What's new in 1.3 You cranked, we listened. • Volume slider right in the player — control the sound without leaving the app. • Previous-track button — tap to restart the song, double-tap to jump back to the last one. • Honest crank feedback — the flame now shows when a track is fully cranked, so you know your love landed. • Smarter Settings navigation — Back now returns to the previous screen, not all the way out. • New "Send Feedback" option in Settings — tell us what to build next. We read every note. Still 100% on your device. Still collects nothing. Thanks for listening with us.
MoreThanks! Novel was what I was hoping for, that’s awfully nice of you to say. Crankshaft reads how you actually listen instead of asking you to rate everything (double thanks for taking the time to write this, in context). If you hit anything you don’t like, I’m all ears, this is a one-person project, real feedback shapes it directly. Thanks for giving it a try! -Justin
