# Site Checker vs Security Blink Detector

The clearest difference is price: Security Blink Detector at Free against Site Checker's $1.99. Security Blink Detector also leads on rating (4.5 vs 3.4) and ratings volume (295 vs 12). Site Checker's advantage is in-app purchases (none vs 6) and ads (none vs shown). On review sentiment, device support and iOS requirement there is nothing between them.

Security Blink Detector is free to download; Site Checker costs $1.99 up front. Security Blink Detector sells 6 in-app purchases, starting at $6.99 per 7 days. Site Checker asks for nothing beyond the download.

Security Blink Detector holds the better App Store score, 4.5 against 3.4. That said, the two scores are not equally well evidenced: Security Blink Detector has 295 ratings behind it against 12, so its average is the more settled of the two. Written reviews complicate that: 57% of Site Checker'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.

Site Checker ships an update every 2 months, Security Blink Detector every 8 months. The most recent releases landed on September 18, 2026 and September 19, 2026 respectively.
