Finally, an app that shows the GS character!
After searching for quite a while, I finally found it. An iOS app I can use to help debug GS1 barcodes! Not only does it show that all-important GS character, but it even parses the various GS1 segments for me so I don't have to do it in my head. Thank you for putting in the work on this, Toni! Definitely worth my $2 👍
