Verdict

The call

The clearest difference is ads: Sound Amplifier | Volume Boost at none against Magniscope's shown. Sound Amplifier | Volume Boost also leads on review sentiment (84% vs 58%) and rating (4.5 vs 4.2). Magniscope's advantage is update cadence (every 5 weeks vs every 4 months) and iOS requirement (12.0 vs 14.0). On price, in-app purchases, monetization model and device support there is nothing between them.
