Verdict
The clearest difference is in-app purchases: Reflex Lab at none against Flow Free's 18. Reflex Lab also leads on ads (none vs shown) and update cadence (monthly vs every 7 months). Flow Free's advantage is iOS requirement (13.0 vs 15.1). On price and device support there is nothing between them.
