What do I need?
A Mac with macOS 26 or later and Claude Code, Codex or Antigravity CLI installed and signed in. iPhone and Apple Watch show readings from your Mac through the same iCloud account.
What can I use for free?
Limits, your current session, notifications and Siri are free. On Mac, widgets, advice, API-price estimates and history are also free. On Apple Watch, the app, its four layouts and the Light. With Pro, the top card changes layout on iPhone and the Mac, and the gauge colours and the Light can be set. Reading current quotas via MCP is free from Mac 0.5.15. Pro adds advanced features on iPhone and Apple Watch, and features for your assistants on Mac.
Which services are supported?
Claude (Pro and Max) and Codex (ChatGPT Plus, Pro, Go and Business), on equal terms. In Settings › Services, each one switches on or off; JaugeAI detects Codex as soon as the ChatGPT or Codex app is installed on the Mac. On Mac, Gemini too, through Antigravity CLI (“Gemini models” and “Claude and GPT” quotas). GitHub Copilot is planned.
My iPhone says “No reading”.
Install the Mac app and sign in to Claude Code (claude auth login) or Codex (in the ChatGPT app or with codex login). Check that the Mac and the iPhone use the same iCloud account with iCloud Drive on, and keep the Mac awake.
macOS asks for keychain access.
Only in full mode, and it normally never does: JaugeAI reads Claude Code’s entry the way Claude Code itself does, with no password and no “Always Allow”, even after an update. If macOS asks anyway, choose “Always Allow”.
Do I need a subscription?
Yes: a Claude Pro or Max plan, or a ChatGPT plan that includes Codex (Plus, Pro, Go or Business), or Gemini with Antigravity CLI, with the coding tool installed and signed in on the Mac. JaugeAI shows those plans’ limits; it replaces and changes nothing.
How do I unlock JaugeAI Pro on the Mac?
Buy JaugeAI Pro on the Mac (€9.99, licence by email, opened in the app; lost licence: licence.jaugeai.com/retrouver) or in the iPhone app. An iPhone purchase goes through your iCloud: with the same Apple Account, open the iPhone app once, and the Mac unlocks automatic instructions, advanced MCP analysis, gauge colours and the Light, layouts, the JaugeAI band in Claude Code and the voice connector for ChatGPT and Claude. The gauges stay free on the Mac; current quota checks and reset times through MCP are free from Mac 0.5.15.
Why not the Mac App Store?
To measure your limits, JaugeAI reads Claude Code’s and Codex’s files on your Mac as they change, and can tell your coding agents what they have left. Mac App Store apps are not allowed to access other apps’ files: JaugeAI would lose what matters most. The app from this site is signed and checked by Apple (notarized), and updates itself. On iPhone and Apple Watch, JaugeAI is on the App Store.
I don’t have a Mac.
JaugeAI needs a Mac to read your limits: your iPhone and Watch show what it shares. Without a Mac, the iPhone app offers sample data.
The Unlock button is greyed out.
The App Store isn’t answering right now: try again later, or use “Restore Purchases”.
