# CmsApp vs Callbook

The clearest difference is update cadence: Callbook at every 2 days against CmsApp's every 3 months. Callbook also leads on rating (5.0 vs 4.7). CmsApp's advantage is ratings volume (23 vs 1) and iOS requirement (12.2 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.

Callbook holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: CmsApp has 23 ratings behind it against 1, so its average is the more settled of the two.

CmsApp ships an update every 3 months, Callbook every 2 days. The most recent releases landed on October 9, 2026 and October 1, 2026 respectively.
