I received my first iPhone as a gift on the day it was introduced in the United States. For the record that was on June 29, 2007.
The number of Apps I own (or have owned) was over 3800 at last count.
So, you could say Ive had a lot of experience with Apps.
All that being said, I think this is one of the most well-made, reliable Apps available. I used the free version for a long time (Im amazed its free because yes, its that good) then made the switch to Genius Scan+. And let me tell you; Ive no regrets!
The additional functions set-up very quickly without a single bump and the performance on my iPhone 6s Plus? Phenomenal!
Grizzly, youve earned my respect, my support and my (frequently shared) highest recommendation!
Great Job!
