Scans OK, but takes effort.

The app is good. It scans codes OK. I think the problem that other people are having are due to the Macbook camera not focusing at macro distance. I had to move back and forth a few times to get a code on a screen scanned.
The dev’s should put a little tip somewhere in the app suggesting the correct way to make the scan on the MacBook.
