# DNS Security vs SSL Certificate Checker

The clearest difference is in-app purchases: SSL Certificate Checker at none against DNS Security's 1. SSL Certificate Checker also leads on review sentiment (100% vs 67%) and rating (5.0 vs 4.8). DNS Security's advantage is update cadence (every 2 days vs monthly) and ratings volume (72 vs 2). On price, ads and device support there is nothing between them.

Both are free to download. DNS Security sells 1 one-off in-app purchase. SSL Certificate Checker asks for nothing beyond the download.

SSL Certificate Checker holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: DNS Security has 72 ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 67% of DNS Security's written reviews are positive against 100% of SSL Certificate Checker's.

DNS Security ships an update every 2 days, SSL Certificate Checker monthly. The most recent releases landed on November 3, 2026 and October 31, 2026 respectively.
