Excellent videos, buggy and slow app

I love the videos and I am so grateful for them. I wouldn’t have a clue about limits in calculus if it weren’t for these videos because my professor can’t teach to save her life and the book we were assigned is awful, it doesn’t really explain anything. But these videos do. They show how to do problems instead of throwing definitions and formulas in your face. They really teach and I’m so thankful to the people who worked to put them together. The app, I’ve had a lot of issues with, though. It stops responding when trying to complete quizzes, certain things just won’t download, even with a 100% strength WiFi signal, ample space, and days of time. I also can’t view any progress details on my profile, though I can see a general summary. I think the app really needs work. The problem may be the servers, in part because it slows down when using the app, but I’ve had that same speed issue on my laptop with the website. I don’t have speed issues with other websites, so it’s not my connection. Maybe add an option to donate in the app? I’d be happy to support fixing things after how useful the videos have been. (You deserve the money a heck of a lot more than my calculus professor, as far as I’m concerned!)

Looking for a Developer Response

Pretty good app. I am giving it five stars, even though a recent update put everything in deeper layers. I used to be able to see every video, article, and practice exercise for a course, plus its mission if it has one, on the same screen. Now I have to dig deeper. Please return an expanded view to us! Also, we no longer see our consecutive days streak.

The iPad app is missing a few things found in the web version, in addition to the consecutive days streak, but it is quite adequate for the learning experience.

The most maddening thing is that when you roll out a new version with a major change like this, you still say “Bug fixes and performance enhancements.” Please give this review a Developer Response and let us know that you will {in the future/in future} be detailed with your updates when something major like the whole interface changes. Also, please let us know why the consecutive days counter (more motivating to me than energy points and about as motivating as the badges) was removed and if there’s a chance we can get it back. Thanks!
