# Zadarma vs JustCall

The clearest difference is rating: JustCall at 4.4 against Zadarma's 3.2. JustCall also leads on update cadence (weekly vs every 2 months) and ratings volume (1.1K vs 71). Zadarma's advantage is monetization model (free vs freemium) and review sentiment (40% vs 26%). On price, ads, in-app purchases and device support there is nothing between them.

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

JustCall holds the better App Store score, 4.4 against 3.2. That said, the two scores are not equally well evidenced: JustCall has 1.1K ratings behind it against 71, so its average is the more settled of the two. Written reviews complicate that: 40% of Zadarma's written reviews are positive against 26% of JustCall's, so the app with the better star average is not the one people write more warmly about.

Zadarma ships an update every 2 months, JustCall weekly. Both last shipped on November 1, 2026.
