# ChamberMaster vs Constant Contact

The clearest difference is rating: Constant Contact at 4.8 against ChamberMaster's 3.1. Constant Contact also leads on ratings volume (11K vs 7) and update cadence (fortnightly vs every 6 weeks). ChamberMaster's advantage is review sentiment (60% vs 34%) and iOS requirement (10.0 vs 18.0). On price, ads, in-app purchases and monetization model there is nothing between them.

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

Constant Contact holds the better App Store score, 4.8 against 3.1. That said, the two scores are not equally well evidenced: Constant Contact has 11K ratings behind it against 7, so its average is the more settled of the two. Written reviews complicate that: 60% of ChamberMaster's written reviews are positive against 34% of Constant Contact's, so the app with the better star average is not the one people write more warmly about.

ChamberMaster ships an update every 6 weeks, Constant Contact fortnightly. The most recent releases landed on June 6, 2026 and September 28, 2026 respectively.
