OH YEAH I forgot to mention this in the last comment but KA is really fun but idk if you can do everything from the app? But uh I last tried the app when KA was pretty new and I was using the Windows Phone app so... lol. Like it would only let you watch the videos but you couldn't read articles or do the practices or challenges. But yeah as long as you like learning things or doing math class stuff it's fun XD Filling up the squares is so satisfying lmfao.

But if the app is shit, the website works even on mobile, though probably better on a tablet.
