Verdict
The clearest difference is rating: OpenSpam at 3.9 against Magnifier · Baro's 2.0. OpenSpam also leads on ratings volume (10 vs 1). Magnifier · Baro's advantage is monetization model (free vs paid) and update cadence (every 3 days vs every 3 weeks). On price, ads, in-app purchases and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
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.
OpenSpam ships an update every 3 weeks, Magnifier · Baro every 3 days. Both last shipped on October 25, 2026.
