# ScanMaster vs Security Blink Detector

The clearest difference is rating: ScanMaster at 5.0 against Security Blink Detector's 4.5. ScanMaster also leads on ads (none vs shown) and update cadence (every 5 weeks vs every 8 months). Security Blink Detector's advantage is review sentiment (50% vs 25%) and ratings volume (295 vs 4). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. ScanMaster sells 5 in-app purchases, starting at $3.99 per 7 days and Security Blink Detector sells 6 in-app purchases, starting at $6.99 per 7 days. Whichever you choose, the download price is not the number that matters.

ScanMaster holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: Security Blink Detector has 295 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 25% of ScanMaster's written reviews are positive against 50% of Security Blink Detector's, so the app with the better star average is not the one people write more warmly about.

ScanMaster ships an update every 5 weeks, Security Blink Detector every 8 months. The most recent releases landed on September 3, 2026 and September 19, 2026 respectively.
