Verdict

The call

The clearest difference is monetization model: Caliu at free against Evo's paid. Caliu also leads on rating (5.0 vs 4.6) and review sentiment (100% vs 83%). Evo's advantage is ratings volume (24 vs 4) and iOS requirement (16.4 vs 26.0). On price, update cadence, ads and in-app purchases there is nothing between them.
