Echo effect Audio Unit V3 inspired by the mayan pyramids acoustic echo. I come up with a complex phase modulated frequency of the echo so you can change it’s frequency signature. It is kind of changing the material of the reflective surface and I called it “Stone F”. I have made the echo to sound more music friendly to me but there is button called “UFO” and if you press it the effect is more close to the mayan just shifting the frequency backwards (I liked that better). You can also control the feedback of the phase modulation. The effect can work as a stand alone app and as an audio unit AUV3 plug-in. Stone Echo is an effect that is heavy on the CPU Controls: - Time - time offset of the echo - Stone F - frequency response of the echo - Feedback - echo feedback - Level - the volume of the echo - UFO - heavy modulated echo

Verdict
The clearest difference is update cadence: Overdrive Pedal at every 3 weeks against Stone Echo's every 38 months. Overdrive Pedal also leads on price ($0.99 vs $2.99). Stone Echo's advantage is iOS requirement (10.0 vs 17.4). On ads, in-app purchases and device support there is nothing between them.
