Relativity Widget vs AVR Link

Relativity Widget allows you to visualise Einstein's theories of relativity right on your home screen. Two modes : • Special Relativity: imagine that you are in a spaceship travelling at a chosen speed. If you travel fast enough, time will pass differently on earth... • General Relativity: you are on earth while a friend of yours went on a journey, in a spaceship, at a chosen distance to a Schwarzschild black hole. If you are close enough, time will pass differently in the spaceship... Relativity Widget clocks represent the difference in time flow, since midnight, between a high speed / high gravity experiencing reference frame and a low speed / gravity one, according to Einstein's theory of relativity.

AVR Link gives you fast, convenient control of your compatible AV receiver from your Mac, iPhone, and Apple Watch. Designed with the Marantz AV 10 in mind, AVR Link also works with compatible Denon and Marantz AV receivers that support local-network control over Telnet.
