I've just released a free app for exchanging contact info via QR codes. I'd appreciate if any of you could check it out and give me feedback. In particular I'm looking for bugs, suggestions for improvement, and honest opinions as to whether this app is useful/marketable. Thanks in advance! I'm happy to reciprocate, by testing/reviewing an app of yours, and also if you provide me useful criticism I can give you an ad free copy of my final version. Just contact me, and let me know what you'd like! The app is available at: https://play.google.com/store/apps/details?id=com.pipsqueaksoftware.secs And please send your feedback to: firstname.lastname@example.org (or just post below) I appreciate your help.
