# AmpStamp vs Tune Labs

The clearest difference is review sentiment: Tune Labs at 100% against AmpStamp's 55%. Tune Labs also leads on in-app purchases (none vs 22) and update cadence (every 3 weeks vs every 6 weeks). AmpStamp's advantage is rating (4.4 vs 3.0) and ratings volume (32 vs 2). On price, ads and device support there is nothing between them.

Both are free to download. AmpStamp sells 22 in-app purchases, starting at $4.99 per month. Tune Labs asks for nothing beyond the download.

AmpStamp holds the better App Store score, 4.4 against 3.0. That said, the two scores are not equally well evidenced: AmpStamp has 32 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 55% of AmpStamp's written reviews are positive against 100% of Tune Labs'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, Tune Labs every 3 weeks. The most recent releases landed on October 29, 2026 and October 22, 2026 respectively.
