# BIAS AMP 2 vs VStomp Amp

BIAS AMP 2 and VStomp Amp both sit at 4.4 stars, but that hides the real split: 75% of VStomp Amp's written reviews are positive against 50% of BIAS AMP 2's. VStomp Amp also leads on iOS requirement (9.0 vs 11.0). BIAS AMP 2's advantage is ratings volume (651 vs 11). On price, rating, update cadence and ads there is nothing between them.

Both are free to download. BIAS AMP 2 sells 9 one-off in-app purchases and VStomp Amp sells 10 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

BIAS AMP 2 holds the better App Store score, 4.4 against 4.3. That said, the two scores are not equally well evidenced: BIAS AMP 2 has 651 ratings behind it against 11, so its average is the more settled of the two. Written reviews complicate that: 50% of BIAS AMP 2's written reviews are positive against 75% of VStomp Amp's, so the app with the better star average is not the one people write more warmly about.

BIAS AMP 2 ships an update monthly, VStomp Amp every 2 months. The most recent releases landed on November 1, 2026 and November 3, 2026 respectively.
