What CLO2 does

CLO2 is an iPhone app for Claude Code users. It pairs with a small free helper on your Mac or Linux computer and lets you manage Claude Code sessions from your phone: start or continue a session, send messages and photos, see live token limits, your computer's RAM and CPU temperature, keep secrets in an encrypted vault, and use several computers at once — over Wi-Fi, Tailscale, or an end-to-end encrypted relay.

Getting started

  • Install the helper: on your Mac or Linux computer run curl -fsSL https://clo2.synthvale.com/install.sh | bash. You need Claude Code installed and signed in on that computer.
  • Pair: run clo2 pair and scan the QR code with the CLO2 app, or tap your computer in the app and type the 4-digit code into the dialog on the computer.
  • Try it first: tap “Try the demo” on the first screen — no computer needed.

Frequently asked

  • What needs Pro? Sending messages and starting sessions on your computer. Pairing, browsing sessions and transcripts, the status line (token limits, RAM, CPU temperature) and the demo are free.
  • How much is Pro? $9.99 per week, $19.99 per month, or $69.99 per year with a 3-day free trial.
  • How do I cancel? Subscriptions are billed and managed by Apple: Settings → your name → Subscriptions → CLO2 → Cancel Subscription, at least 24 hours before the period ends. Refunds are requested from Apple at reportaproblem.apple.com.
  • I paid but it's locked / new iPhone. Open Settings → CLO2 Pro → Restore Purchases with the same Apple ID.
  • Does it work away from home? Yes — directly on the same Wi-Fi, over Tailscale, or anywhere through the encrypted relay.
  • Remove a phone or the helper: clo2 devices / clo2 revoke NAME on the computer; clo2 uninstall removes the helper (your data in ~/.clo2 stays until you delete it).

Common questions

  • Restore a purchase: open the app's paywall and tap “Restore Purchases”.
  • Manage a subscription: iPhone Settings → your name → Subscriptions.
  • Bug or feedback: email us with your device model and iOS version.

CLO2 will be on the App Store soon.

Frequently asked questions

Do I need a Mac?

You need a Mac or Linux computer with Claude Code installed and signed in. CLO2 pairs with a free helper you install there with one command. You can try the built-in demo without a computer.

Is my code sent to your servers?

No. Sessions, conversations and files stay on your computer. Messages between your iPhone and computer are end-to-end encrypted; the relay can't read them.

Does CLO2 work over Tailscale?

Yes. CLO2 connects directly on the same Wi-Fi, over Tailscale, or anywhere through an end-to-end encrypted relay.

Is CLO2 made by Anthropic?

No. CLO2 is an independent app by Sakura5. Claude and Claude Code are trademarks of Anthropic; you use your own Claude Code installation and Anthropic account.

Who makes CLO2?
