About

I’m an indie mobile app maker building 12 apps in 12 months. I like making slightly unusual ideas real — things that are simple to use but have a strange idea underneath. Currently, I’m building SIXTY · 60: type in a date, and hear what that day sounds like.

SIXTY · 60 - Turn any date into music.

SIXTY turns any date into a short piece of music, worked out on your phone. Your birth date and hour shade the notes, so the same day sounds different for you than for anyone else. Sixty days make a full cycle.
