# Deep Whois vs IoT Plug and Play

The clearest difference is review sentiment: Deep Whois at 85% against IoT Plug and Play's 43%. Deep Whois also leads on ratings volume (172 vs 23). IoT Plug and Play's advantage is rating (5.0 vs 4.5) and in-app purchases (none vs 4). On price, device support and iOS requirement there is nothing between them.

IoT Plug and Play holds the better App Store score, 5.0 against 4.5.

Written reviews complicate that: 85% of Deep Whois's written reviews are positive against 43% of IoT Plug and Play's, so the app with the better star average is not the one people write more warmly about.

Deep Whois ships an update every 4 months, IoT Plug and Play every 2 months. The most recent releases landed on October 23, 2026 and October 24, 2026 respectively.
