Verdict
The clearest difference is in-app purchases: B21 Stage Time at none against flo's 3. B21 Stage Time also leads on review sentiment (100% vs 65%). flo's advantage is update cadence (every 5 weeks vs every 4 months) and device support (4 vs 1). On price, ads, monetization model and iOS requirement there is nothing between them.
