Verdict
The clearest difference is in-app purchases: Callsign Search at none against RepeaterBook's 1. Callsign Search also leads on review sentiment (83% vs 67%) and iOS requirement (9.3 vs 15.0). RepeaterBook's advantage is update cadence (every 3 weeks vs every 2 months) and ratings volume (247 vs 39). On price, rating, ads and monetization model 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. RepeaterBook sells 1 in-app purchase, starting at $14.99 per year. Callsign Search asks for nothing beyond the download.
On the App Store both sit at effectively the same score — 4.2 for RepeaterBook against 4.2 for Callsign Search. That said, the two scores are not equally well evidenced: RepeaterBook has 247 ratings behind it against 39, so its average is the more settled of the two. Written reviews are what separate them: 67% of RepeaterBook's written reviews are positive against 83% of Callsign Search's.
RepeaterBook ships an update every 3 weeks, Callsign Search every 2 months. The most recent releases landed on October 29, 2026 and October 23, 2026 respectively.
