# MQTTool vs MQTT Loupe

The clearest difference is rating: MQTT Loupe at 5.0 against MQTTool's 4.3. MQTTool's advantage is review sentiment (77% vs 50%) and ratings volume (26 vs 1). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

MQTT Loupe holds the better App Store score, 5.0 against 4.3. That said, the two scores are not equally well evidenced: MQTTool has 26 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 77% of MQTTool's written reviews are positive against 50% of MQTT Loupe's, so the app with the better star average is not the one people write more warmly about.

MQTTool ships an update every 4 weeks, MQTT Loupe every 3 weeks. The most recent releases landed on November 2, 2026 and November 3, 2026 respectively.
