Navigation Issues

This is an amazing app! It totally works in every way and the glitches that bothered me so much in the past. Just one minor fix so that I could give this app five stars. We need a menu button in our videos and tests. I watch a bunch of videos straight, with tests and stuff, and then If I wan’t to go back to the course, I have to press the back button a million times and go through every single lesson i watched and every test I’ve completed. But the one thing that bothered me the most is that when I encounter one of those articles, I’m just stuck. I enter one, I complete the mini tests, i read the article, and there’s no next button or previous button to go to. I have to double tap and swipe the app and get back on it. But that’s about it. Those two things. And that’s about it.

Oh wait, if you can make the profile a bit more manageable like in the computer, that would be great. Thanks!

So Glitchy it’s Broken

I badly want to give this more stars. When it works, it works really well... I mean it’s really cool to use on my IPad Pro with the pencil. I’ve been attempting to review and re-learn all the basic arithmetic, geometry, algebra, and statistics in preparation for the Praxis Core test. Too often I am unable to complete a task due to malfunctions. This makes it impossible to be consistent with my studies. There is a feedback function within each task which could be very helpful to send messages to the developers on what specific issues to fix. Unfortunately, the feedback function hasn’t been functional since I started using the app. Currently, I have reached an impass within the Arithmetic section. Mastery...not working...individual practice sections...not working. Please fix!

Good website, horrible glitches on app

I’m a big fan of Khan Academy. It’s always been helpful and a good tool to have. I have an iPad 5th generation and this app can never work more than 30 minutes for me before glitching. This morning I log on to do some math and the audio for my lecture cut off. Leaving me with only subtitles and no sound. It also wouldn’t allow me to exit my worksheet after I completed it. This app has been glitching on us iPad users for months now, I ask that these glitches be taken into account for the next update. This is getting ridiculous. I will continue to use the website until then. I hope someone sees this, Thanks.
