5 stars: No nonsense qr scanner app with minimal ads. Many other apps will show you ads between scanning, making successive scanning very slow. This app can also scan qr code from photos in an intuitive way. They have a history function if you want to see what you have scanned, and can make a history.CSV file if you need it for some reason. Good app, recommended.
5 stars: Literally perfect for all my QR code reading needs. It directly gives me the encoded string values while also providing useful post-processing features like opening in a browser and copying to clipboard. Not to mention the thing works on bar codes, and doesn't have intrusive ads.
4 stars: This is a well made free app with relatively few advertisements. I don't know how they make their money though, so they could be stealing your data, just watch out for that possibility.
4 stars: Generally good for most kind qr reading . Rarely noticed some kind doesn't support.
2 stars: Very basic. Poor looking UI.
2 stars: There is no instructions on how to use the scanner, the instructions that are there don't tell you what the boxes that show up after you scan codes do when selected or which box to use
