# Chess Cloud PBX vs Zrada

The clearest difference is rating: Zrada at 5.0 against Chess Cloud PBX's 4.0. Zrada also leads on update cadence (every 9 days vs every 3 months) and ratings volume (21 vs 1). Chess Cloud PBX's advantage is in-app purchases (none vs 8) and review sentiment (100% vs 88%). On price and ads there is nothing between them.

Both are free to download. Zrada sells 8 in-app purchases, starting at $0.99 per month. Chess Cloud PBX asks for nothing beyond the download.

Zrada holds the better App Store score, 5.0 against 4.0. That said, the two scores are not equally well evidenced: Zrada has 21 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 100% of Chess Cloud PBX's written reviews are positive against 88% of Zrada's, so the app with the better star average is not the one people write more warmly about.

Chess Cloud PBX ships an update every 3 months, Zrada every 9 days. The most recent releases landed on October 3, 2026 and October 2, 2026 respectively.
