# Rdio Scanner vs Hearing Amplifier

The clearest difference is rating: Hearing Amplifier at 4.4 against Rdio Scanner's 3.3. Hearing Amplifier also leads on review sentiment (63% vs 44%) and ratings volume (929 vs 84). Rdio Scanner's advantage is ads (none vs shown). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. Rdio Scanner sells 1 in-app purchase, starting at $39.99 per year 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.
