Recurring themes

Scanning Functionality mixed
Many users praise the app for being fast, reliable, and working well for scanning QR codes. However, a large number of recent reviews report the app failing to scan, not working at all, or displaying a black screen. This directly contradicts the developer's general 'bug fixes and improvements' claim.R1R3R4R7
Ads & Monetization negative
A major concern is the presence of numerous, intrusive, and often deceptive ads. Users report being tricked into clicking ads that lead to scam websites, credit card charges, or unwanted subscriptions. Some reviews mention being charged after a 'free trial' or being asked for credit card information despite the app being advertised as free.R102R145R148R151
Review Authenticity negative
Many users point out that a significant portion of the reviews are clearly fake, irrelevant to a QR code reader, or appear to be AI-generated, leading to distrust in the app's high lifetime rating.R2R8R10R11
Privacy Concerns negative
Users report concerns about the app's privacy practices, including requests to track data, excessive advertising options, and claims of snooping on photos.R160R260

Who it's for

This app might be for users looking for a simple, fast QR code scanner for basic tasks, provided they are vigilant about avoiding deceptive ads and potential subscription traps R1R3R4R16. It is NOT for users who prioritize privacy, dislike intrusive advertising, or need a consistently reliable scanner without unexpected charges R102R148R160R260.

Evidence note: The evidence for privacy concerns is somewhat thin, with only two direct mentions R160R260, but the nature of the claims (snooping on photos, extensive data tracking requests) makes them significant. The high volume of unrelated reviews makes it challenging to gauge the true sentiment for some features.

  13. [R102] 1/5 · US scam app: Has only one ad, which consists of what looks very much like a button marked continue.Managed to use it many times without being fooled into hitting it, but finally did, at a distracted moment. Led directly to a phish website called Cinema something that conned me into giving it my cc info. Charged me $2. I was willing to forget it, but a week later it tried to see if it could get away w

  20. [R160] 1/5 · US snooping privacy: Be careful, this software will snoop on privacy and all photos in the system can be seen, regardless of whether you give it permission or not.
  21. [R260] 2/5 · GB Asks to track data and then copy buttons are broken: A consent cookie form pops up when you open the app asking you to agree to at least 30+ different types of tracking and advertising options. Instant bad feeling about the app. It does work I did some testing but, the copy buttons are broken, so you have to manually copy the data and can’t share it properly. Pretty poor app.

  28. [R245] 1/5 · US Free?: If it’s free, why does it say I have three days free and then it has a weekly payment
  29. [R293] 1/5 · CA Spam application that takes over your phone.: I wanted to test a qrcode with a non native app. It worked fine. This app shows you an ad first and than redirects to your QR code content. That is fine. What is not fine is that once uninstalled your phones native QR code reader still takes you to their ad. This is a spam application, nothing more.
  30. [R326] 1/5 · AU Adssssss: Yes this app can scan QR codes (barely), but the real technological innovation here is the density of advertisements which was straight up just selling another QR code app in their app, right next to a Chinese ad I couldn’t read, which was near the google ads.
