# Cal.com vs Buzz

The clearest difference is rating: Cal.com at 4.8 against Buzz's 4.2. Buzz's advantage is update cadence (every 3 days vs every 3 weeks). On price, review sentiment, ratings volume 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.

Cal.com holds the better App Store score, 4.8 against 4.2. Both are backed by a comparable volume of ratings — 126 and 60 respectively. Written reviews complicate that: 55% of Cal.com's written reviews are positive against 58% of Buzz's, so the app with the better star average is not the one people write more warmly about.

Cal.com ships an update every 3 weeks, Buzz every 3 days. The most recent releases landed on October 12, 2026 and October 11, 2026 respectively.
