1★Thought this app was great at the start, then realized it was nothing more than a redirect app to numerous other apps, most of which were some type of security suite, VPNs, Virus Scanners, etc. Lots of other options which all look the same or similar. Walk Away! Ratings don't tell the whole story. I would have recommended the app just after I got it. But somewhere down the trail, the developers must have grown some greed and sold out to "redirects" who pay them a commission for the redirects.

5★I just downloaded this app. Initially I had a negative reaction when I scanned a QR code. it prominently showed an ad in the middle and choosing Continue at the bottom would have taken me to the ad. Solutions: First, simply look at the top of your screen and choose the displayed URL you just scanned. This takes you to where you want to be. Second, in Settings, select "automatically open the scanned URL." Next time, it will go straight to the scanned URL. Great App. Scans with lightening speed.

1★When scanning a QR code, an ad will come up in middle of screen. I didn't realize this was an ad so I clicked on Open and put in my credit card to pay for parking. Well, turns out it was not the parking site I was on. it was a fraudulent company that charged my credit card on 2 separate occasions days apart and my bank notified me and I had to cancel credit card. Stop letting fraudulent companies advertise on your app!!

1★Similar complaint as other users have said. When I scanned a QR, it brought up two links. One link with a big blue button that was actually an ad. The other link which was the one I wanted, was much more inconspicuous. I was in a rush trying to pay for parking. I accidentally opened the ad link thinking it was to pay for parking. I foolishly filled out the form and entered my credit card info. Now, my bank account has been hacked because the link is a scam site. 1 star for hosting a scam.

1★Like many others have stated, the App plaves it's ads in a way that causes you to mistakenly click them, which lead to me having to replace my debit card. And for the likely reply I'll get to tgis no it's not because of the QR Code I scanned and yes your app is free and having ads isn't a bad thing but put them at the very top of the app not dead center with a huge blue "Open" button. Seriously, that's uncalled for. Also, before it's said no, I did not confuse this app for another one.
