What users are saying

1. The latest update defaults to auto-open links, and the way to revert to the safer option is by clicking the "crop" icon on the main screen which doesn't give any indication that this is what it does.

2. it took me a few minutes to figure out the code needed to be straight in the camera frameWow! What a smooth and effective GUI! I’m impressed! Just as I was giving up thinking that QR scanners cannot be improved further any longer, I came across this gem.

3. I use this at work all the time to scan barcodes and this is the most responsive and clutter-free barcode reader on the play store.

4. (Galaxy Tab S2)I used this as my QR reader of choice because it didn't have the glaring security hole of following links in codes automatically.

5. I would recommend an option to choose when it scans as it did scan the barcode 1st (test 2) which I didn't need.

6. Can scan multiple, tiny QR codes at the same time, displaying all results at once.

7. I have only scanned qr that are product codes so if the qr is a url it might pull that up automatically? as it is I copied the result using the copy button and pasted it into the browser.

8. For a product or a manufacturer it will offer links to search Amazon, eBay and other sites.

9. Thank you for your service! 🖖 *09/15/20* Autofocus speed and low light performance have increased pretty significantly after the last update! Thank you again for your continued service.

10. Barely installed when it started & accidently caught site of the QR code I was installing it to read & it promptly brought up the correct link.

11. However, I am adding 2 stats back on since the safer behavior is still available.Great variety of bar and 2D codes.
