Verdict

The call

The clearest difference is ads: Shadow at none against Cell to Singularity's shown. Shadow also leads on review sentiment (100% vs 82%) and iOS requirement (12.0 vs 15.0). Cell to Singularity's advantage is ratings volume (23K vs 69) and update cadence (fortnightly vs every 6 weeks). On price, rating, in-app purchases and monetization model there is nothing between them.
