Verdict
The clearest difference is in-app purchases: SRF/YSS at none against FlowBuilder's 7. SRF/YSS also leads on ratings volume (400 vs 9) and iOS requirement (14.0 vs 17.0). FlowBuilder's advantage is update cadence (every 2 weeks vs every 2 months) and review sentiment (100% vs 83%). On price, rating and ads there is nothing between them.
