# AmpStamp vs Overloud THU

The clearest difference is update cadence: Overloud THU at every 11 days against AmpStamp's every 2 months. Overloud THU also leads on ratings volume (97 vs 32). AmpStamp's advantage is rating (4.4 vs 4.1). On price, review sentiment, ads and in-app purchases there is nothing between them.

Both are free to download. AmpStamp sells 22 in-app purchases, starting at $4.99 per month and Overloud THU sells 35 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

AmpStamp holds the better App Store score, 4.4 against 4.1. Both are backed by a comparable volume of ratings — 32 and 97 respectively. Written reviews complicate that: 55% of AmpStamp's written reviews are positive against 60% of Overloud THU's, so the app with the better star average is not the one people write more warmly about.

AmpStamp ships an update every 2 months, Overloud THU every 11 days. The most recent releases landed on August 17, 2026 and September 21, 2026 respectively.
