ReceptionRating · Positive reviews · Number of ratings

Electromag holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: MARVLS has 35 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 45% of Electromag's written reviews are positive against 100% of MARVLS's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Electromag ships an update every 9 months, MARVLS every 8 months. The most recent releases landed on September 26, 2026 and June 11, 2026 respectively.
