See the AI usage your Mac reads, right on your iPhone.
UsageMaster for iPhone is a companion app that shows the usage of AI tools such as Claude Code, Codex, and Gemini CLI, as read by UsageMaster on your Mac, delivered through iCloud. No sign-in and no extra setup: sign in to iCloud with the same Apple Account on both devices and they connect automatically.
◆ Features
• Instant iCloud sync: when a value changes on your Mac, it reaches your iPhone right away
• 5-hour and weekly limits with reset times, on a single card
• Token usage and estimated cost in daily charts
• Home Screen and Lock Screen widgets to check without opening the app (Pro)
• Alerts when a limit resets and when a new AI model arrives
• A calm, paper-like design with Light and Dark modes
◆ Privacy
• Only usage numbers travel through iCloud. Tokens, emails, and file paths are never uploaded.
• The iPhone app never signs in to your AI tools and never handles credentials.
◆ Pro
The free plan shows up to three AI tools. Lifetime Pro is a one-time purchase (not a subscription) that unlocks every AI tool and the widgets, and works on the Mac and iPhone signed in with the same Apple Account. Try it first with the free 7-day trial pass from the App Store. Prices may vary by region.
◆ Good to know
• UsageMaster for Mac (Mac App Store) must be running for new values to arrive.
• If nothing has arrived from your Mac yet, tap "Explore with sample data" to look around first.
