ClaudeWatch

Note for users downloading from GitHub Releases: macOS may show a security warning because the app is not signed with an Apple Developer certificate. To open the app:

1. Try to open the app (it will be blocked)
2. Go to System Settings → Privacy & Security
3. Scroll down and click "Open Anyway" next to the ClaudeWatch message
4. Click Open in the confirmation dialog

A beautiful macOS menu bar app that displays your Claude Code usage statistics in real-time. Monitor your session and weekly limits at a glance with a stunning glassmorphic UI.

Features

Real-time Usage Tracking — Session, weekly (all models), and weekly (Sonnet) percentages in the menu bar at a glance Last 24h Insights — Fully dynamic behavioral signals parsed live from /usage (long sessions, high context, subagent-heavy runs) with collapsible descriptions Independent Reset Countdowns — Each tier shows its own reset timestamp plus a live "in Xh Ym" countdown Dynamic Plan/Model Detection — Header reflects the actual plan and model reported by the CLI (Claude Max, Pro, Team, etc.) — nothing hardcoded GitHub Release Auto-Check — Polls GitHub on launch; a banner appears when a newer build is available with a one-tap Download button Dynamic Color Indicators — Progress bars transition green → amber → red based on usage level Configurable Auto-refresh — 30s / 1m / 2m / 5m / 10m / Never Zero Token Usage — Reads account stats locally via the Claude CLI; never invokes a model

Requirements

System Requirements

Requirement	Version	Notes
macOS	13.0 (Ventura) or later	Required for SwiftUI features
Python	3.6+	Usually pre-installed on macOS
Xcode	14.0+	Only needed if building from source

Claude Requirements

Requirement	Description
Claude Code CLI	Must be installed and accessible. Install from claude.ai/code
Claude Pro/Max	Active subscription required (usage limits only apply to paid plans)
Authenticated	Must be logged into Claude Code CLI (claude command should work)

Verify Requirements

# Check Python version
python3 --version

# Check if Claude CLI is installed
which claude

# Test Claude CLI is working
claude --version

Installation

Option 1: Download Release (Recommended)

1. Download the latest .app from Releases
2. Move ClaudeWatch.app to your Applications folder
3. Open the app (you may need to right-click → Open the first time due to Gatekeeper)

Option 2: Build from Source

1. Clone this repository:

   git clone https://github.com/JohnDimou/ClaudeWatch.git
   cd ClaudeWatch

2. Open in Xcode:

   open ClaudeWatch.xcodeproj

3. Build and run (⌘+R)

Or build from command line:

xcodebuild -project ClaudeWatch.xcodeproj -scheme ClaudeWatch -configuration Release build

The built app will be in ~/Library/Developer/Xcode/DerivedData/ClaudeWatch-*/Build/Products/Release/

Usage

1. Launch the app - A brain icon appears in your menu bar with usage percentages
2. View quick stats - The menu bar shows session and weekly usage
3. Click for details - Opens a popup with full usage information
4. Configure settings - Click the gear icon to adjust refresh interval

Menu Bar Display

🧠 25% | 22%
   ↑      ↑
   │      └── Weekly usage (all models)
   └── Current session usage

Color Indicators

Usage Level	Color	Meaning
0-50%	Green	Plenty of capacity remaining
50-75%	Yellow/Orange	Moderate usage
75-100%	Red	Near or at limit

Settings

Access settings by clicking the gear icon in the popup:

Setting	Options	Default	Description
Refresh Interval	30s, 1m, 2m, 5m, 10m, Never	1 minute	How often to auto-fetch usage data
Refresh on Open	On/Off	On	Fetch fresh data when popup opens

Settings are persisted and remembered between app restarts.

How It Works

The app uses a Python script to interact with the Claude Code CLI:

1. Spawns Claude CLI in a 200-column pseudo-terminal (pty) so the /usage box renders fully
2. Sends the /usage slash command and waits for the "Last 24h" section to appear as the signal that rendering is complete
3. Parses the terminal output structurally — section boundaries are detected by the last occurrence of each header, and insights are extracted purely by their NN% pattern with no hardcoded wording
4. Displays the results in a native SwiftUI interface

Update Checking

On launch (and on popover open, respecting a 6-hour cache) the app queries api.github.com/repos/JohnDimou/ClaudeWatch/releases/latest, compares tag_name against the installed CFBundleShortVersionString using a semver compare, and surfaces a banner when a newer stable release is published. The user taps Download to open the release page in their browser — the app never attempts an in-place install (this distribution is unsigned, so Gatekeeper would reject any automated replace).

Important: No Token Usage

This app does NOT consume any Claude API tokens. The /usage command is a built-in CLI feature that queries your account statistics directly from Anthropic's servers - it does not invoke any AI model. It's equivalent to checking your usage on the Anthropic dashboard.

Troubleshooting

"Claude CLI not found"

# Check if Claude is installed
which claude

# If not found, install from:
# https://claude.ai/code

# If installed but not found, it might be in a non-standard path
# The app checks these locations automatically:
# - /usr/local/bin/claude
# - /opt/homebrew/bin/claude
# - ~/.local/bin/claude
# - ~/.npm-global/bin/claude

"Python 3 not found"

# Check Python version
python3 --version

# If not installed, install via Homebrew:
brew install python3

Usage not updating

• Click the refresh button (circular arrow) in the popup
• Check Settings → ensure refresh interval isn't set to "Never"
• Ensure you have an active Claude Pro/Max subscription
• Verify claude works in your terminal

App won't open (macOS security)

• Right-click the app → Open → Open
• Or: System Settings → Privacy & Security → Open Anyway

Usage shows 0% for everything

• Make sure you're logged into Claude Code CLI
• Run claude in terminal and verify it works
• Check that you have a Pro/Max subscription

Unexpected permission prompts (Photos, Music, Desktop, etc.)

If you see macOS permission dialogs asking for access to Photos, Music, OneDrive, Desktop, or other folders:

• This should not happen with v1.2.0+ - we fixed issues where the subprocess could trigger these prompts
• Try downloading the latest release
• If the issue persists, please open an issue with:
  • Screenshot of the permission dialog
  • macOS version
  • App version
  • Any relevant details about your setup (iCloud sync, OneDrive, etc.)

Privacy & Security

• Local Only - All data stays on your machine
• No External Servers - The app only communicates with the local Claude CLI
• No Tracking - No analytics or telemetry
• Open Source - Full source code available for review
