# EFQRCode vs Proximity Lock

The clearest difference is rating: Proximity Lock at 5.0 against EFQRCode's 4.3. Proximity Lock also leads on update cadence (every 9 days vs every 2 months). EFQRCode's advantage is in-app purchases (none vs 1) and review sentiment (33% vs 0%). On price, ads, monetization model and device support there is nothing between them.

Both are free to download. Proximity Lock sells 1 one-off in-app purchase. EFQRCode asks for nothing beyond the download.

Proximity Lock holds the better App Store score, 5.0 against 4.3. That said, the two scores are not equally well evidenced: EFQRCode has 11 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 33% of EFQRCode's written reviews are positive against 0% of Proximity Lock's, so the app with the better star average is not the one people write more warmly about.

EFQRCode ships an update every 2 months, Proximity Lock every 9 days. The most recent releases landed on June 1, 2026 and September 3, 2026 respectively.
