ReceptionRating · Positive reviews · Number of ratings

myStrom Mobile holds the better App Store score, 5.0 against 4.3. That said, the two scores are not equally well evidenced: S has 15 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 51% of myStrom Mobile's written reviews are positive against 66% of S's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

myStrom Mobile ships an update every 2 weeks, S monthly. The most recent releases landed on November 6, 2026 and November 7, 2026 respectively.
