# MQTTAnalyzer vs TrueNTP

The clearest difference is rating: TrueNTP at 5.0 against MQTTAnalyzer's 4.5. TrueNTP also leads on review sentiment (100% vs 81%) and iOS requirement (15.0 vs 18.0). MQTTAnalyzer's advantage is in-app purchases (none vs 1) and ads (none vs shown). On price and device support there is nothing between them.

Both are free to download. TrueNTP sells 1 one-off in-app purchase. MQTTAnalyzer asks for nothing beyond the download.

TrueNTP holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: MQTTAnalyzer has 23 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 81% of MQTTAnalyzer's written reviews are positive against 100% of TrueNTP's.
