# Increase Volume vs Volume Master

The clearest difference is review sentiment: Volume Master at 54% against Increase Volume's 17%. Volume Master also leads on monetization model (free with in-app purchases vs subscription). Increase Volume's advantage is update cadence (every 5 days vs every 2 months) and rating (4.4 vs 4.2). On price, ratings volume, ads and in-app purchases there is nothing between them.

Both are free to download. Increase Volume sells 3 in-app purchases, starting at $2.99 per 7 days and Volume Master sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Increase Volume holds the better App Store score, 4.4 against 4.2. Both are backed by a comparable volume of ratings — 429 and 216 respectively. Written reviews complicate that: 17% of Increase Volume's written reviews are positive against 54% of Volume Master's, so the app with the better star average is not the one people write more warmly about.

Increase Volume ships an update every 5 days, Volume Master every 2 months. The most recent releases landed on October 30, 2026 and October 27, 2026 respectively.
