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!

Ever since Covid, I've loved Khan Academy. Its free math courses allowed me to get ahead, and their customer service is in my experience, unmatched. I once had an issue (that was completely my fault) that I needed help from the Khan Academy team to fix. When I sent in a request, less than two minutes later, they had fixed it and notified me. This is truly my favorite app for learning.
