Customer Reviews

I would like to rate it 5 stars

For the concept and the arrangement of valuable material.

And I will, once it is rid of the annoying glitches (most of which are connected with the inability of the writing identification algorithm to detect for instance that I’m trying to input O instead of 0, thus leading to incorrect solutions, or the nth root or many other). The app also freezes every now and then. And also it’s impossible to exit review sections (marked with the newspaper icon) other than shutting down and restarting the app. Also 0.5 and 1/2 are the same numbers, but the app accepts usually only one of the options. Etc.
The app also doesn’t allow to send in app feedback, - the send button simply doesn’t react.
The resolution for IPad Pro is too low.

Some content missing!

Khan Academy teaches so many things so well, and it’s free! We’ve been using it in our homeschooling very successfully, but we’ve been forced to rely on the website rather than the app. Sometimes content like Grammar (which is very systematic and fun to learn) is just inexplicably missing from the app. Just isn’t there, not in the subjects listing, nor in the search window. I tried to use it with my ESL students also, but they are also forced to use the website instead of the app due to missing content. So weird!

We love it

We are a family of 4. 2 boys, age 7 and 6, the boys love it. This is the best. Thank you for making it accessible to all. We paid for other math apps in the past but they didn’t have much info and you have to pay for every little upgrade or new things. I understand all apps could be glitchy but that doesn’t mean people should rate it low, It’s on going developing. Thanks again!!!
