Verdict
The clearest difference is ads: Flight Deck FMS at none against RevHeadz Engine Sounds's shown. Flight Deck FMS also leads on review sentiment (100% vs 69%) and update cadence (every 5 days vs every 3 months). RevHeadz Engine Sounds's advantage is ratings volume (1.4K vs 5) and iOS requirement (12.0 vs 17.5). On price, rating, in-app purchases and monetization model there is nothing between them.
