# Hidden Camera vs QRReader

The clearest difference is review sentiment: QRReader at 100% against Hidden Camera's 14%. QRReader also leads on update cadence (fortnightly vs every 3 months). Hidden Camera's advantage is rating (4.5 vs 3.6) and ratings volume (369 vs 5). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Hidden Camera sells 2 in-app purchases, starting at $7.99 per 7 days and QRReader sells 4 in-app purchases, starting at $2.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Hidden Camera holds the better App Store score, 4.5 against 3.6. That said, the two scores are not equally well evidenced: Hidden Camera has 369 ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 14% of Hidden Camera's written reviews are positive against 100% of QRReader's, so the app with the better star average is not the one people write more warmly about.

Hidden Camera ships an update every 3 months, QRReader fortnightly. The most recent releases landed on October 23, 2026 and October 24, 2026 respectively.
