SNRatio
Signal over noise for your agents.
SNRatio puts every Claude conversation on one board. Each one reports progress, what’s done and what needs you. You answer from your Mac, soon from your iPhone too, and nothing risky runs without your Touch ID.
Many Claudes. One place to answer them.
You start conversations wherever you like. SNRatio is where they come back to you, in order of who has the turn.
Every Claude reports in
Each conversation posts progress, done and “needs you” through the SNRatio tools. No copy and paste.
One board, your turn first
Orange means it waits on you. Blue means Claude has it. Green means done. Everything else stays quiet.
Reply from anywhere
Type or dictate on your Mac, or soon answer on your iPhone. One listening session picks it up in seconds.
It delegates. You sign.
The listener hands work to subagents in their own worktrees. Deploys, merges, sends and money wait for your signed OK.
Built for the way you already work with Claude.
One board for every conversation
A topic per piece of work, with its whole thread. Today shows what matters now; the rest waits one click away.
Signed approvals
Risky steps need Touch ID, Apple Watch or Face ID. The device signs the exact action, and it runs exactly once.
Missions
Give Claude a goal. It proposes the agents, builds them, measures them and keeps an overview you can skim.
Dictation, on-device
Hold Control anywhere in SNRatio and talk. Speech is transcribed on your Mac and never leaves it.
Delegation that inherits your rules
One listening session reads your replies and hands work to subagents, each in its own git worktree, behind a hook that stops risky commands.
iPhone and iPadSoon
The same board in your pocket, with notifications when something needs you and Face ID for approvals.
Lives in the menu bar
A native Mac app, light and dark. One click from anywhere, keyboard first, and quiet until it’s your turn.
Attachments and screenshots
Paste a screenshot, drop a PDF or link a doc into any topic. Claude reads it where the conversation is.
Updates on their own
New versions download in the background and install when you quit. Signed and notarized.
Three steps. About two minutes.
At the end you have the same setup the app was built with: every Claude reporting to one board, and you answering from wherever you are.
Drag it to Applications
Download the app, open the zip and move SNRatio into your Applications folder.
Follow the onboarding
SNRatio walks you through each switch: notifications, the listener, approvals with Touch ID.
Connect Claude
Onboarding registers the SNRatio tools with Claude Code for you. This is what it runs:
claude mcp add snratio --scope user -- "/Applications/SNRatio.app/Contents/Helpers/signals-mcp"
Step away. Keep the work moving.
Your agents don’t stop when you leave the desk, and now neither do your answers.
- A notification only when it’s your turn. Progress stays on the board.
- Reply in the topic. The listening session on your Mac picks it up.
- Approve with Face ID. Same signed approval, same “runs once”.
iOS 17 or later. About the iPhone app
Your board lives on your Mac.
Local-first. Your board lives on your Mac; sync is optional (SNRatio Cloud, coming soon).
FAQ
How do you say SNRatio?
“S-N ratio”, as in signal-to-noise ratio. The app’s job is to raise yours: the few things that need you, out of everything your agents are doing.
Which Claude does it work with?
Claude Code, in the terminal, the desktop app or your editor, and the Claude desktop app. SNRatio adds its tools through MCP, so any conversation with them installed can report to the board.
The listening session, the one that picks up your replies and delegates, runs in Claude Code.
What does it cost?
SNRatio is free during the beta. It uses your existing Claude plan; SNRatio never sees your Claude credentials.
What is the waitlist for?
We’re letting people in a few at a time so every new account gets a working setup. Leave your email and we’ll write once, when your spot opens. The same list covers the iPhone app.
The email is stored only to send that invite. No newsletter, no tracking.
What counts as a risky step?
Anything you can’t take back: deploys, merges, migrations, sending email or messages, deleting things, moving money. A hook stops those commands and posts an approval card. Once you approve with Touch ID, Apple Watch or Face ID, that exact action runs once. Nothing else gets through on the same approval.
What do I need?
A Mac with macOS 14 Sonoma or later and Claude Code. The iPhone and iPad app, coming soon, needs iOS 17 or later.
Do I have to keep a Claude session open?
For replies to be picked up right away, yes: one listening session. SNRatio shows at the top of the board whether Claude is listening, and your messages wait in the topic until a session picks them up.
Less noise. More signal.
