Great program and I would rate it higher but there is no way to save my books on a SIM card. I have a Nokia 820 and have limited space.

Has a hard time remembering where I am in a book. Very random.

Very good app. Love it

Love the service growing to hate the app for one killer defect. It doesn't store its place if it is interrupted. I have had several hours of reading disappear after getting a phone call. Once this is fixed then whispersync would be really nice.

Great app. Does everything with precision and speed. Looks nice too.

Doesn't work on my HTC Trophy with Win 7.5.

Glitchy, but better than nothing.

Love it! Use it everyday, service is great, works perfectly on the Lumia 822.

About time! I love the fact that I was able to download a book over the 4g connection instead of being forced to use WiFi. Update & loss of a star: since moving from wp7.5 to wp8, the app occasionally loses my place in the book. It is displayed on the section tile correctly, but will start from the beginning of the section. This is tough to deal with when driving.

Love it....
