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.

Verdict
The clearest difference is price: Relativity Widget at Free against Screen Test Utility's $1.99. Relativity Widget also leads on rating (5.0 vs 4.0) and update cadence (every 6 months vs every 24 months). Screen Test Utility's advantage is ratings volume (8 vs 1). On ads, in-app purchases and device support there is nothing between them.
