Amazing magazine, really. The content is great. The previous version of the app was bad. People were complaining about the app crashing all the time. The developers listened to them, but it would have been better if they hadnt.
To summarise: the app needed baby-sitting all the time while downloading issues, it could not download 2 issues at the same time, you had to manually tap on each once one was finished. Then there were the issues about the app crashing all the time while trying to read the magazine (which, by the way, is AMAZINGLY GOOD and deserves 7 stars).
They decided to overhaul the whole app. It just made things a lot worse, not least because all already downloaded issues in high resolution need to be downloaded again. And you cant download them in high-def!!!
Hours spent baby-sitting the app down the drain because of some idiotic decision.
A shame, because, as already stated, the magazine deserves much more than this piece of crap.
If I were Mr Scientific American, I would immediately fire the whole app-developing team (maybe not the actual coders, certainly the manager and the alpha- and beta-testers) and hire someone competent.
Sorry, guys, but this app really sucks
