It just works well!

It does what it says. This sounds nothing but not that many apps can follow.

1. It searches my scanner in a second, once the scanner connects to WIFI. Much faster than Image Capture.
2. The scanning process is fast and rubust.
3. OCR works well, at least for the normal ducuments that I have tested so far. I do not need to use Acrobat to OCR any more. No waiting time either.
4. Running the app itself is smooth, no lagging or something else.
