Verdict
The clearest difference is price: MQTTAnalyzer at Free against Theengs BLE's $3.99. MQTTAnalyzer also leads on update cadence (every 5 days vs every 5 months) and review sentiment (78% vs 50%). Theengs BLE's advantage is rating (5.0 vs 4.5) and iOS requirement (16.0 vs 18.0). On ads, in-app purchases and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
MQTTAnalyzer is free to download; Theengs BLE costs $3.99 up front. Neither carries in-app purchases, so what you see is what you pay.
Theengs BLE holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: MQTTAnalyzer has 22 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 78% of MQTTAnalyzer's written reviews are positive against 50% of Theengs BLE's, so the app with the better star average is not the one people write more warmly about.
MQTTAnalyzer ships an update every 5 days, Theengs BLE every 5 months. The most recent releases landed on September 21, 2026 and September 9, 2026 respectively.
