Verdict
The clearest difference is ads: REPC at none against CallSign Check's shown. REPC also leads on monetization model (free vs ad-supported). CallSign Check's advantage is update cadence (every 2 weeks vs monthly). On price, review sentiment, in-app purchases and device support there is nothing between them.
