# Underwatch vs Flyboys

The clearest difference is in-app purchases: Underwatch at none against Flyboys's 1. Underwatch also leads on review sentiment (79% vs 45%). Flyboys's advantage is rating (4.3 vs 4.0) and update cadence (weekly vs every 3 weeks). On price, ratings volume, ads and device support there is nothing between them.

Written reviews complicate that: 79% of Underwatch's written reviews are positive against 45% of Flyboys's, so the app with the better star average is not the one people write more warmly about.
