I can see why other users gave this app a one star. It doesnt allow much customization on the printer sheets, meaning skus may get cut off a bit, wont print out perfectly. Is it usable? Yes. Is it handy? Yes. Can you use it from a phone or your POS? Yes. Is it diamond encrusted? No. Its nothing special, but it's free. You just need the correct type of labels for your printer.
Realm and Reason
Amended review. Problems with printing seem to be fixed and the workflow makes a lot of sense now that I'm getting used to it.
