Cons
Con Can't capture using a camera
Math problem solving apps commonly come with the ability to take a photo of the problem using the device's built-in camera. WolframAlpha lacks that ability.
Con Free version contains ads
The Pro version has no problem. Alternatively, the fdroid version works as well, though it might be annoying to those who want cloud integration because the fdroid version doesn't have cloud integration.
Con No way to set a "home" folder
You have to press the back button a ridiculous amount of times to exit the app and then browse back to your books when you want to read again later.
Con Cannot reverse PDF reflow to return to normal view without exiting the PDF and opening again
Very annoying when you want to view graphics and tables etc.
