# Deep Whois vs TLS Inspector

The clearest difference is in-app purchases: TLS Inspector at none against Deep Whois's 4. TLS Inspector also leads on ads (none vs shown) and rating (4.8 vs 4.5).

TLS Inspector holds the better App Store score, 4.8 against 4.5. Both are backed by a comparable volume of ratings — 172 and 256 respectively. Written reviews complicate that: 85% of Deep Whois's written reviews are positive against 83% of TLS Inspector's, so the app with the better star average is not the one people write more warmly about.
