Verdict
The clearest difference is price: Flow at Free against WatchWords's $0.99. Flow also leads on update cadence (every 4 weeks vs every 13 months) and device support (5 vs 3). WatchWords's advantage is in-app purchases (none vs 3) and iOS requirement (15.0 vs 26.0). On ads there is nothing between them.
