Verdict

The call

The clearest difference is in-app purchases: Concept at none against Signal's 1. Concept also leads on review sentiment (100% vs 68%) and rating (5.0 vs 4.7). Signal's advantage is ratings volume (1.1M vs 19) and chart position (#11 vs unranked). On price, ads, monetization model and device support there is nothing between them.
