# myStrom Mobile vs S

The clearest difference is rating: myStrom Mobile at 5.0 against S's 4.3. myStrom Mobile also leads on device support (4 vs 2). S's advantage is in-app purchases (none vs 10) and review sentiment (66% vs 51%). On price, update cadence, ads and iOS requirement there is nothing between them.

Both are free to download. myStrom Mobile sells 10 in-app purchases, starting at $2.99 per year. S asks for nothing beyond the download.

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.

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