# SigTrax vs MQTT Terminal

The clearest difference is rating: SigTrax at 3.6 against MQTT Terminal's 3.0. SigTrax also leads on chart position (#190 vs unranked) and ratings volume (8 vs 2). MQTT Terminal's advantage is review sentiment (100% vs 60%) and update cadence (monthly vs every 3 months). On ads, in-app purchases, monetization model and device support there is nothing between them.

SigTrax costs $2.99 and MQTT Terminal $0.99 up front. SigTrax sells 2 one-off in-app purchases and MQTT Terminal sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

SigTrax holds the better App Store score, 3.6 against 3.0. Both are backed by a comparable volume of ratings — 8 and 2 respectively. Written reviews complicate that: 60% of SigTrax's written reviews are positive against 100% of MQTT Terminal's, so the app with the better star average is not the one people write more warmly about.

SigTrax ships an update every 3 months, MQTT Terminal monthly. The most recent releases landed on October 26, 2026 and October 24, 2026 respectively.
