Verdict
The clearest difference is price: FlatPromo at Free against DJ Sound FX's $0.99. FlatPromo also leads on update cadence (every 3 weeks vs every 46 months). DJ Sound FX's advantage is chart position (#196 vs unranked) and iOS requirement (13.4 vs 15.6). On ads, in-app purchases and device support there is nothing between them.
