Verdict
The clearest difference is ads: CORE40 at none against Sisters in Motion's shown. CORE40 also leads on update cadence (every 5 weeks vs every 8 months). Sisters in Motion's advantage is iOS requirement (12.3 vs 16.0). On price, in-app purchases and device support there is nothing between them.
