Customer Reviews

Has a lot of good features, but....

This app still needs a lot of work. I wasted $10 in my opinion. Text to speech does not flow smoothly. It pauses at the end of each line, even in the middle of a sentence, which makes it hard to follow.
The scanner does not have automatic edge detection, like most other scanner apps do. The horizontal scroll is "loose". Sloppy. Nothing like turning a page, which most people would expect from horizontal scrolling.

Does not actually "sync" to DropBox, etc. You have to download each file to a download folder to edit. Would be much better if you could edit the file "in place" and the edited file would be automatically sync'd back to DropBox.

I had high hopes for this app, because the concept of it would replace 3 separate apps that I have. Unfortunately, it falls short, so I am back to using the other apps.

Would change this rating if Developer fixes the above...


Took me some time to accustom myself to how everything works, but once I did, I was hooked! Brilliant, easy to use (once you take time to play with all the options it offers), and saves me time looking for downloaded material, favorite pages, or required passages for quick and easy studying.. Please please please add more cool features!! This already rocks but I have to download several apps to get everything I need for school, like recorders and text to speech apps..just incorporate that here so I can delete the rest!!

Great app. Very useful indeed.

I really appreciate the functionality of this PDF application. I have been using it as my reference during my preaching, and piano playing. It holds all the materials that i need from books to read to maps that i use during my speaking. Anything that is in PDF format can be loaded here and it even has the ability to convert my existing documents created in MS word.
