Crankshaft
Music discovery that reads your taste, not your data
Crankshaft reads how you actually listen and surfaces songs that fit your real taste — deep cuts included — entirely on your device. No account, no tracking, nothing leaves your phone. Built solo, for Apple Music. A human in the loop instead of an algorithm guessing - and that human is you.

Ahoy, Product Hunt. I'm Justin, and I built Crankshaft over months of nights and weekends off the side of my desk. Nice to meet you all. It began while driving - I had access to all of the music in the world, Apple Music's sound quality was always great, but everything felt very limited and repetitive. I tried to build a smarter shuffle, and it ended up becoming a music that reads how you actually listen, trying to maximize your enjoyment, rather than your engagement. One thing it does differently: it does all of this on your device and collects nothing. No account, no ads, no tracking, no data leaving your phone. Personalization without surveillance. What that gets you: - Discovery that sounds like you, not like the charts — deep cuts and B-sides that actually fit. - Total privacy by design — there's no data to leak because there's no data collected. - A human back in the loop — built by one person who loves music, not a growth team. It's free, it's for Apple Music, and with zero ad spend it somehow found its way to 70 countries — which honestly still floors me. I'd genuinely love this community's take, and I'll be here all day answering anything. Thanks in advance for reading and your interest. It means the world to me.
