Verdict
The clearest difference is in-app purchases: Periodic at none against Chemical Equation's 1. Periodic also leads on update cadence (every 5 weeks vs every 5 months). Chemical Equation's advantage is iOS requirement (10.0 vs 15.1). On price, ads and device support there is nothing between them.
