ReceptionRating · Positive reviews · Number of ratings

Surrey SP holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Polar Flow has 50K ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 50% of Polar Flow's written reviews are positive against 0% of Surrey SP'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 monthly. The most recent releases landed on November 9, 2026 and November 4, 2026 respectively.
