Your AI coding agent, in your pocket
CLO2 is an iPhone app that runs and monitors Claude Code sessions on your own Mac or Linux computer — with live token limits, the computer's RAM and CPU temperature, a secrets vault and several computers in one list. It's made for developers who use Claude Code and want to manage their coding agent from their phone, on iPhone (coming soon to the App Store). CLO2 is free to download with a demo; CLO2 Pro (weekly $9.99, monthly $19.99, or yearly $69.99 with a 3-day free trial) is needed to send messages to your computer.
CLO2 lets you start, continue and steer Claude Code sessions that run on your own Mac or Linux computer, from your iPhone. See your token limits, your computer's RAM and CPU temperature, keep secrets in an encrypted vault and drive several machines from one app — with no account and no cloud storage.

What it does
Everything you need, nothing you don't.
Manage sessions from your phone
Every Claude Code session on every paired computer in one list — running, waiting for your answer, or done. Continue one or start a new one in any project folder, send messages while a task runs, stop and send now, compact the context, pin the important ones.
Track your token limits
Your plan's 5-hour and weekly usage left, with reset times, right above the conversation — plus what each reply and each session cost. A notification tells you when a task is done or needs you.
RAM and CPU temperature
See how much memory your computer is using and how hot its CPU runs next to every session, so you notice when a machine struggles before your agent does. See and stop agent processes per computer.
Secrets vault
API keys and passwords stay encrypted on your own computer. The agent uses them by name without printing them, and Face ID guards showing one again.
Many devices, one app
Pair several Macs and Linux machines and see all their sessions together. Same Wi-Fi, Tailscale, or anywhere through an end-to-end encrypted relay.
Private by design
No account and no cloud storage: your code, conversations and files stay on your computer. Pairing needs a code typed on the computer itself, and every message is end-to-end encrypted.
How it works
Install the helper
Run one command on your Mac or Linux computer (shown in the app). It installs the small free CLO2 helper that talks to the Claude Code you already use.
Pair your iPhone
Scan the QR code shown on the computer, or tap the computer in the app and type the code into the dialog on its screen.
Work from anywhere
Open a session, send a message, watch it run, and get a notification when it's done — with your limits, RAM and temperature in view.
CLO2 FAQ
Straight answers about price, devices and privacy.
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?
CLO2 is made by Sakura5, an independent app studio that builds focused, privacy-first apps for iPhone, iPad and Mac. Support: support@sakura5.app.
