also address the issue of nothing happening when you click on a box to input an answer.

What's new

∙ Introducing Experimental Dark Mode! Dark Mode is currently available in select areas of the app. We have future plans to extend it everywhere, but for now, think of it as a moonlit sneak peek. The feature can be turned on and off under Settings.
∙ Bug fixes and performance improvements.
