ReceptionRating · Positive reviews · Number of ratings

OpenSpam holds the better App Store score, 3.9 against 2.0. That said, the two scores are not equally well evidenced: OpenSpam has 10 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 25% of OpenSpam's written reviews are positive against 50% of Magnifier · Baro's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

OpenSpam ships an update every 3 weeks, Magnifier · Baro every 3 days. Both last shipped on October 25, 2026.
