# Attenuator vs Hearing Amplifier

The clearest difference is rating: Attenuator at 5.0 against Hearing Amplifier's 4.4. Attenuator also leads on monetization model (free with in-app purchases vs subscription) and review sentiment (100% vs 63%). Hearing Amplifier's advantage is update cadence (every 5 weeks vs every 7 months) and ratings volume (928 vs 8). On price, in-app purchases, device support and iOS requirement there is nothing between them.

Both are free to download. Attenuator sells 1 one-off in-app purchase and Hearing Amplifier sells 19 in-app purchases, starting at $0.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Attenuator holds the better App Store score, 5.0 against 4.4. That said, the two scores are not equally well evidenced: Hearing Amplifier has 928 ratings behind it against 8, so its average is the more settled of the two. Written reviews point the same way: 100% of Attenuator's written reviews are positive against 63% of Hearing Amplifier's.

Attenuator ships an update every 7 months, Hearing Amplifier every 5 weeks. The most recent releases landed on October 18, 2026 and October 25, 2026 respectively.
