# Moen Flo vs KARR Security

The clearest difference is rating: Moen Flo at 4.3 against KARR Security's 2.9. Moen Flo also leads on ratings volume (24K vs 190) and update cadence (fortnightly vs every 2 months). KARR Security's advantage is review sentiment (44% vs 16%). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Moen Flo holds the better App Store score, 4.3 against 2.9. That said, the two scores are not equally well evidenced: Moen Flo has 24K ratings behind it against 190, so its average is the more settled of the two. Written reviews complicate that: 16% of Moen Flo's written reviews are positive against 44% of KARR Security's, so the app with the better star average is not the one people write more warmly about.

Moen Flo ships an update fortnightly, KARR Security every 2 months. Both last shipped on October 15, 2026.
