QR Droid

★★★★★ Has ads but is free ... And it works without trying to scam the user with intrusive ad placement.

★★★★★ Fabulous app! Make or decode QRs. Scan many types of codes, too! Barcodes, etc. The Wi-Fi plugin is great - make & print Wi-Fi access QRs. Handy! Used this for 3+yrs now and never a single problem (Andrd v8-12!).

★★★★★ Quick and easy application for scanning QR codes. As specially if your smartphone doesn't have an onboard QR code scanner app installed.

★★☆☆☆ Allows advertisers to mislead you into downloading apps you don't want. How? Use QR to scan a code for another app you want, and a big green box with the word "DOWNLOAD" appears. But it is actually a link for the advertiser's app that you don't want. Below that in practically invisible letters is a link to a website, with no instructions. That's the link that has the app you want. Most consumers are going to get roped into downloading AND REGISTERING for the app they don't want, then AFTER giving away their private information, try to use the unwanted app and find it is not what they wanted. Too late - the advertiser has the consumer's info and has tricked them into downloading its app. The advertiser profits, QR Droid profits, and the consumer loses. And the consumer usually thinks that it's their own fault - that they could have clicked the correct link if only they paid more attention. IMHO: BS. The app is designed to fool the average consumer and then avoid accountability.
