# Volume Booster vs Sound Amplifier

The clearest difference is rating: Sound Amplifier at 4.6 against Volume Booster's 3.6. Sound Amplifier also leads on ads (none vs shown). Volume Booster's advantage is review sentiment (57% vs 34%). On price, ratings volume, update cadence and in-app purchases there is nothing between them.

Both are free to download. Volume Booster sells 5 in-app purchases, starting at $2.99 per 7 days and Sound Amplifier sells 4 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.

Sound Amplifier holds the better App Store score, 4.6 against 3.6. Both are backed by a comparable volume of ratings — 681 and 1.2K respectively. Written reviews complicate that: 57% of Volume Booster's written reviews are positive against 34% of Sound Amplifier's, so the app with the better star average is not the one people write more warmly about.

Volume Booster ships an update every 3 weeks, Sound Amplifier every 2 weeks. The most recent releases landed on September 19, 2026 and September 23, 2026 respectively.
