More than I ever wanted in a dictionary. Don't get me wrong, it has tons of really neat features. It's just really, really sloooow. Other than that, it's a 5 star app.

Searching could be better. Even when you try to narrow your search, it still throws an overwhelming visual feast at you.

I use this app like a personalized library of specialized information. I like the way I can download .PDFs from the web or, by using my local wifi, from my desktop computer. A few little things can be improved, but overall, it's one of my favorites. Crashes when opening large files; annoying ads.

I've been a B&W kinda guy most of my life because colors were intimidating and complex. But I'm about to get over it. This app is fun!!

I wish I could use it to write this review.
