Verdict
The clearest difference is review sentiment: CallBell at 78% against Odmaster's 29%. Odmaster's advantage is ads (none vs shown) and update cadence (every 3 weeks vs every 21 months). On price, in-app purchases, device support and iOS requirement there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
Odmaster holds the better App Store score, 3.8 against 3.5. That said, the two scores are not equally well evidenced: Odmaster has 1.1K ratings behind it against 30, so its average is the more settled of the two. Written reviews complicate that: 29% of Odmaster's written reviews are positive against 78% of CallBell's, so the app with the better star average is not the one people write more warmly about.
Odmaster ships an update every 3 weeks, CallBell every 21 months. The most recent releases landed on October 15, 2026 and October 5, 2026 respectively.
