ReceptionRating · Positive reviews · Number of ratings

iPerf3 Client & Server holds the better App Store score, 4.9 against 4.5. That said, the two scores are not equally well evidenced: Liquid Apollo has 680 ratings behind it against 12, so its average is the more settled of the two. Written reviews complicate that: 68% of Liquid Apollo's written reviews are positive against 57% of iPerf3 Client & Server's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Liquid Apollo ships an update every 8 days, iPerf3 Client & Server every 4 days. Both last shipped on November 12, 2026.
