Verdict
The clearest difference is in-app purchases: FRMSc Survey at none against Crew Roster's 2. FRMSc Survey also leads on device support (3 vs 1) and iOS requirement (15.1 vs 17.0). Crew Roster's advantage is update cadence (every 4 days vs fortnightly). On price and ads there is nothing between them.
