∙ 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.

Arviot ja arvostelut
Fantastic little app
The lessons are brilliant. I’ve been studying mainly math and I can say I love the lessons: they are straightforward and easy to understand. I’m actually getting better!
The app itself is a little buggy—sometimes doing the exercises is a pain because inputting the right data is hard: buttons “bleed off the screen” so I can only see portions of them, or the whole screen moves (like I’m scrolling) when I’m trying to move dots into position on a graph. If things get particularly tough with some exercise though I just swap to the website for that particular bit. Overall, very satisfied. Would recommend.
Good app, lacks features
Great app but it lacks a lot of features that ipad version has. Most wanted feature for me would me the ability to login with my account and continue watching videos where I was left with iPad.
Nothing loads

Kehittäjän vastaus ‚
Hi, there!
Could you please try a few basic troubleshooting steps? Oftentimes, uninstalling and reinstalling the app, disconnecting any idle devices from your network (this ensures it isn’t saturated), and closing any background apps on your device solves this issue.
If you find it persists, please submit a support ticket in our Help Center: http://khan.co/KA-support.
Thank you!
