# Device System Services vs IoT Plug and Play

The clearest difference is rating: IoT Plug and Play at 5.0 against Device System Services's 4.5. IoT Plug and Play also leads on in-app purchases (none vs 1) and ads (none vs shown). Device System Services's advantage is ratings volume (394 vs 22) and review sentiment (52% vs 43%). On price and device support there is nothing between them.

Both are free to download. Device System Services sells 1 one-off in-app purchase. IoT Plug and Play asks for nothing beyond the download.

IoT Plug and Play holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: Device System Services has 394 ratings behind it against 22, so its average is the more settled of the two. Written reviews complicate that: 52% of Device System Services'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.

Device System Services ships an update every 4 months, IoT Plug and Play every 2 months. Both last shipped on October 17, 2026.
