Bowtique It review for Retail Barcode Labels

I like using this app but I hate the limitation of the label sizes. Especially, when I got a phomemo label printer and can't find the right size label to print. I have a 1.5 x 1 labels on a roll and there are no option for this size or no option for a 2.25x1 option either. I expected when click on other options there would be an option for custom but nope.
