Tapeworm is a tape echo with a unique method of changing the delay time, and a wiggly, dirty sound. You can set the delay time manually by stretching the worm. The record button will flash to show the current interval. You can exit the fixed time mode and enter free mode by toggling. This lets the delay time change randomly, which you can encourage by flicking the tapeworm around. Double tap to reset, adding a fun performative element to your sound. Feedback can be overdriven. An analog-modeled tape saturation and compression, and amplifier and limiter stage, keep it sounding juicy when it gets loud. Tapeworm is audio unit (AUv3) compatible, meaning you can use it as a plugin in your app of choice like AUM, GarageBand or Logic. We hope you enjoy using tapeworm for music, or just for fun.

tapeworm holds the better App Store score, 4.3 against 3.1. That said, the two scores are not equally well evidenced: D0TS Echoplex has 412 ratings behind it against 12, so its average is the more settled of the two. Written reviews complicate that: 73% of D0TS Echoplex's written reviews are positive against 71% of tapeworm's, so the app with the better star average is not the one people write more warmly about.
D0TS Echoplex ships an update every 11 months, tapeworm every 2 weeks. The most recent releases landed on September 20, 2026 and August 19, 2026 respectively.
