Verdict
The clearest difference is in-app purchases: Comera at none against Signal's 1. Signal's advantage is ratings volume (1.1M vs 5.3K) and review sentiment (68% vs 53%). On price, rating, update cadence and ads 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. Signal sells 1 in-app purchase, starting at $1.99 per month. Comera asks for nothing beyond the download.
On the App Store both sit at effectively the same score — 4.7 for Signal against 4.6 for Comera. That said, the two scores are not equally well evidenced: Signal has 1.1M ratings behind it against 5.3K, so its average is the more settled of the two. Written reviews are what separate them: 68% of Signal's written reviews are positive against 53% of Comera's.
Signal ships an update weekly, Comera every 8 days. The most recent releases landed on October 29, 2026 and October 26, 2026 respectively.
