You're viewing a private link. Cipher is currently in private beta — shared only with a select group of musicians and collaborators. It's not publicly listed or advertised anywhere. If someone sent you this, they thought you should see it.

Everyone in this private beta will be personally shouted out when Cipher launches publicly.

One chart. Every key.

The number system, finally given a home.
Musicians have used the Nashville Number System for decades — writing 1, 4, 5 instead of C, F, G. It works in any key, any style, any genre. But until now, there was no dedicated tool built around it. Cipher changes that.

Write in numbers, play in any key

Type your chart in numbers. Toggle to chord view and Cipher instantly translates everything to real chord names in whatever key you need. One chart works everywhere.

Built for the stage

Manage your setlists, set per-song keys for different singers, navigate between songs with keyboard shortcuts, and export stage-ready PDFs — all without touching the internet.

Quick Input — chart a song in minutes

Open Quick Input, type your chart while the song plays, hit Parse. Cipher builds the full formatted chart instantly. A full Sunday set charted in under 20 minutes.

Quotes from beta testers coming soon.

Cipher is not publicly available yet.

This is a private beta. The app is fully functional and being used by working musicians right now — but it's not listed on any app store, not advertised anywhere, and not open to the general public. If you're seeing this, you received this link directly.


Cipher is being built by one person — Joe Davis. Things will get missed. Bugs will exist. That's exactly why you're here. Your feedback directly shapes what gets fixed, what gets added, and what ships at launch.


Everyone who participates in this private beta will be personally shouted out when Cipher launches publicly. Your name, your city, your instrument — acknowledged.
