ReceptionRating · Positive reviews · Number of ratings

SKC SmartWave holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: ERG for iOS has 65 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 0% of SKC SmartWave's written reviews are positive against 100% of ERG for iOS's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

SKC SmartWave ships an update every 18 months, ERG for iOS every 4 months. The most recent releases landed on September 26, 2026 and October 25, 2026 respectively.
