Verdict

The call

The clearest difference is rating: Sound Amplifier at 4.6 against Megaphone's 2.8. Sound Amplifier also leads on ads (none vs shown) and update cadence (every 2 weeks vs every 3 months). Megaphone's advantage is review sentiment (52% vs 34%) and device support (4 vs 2). On price, ratings volume, in-app purchases and monetization model there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Sound Amplifier holds the better App Store score, 4.6 against 2.8. Both are backed by a comparable volume of ratings — 593 and 1.3K respectively.
