In our seventh collaboration with Berlin-based musician Hainbach we listen to the stars: Moon Echo is a free to download delay based on a communications technique that uses our closest cosmic neighbor, the moon, as a reflector for radio waves. This results in some rather crunchy and lively echoes, modulated by the movement of Earth and moon. The moon's surface is an imperfect mirror and creates artifacts, unlike any other echo technique. Moon Echo is both a musical lo-fi effect and a playful tool for teaching about space. Available as AUv3 and Standalone.

Verdict
The clearest difference is iOS requirement: M.ETRO at 9.0 against Moon Echo's 12.0. On price, ads, in-app purchases and device support there is nothing between them.
