Best QR Scanner App

As someone who has pretty much downloaded and tested every QR Scanner on the App Store, I can confirm that this is hands down the best QR Scanner App.

(+) It has a nice interface design
(+) Extremely fast scan results
(+) Options for creating QR Codes
(+) A good amount of settings
(+) Best of all, No Annoying Ads or Subscription

All the other apps are a mix bag and this is the only free one that gets it all done right.

Micro QR

Only free app I’ve found that scans Micro QR, and does it very fast.
