# Kaktus vs Datovka.cz

The clearest difference is rating: Datovka.cz at 4.5 against Kaktus's 1.0. Datovka.cz also leads on ratings volume (44 vs 1) and monetization model (free vs ad-supported). On price, review sentiment, update cadence and ads there is nothing between them.

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

Datovka.cz holds the better App Store score, 4.5 against 1.0. That said, the two scores are not equally well evidenced: Datovka.cz has 44 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 25% of Kaktus's written reviews are positive against 17% of Datovka.cz's, so the app with the better star average is not the one people write more warmly about.

Kaktus ships an update every 2 months, Datovka.cz every 6 weeks. Both last shipped on October 21, 2026.
