Verdict

The call

The clearest difference is review sentiment: CHECK24 at 70% against FNZsecure's 19%. CHECK24 also leads on update cadence (weekly vs every 5 months) and ratings volume (1.9K vs 5). FNZsecure's advantage is monetization model (free vs free with in-app purchases) and rating (5.0 vs 4.8). On price, ads, in-app purchases and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

FNZsecure holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: CHECK24 has 1.9K ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 70% of CHECK24's written reviews are positive against 19% of FNZsecure's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

CHECK24 ships an update weekly, FNZsecure every 5 months. Both last shipped on October 17, 2026.
