Verdict
The clearest difference is rating: Sound Amplifier at 4.6 against DS's 1.0. Sound Amplifier also leads on review sentiment (34% vs 0%) and update cadence (every 2 weeks vs every 3 months). DS's advantage is in-app purchases (none vs 6) and iOS requirement (10.0 vs 15.0). On price, ads and device support there is nothing between them.
