StepShift - Run Into The Future description
Special relativity tells us that things moving at faster velocities experience time slower. So if you were to walk or run, theoretically you would be moving at a faster velocity. Using human averages for walking distances and speeds this app tracks your steps and tells you how many femtoseconds in the future you are!
I, the creator of this app, Sathira Katugaha, am a high school student who made this as a fun project for others to enjoy after I learned about special relativity. So please, enjoy it!
