Instead of a pedometer — Einstein’s “time drift.” A grand thought experiment (Gedankenexperiment) you can carry in your pocket. The formulas are real. The measuring is rough GPS. Walk. Take the train. Climb the stairs. Just living as usual already opens a tiny gap between you and “the you who stayed where you woke this morning.” Relativity Meter is an everyday toy for peeking at that stretch and squeeze of time hidden in a day’s steps — blown up to the absurd scale of × 10⁻¹⁴ seconds. • Blue = time slows (speed: special relativity) • Red = time advances (height: gravitational redshift) • The number on the home screen = today’s net drift from both We use Einstein’s equations as they are: Δt ≈ t·v²/(2c²) from special relativity (speed), and Δt ≈ t·gh/c² from general relativity — gravitational redshift (height). The sensor side is phone GPS. Not a lab instrument — a toy for finding wonder in ordinary steps. Privacy you can trust No account. Fully offline. Location is computed on-device only and is never sent to any server. (On Apple Watch, you can glance at today’s number on your wrist.) Optional dial-face pack The digital dial stays free.
