Verdict

The call

The clearest difference is ads: Conversions at none against Conversions's shown. Conversions also leads on update cadence (every 2 weeks vs every 44 months). Conversions's advantage is ratings volume (6 vs 2) and iOS requirement (16.4 vs 18.6). On price, rating, review sentiment and in-app purchases there is nothing between them.
