Verdict
The clearest difference is rating: Sound Amplifier at 4.6 against The Cipher's 2.8. Sound Amplifier also leads on ratings volume (1.2K vs 6). The Cipher's advantage is in-app purchases (none vs 6) and iOS requirement (12.2 vs 15.0). On price, review sentiment, update cadence and ads there is nothing between them.
