# Speaker Volume Booster vs Driver4VR

The clearest difference is review sentiment: Driver4VR at 47% against Speaker Volume Booster's 0%. Driver4VR also leads on ads (none vs shown). Speaker Volume Booster's advantage is rating (4.5 vs 3.5) and iOS requirement (12.4 vs 15.0). On price, ratings volume, update cadence and in-app purchases there is nothing between them.

Both are free to download. Speaker Volume Booster sells 1 in-app purchase, starting at $9.99 per month and Driver4VR sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Written reviews complicate that: 0% of Speaker Volume Booster's written reviews are positive against 47% of Driver4VR's, so the app with the better star average is not the one people write more warmly about.
