QR Serve
Read full descriptionHide full description
QR Serve is a QR code wallet for the codes you show other people: your website, your social profiles, your portfolio and the places you send people to, each ready to show full screen when someone asks. A QR CODE WALLET FOR THE CODES YOU SHARE Think of it as a card case for everything you point people to. Every link, profile and place becomes a QR code of its own, and they all live together in one wallet app on your iPhone. When someone asks where to find you, the right code is already there, big and easy to scan. LINK TO QR CODE: YOUR WEBSITE AND PROFILES A link from your browser or another app becomes a QR code you can keep: your website, your online shop, a professional or social profile, a booking page, a fundraiser. At a meetup or a market stall, people scan your profile and open it on their own phone instead of copying a handle or a long address. A PORTFOLIO QR CODE FOR INTERVIEWS AND REVIEWS How do I create a QR code for my portfolio? A link to your work becomes a portfolio QR code. Designers, photographers, job seekers and freelancers keep one ready for interviews, reviews and fairs, so the other person sees the work while you are still talking. A LOCATION QR CODE FOR YOUR PLACE A location QR code lets someone open the place on their own phone. Keep your shop, studio, office, venue or meeting point as a code, and whoever scans it gets the spot itself instead of a misspelled street name. SAVE A QR CODE ON YOUR iPHONE Is there a way to save a QR code? Yes. QR Serve can save a ready QR code you scan with the camera, so you can keep it with your own codes and show it again later. You can also save a code as an image, with its link's title and domain underneath, ready to add to a resume, document, or printed material. SHOW A QR CODE ON YOUR iPHONE, EVEN OFFLINE Your codes are stored on your phone and open without an internet connection, so you can show a QR code in a basement venue, on a plane or abroad with no data. Make your codes once, keep them in one place, and show the right one when it counts.

Verdict
The clearest difference is iOS requirement: Passcode at 10.0 against QR Serve's 17.6. On price, ads, in-app purchases and device support there is nothing between them.
