# AmpStamp vs Wah Pedal

The clearest difference is in-app purchases: Wah Pedal at none against AmpStamp's 10. Wah Pedal also leads on review sentiment (67% vs 55%). AmpStamp's advantage is update cadence (every 6 weeks vs every 47 months) and rating (4.4 vs 4.2). On price, ratings volume, ads and monetization model there is nothing between them.

Both are free to download. AmpStamp sells 10 in-app purchases, starting at $4.99 per month. Wah Pedal asks for nothing beyond the download.

AmpStamp holds the better App Store score, 4.4 against 4.2. Both are backed by a comparable volume of ratings — 32 and 11 respectively. Written reviews complicate that: 55% of AmpStamp's written reviews are positive against 67% of Wah Pedal's, so the app with the better star average is not the one people write more warmly about.

AmpStamp ships an update every 6 weeks, Wah Pedal every 47 months. The most recent releases landed on November 2, 2026 and November 8, 2026 respectively.
