It does work for me & doesn't crash on any thing I've accessed...so far! The ads are somewhat annoying, appearing in the middle of the pages bc they pop-up & the timer will 'pause' & not move AT ALL forcing you to either click on the dumb ad if you ARE CLICK STUPID & don't know to just exit the app altogether. This of course will cause A LOT of people to UNINSTALL this for the uncool 'bait & switch' attempt to get the developer, paid for Clicks! I don't & do know how to avoid such tactics - so developer, try another method bc everyone isn't a "Click-Idiot" & still continue to use the app to my benefit, or until I need the storage space, or get bored with the content. Whichever comes 1st!

It crashes every time I try to reed a page
