# Equalizer Fx vs Trapp

The clearest difference is monetization model: Trapp at free with in-app purchases against Equalizer Fx's subscription. Trapp also leads on ads (none vs shown) and iOS requirement (9.3 vs 15.0). Equalizer Fx's advantage is update cadence (every 3 weeks vs every 6 months) and ratings volume (28K vs 3.9K). On price, rating, review sentiment and in-app purchases there is nothing between them.

Both are free to download. Equalizer Fx sells 10 in-app purchases, starting at $2.99 per 7 days and Trapp sells 3 in-app purchases, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.2 for Equalizer Fx against 4.2 for Trapp. That said, the two scores are not equally well evidenced: Equalizer Fx has 28K ratings behind it against 3.9K, so its average is the more settled of the two. Written reviews are what separate them: 25% of Equalizer Fx's written reviews are positive against 21% of Trapp's.

Equalizer Fx ships an update every 3 weeks, Trapp every 6 months. The most recent releases landed on October 28, 2026 and October 22, 2026 respectively.
