Verdict

The call

The clearest difference is ads: A Chain Reaction at none against Cell to Singularity's shown. A Chain Reaction also leads on iOS requirement (7.0 vs 15.0). Cell to Singularity's advantage is update cadence (every 2 weeks vs every 5 months) and ratings volume (23K vs 50). On price, in-app purchases, monetization model and device support there is nothing between them.
