Verdict
The clearest difference is update cadence: Zero Camera at every 2 weeks against Secret Key Lock Album's every 3 months. Secret Key Lock Album's advantage is ratings volume (7.7K vs 4) and iOS requirement (14.0 vs 17.0). On price, rating, review sentiment and ads there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Secret Key Lock Album sells 2 one-off in-app purchases and Zero Camera sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
Zero Camera holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Secret Key Lock Album has 7.7K ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 82% of Secret Key Lock Album's written reviews are positive against 77% of Zero Camera's, so the app with the better star average is not the one people write more warmly about.
Secret Key Lock Album ships an update every 3 months, Zero Camera every 2 weeks. The most recent releases landed on November 1, 2026 and November 2, 2026 respectively.
