ReceptionRating · Positive reviews · Number of ratings

WATERROWER Connect holds the better App Store score, 4.3 against 3.0. That said, the two scores are not equally well evidenced: WATERROWER Connect has 972 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 23% of WATERROWER Connect's written reviews are positive against 60% of ImersU's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Both ship on a similar rhythm, roughly every 2 weeks. The most recent releases landed on November 10, 2026 and November 3, 2026 respectively.
