Your AI friends' limits, straight from the Agent Cat on your Mac — now on iPhone. Codex Ā· Claude Ā· Gemini — check the remaining limits and usage your desktop Agent Cat keeps in sync, wherever you are. • Home Screen widgets — rotating cards for every connected AI friend, mascot included • Lock Screen Ā· Dynamic Island — your tightest limit as a Live Activity • Apple Watch — remaining limits on your wrist, alerts included • Limit alerts — when your Mac spots a depleted limit, your iPhone gets the push • Usage trends — 7-day token usage, provider share, Codex reset outlook • Multiple accounts — two accounts on one provider stay separate and accurate Agent Cat Mobile is the companion app for Agent Cat on macOS and Windows. Prompts, code, and file paths are never collected — only limit percentages and usage aggregates are synced. Which limits appear depends on your desktop app. The Mac and Windows apps from agentcat.app send every connected provider's limits; the Mac App Store version sends Codex limits and usage for all agents. To get started, sign in to Agent Cat on your Mac and turn on Cross-device sync in Account, then sign in with the same account on iPhone.

About

AgentHeadroom

Headroom for your agent quota. AgentHeadroom reads the usage limits on the AI accounts you already have, shows how fast you are spending them, and keeps the numbers current on the Lock Screen, in widgets, on iPad and in your Mac's menu bar — without opening anything. REFRESHED FROM ANYWHERE Each of these refreshes, and updates the widgets and the Live Activity: • A Control Center button, even when locked • A Lock Screen button, the Action button, Siri or a Shortcut • Automations: when you open Claude, ChatGPT or Codex, when the device goes on charge, or at a time of day • The refresh button on a widget, or the Live Activity's arrow, which can start the Live Activity with the app closed • On its own in the background, as often as iOS allows ON THE LOCK SCREEN, WITH THE APP CLOSED A Live Activity counts your five-hour window down to the second, with the spend it was last read at and how fast it is moving — and says so when the window resets. WHAT IT SHOWS • Every window at once — five-hour, weekly, and per-model — as a ring • Whether you are on pace, ahead, or burning, measured against the clock • A projection: at this rate, do you run out before the window resets? • Usage credits, in money • Counted from either end: what you have used, or what is left • Notifications for a threshold crossed, a reset ahead of schedule, and a session that needs signing in again WIDGETS Small, medium and large Home Screen widgets, and Lock Screen widgets, each on the account you choose. IPHONE, IPAD AND MAC One purchase for all three. On iPad: a readable column, every orientation, Split View and Slide Over. On the Mac: a menu bar item, a menu and desktop widgets. Turn on Share accounts with the Mac and your accounts arrive there through your iCloud Keychain — the Mac never signs in. Turn on Wake from Mac and the Mac nudges the phone the moment usage moves. FREE, AND PRO Free is one account with every feature. Pro adds as many accounts as you like, and accounts you already have keep working whatever happens: • AgentHeadroom Pro (Lifetime) — $14.99, paid once • AgentHeadroom Pro (Annual) — $7.99 a year, auto-renewing PRIVACY AgentHeadroom collects nothing. It has no server to collect it with. • Your usage numbers, and nothing else. Your conversations, your prompts and your code are never requested and never seen. • Your sign-in stays on this device, in the iOS Keychain, and never syncs or migrates from a backup. With Share accounts with the Mac on, it is kept in your iCloud Keychain instead — end-to-end encrypted, readable on your devices only, never seen by us — until you turn sharing off. • There is no AgentHeadroom account. No server, no sign-up. Two things go through Apple's iCloud, both yours to switch off: the sign-ins you share, in your iCloud Keychain, and while Wake from Mac is on, a one-line nudge from your Mac in your own iCloud account that says usage moved and carries no reading. • No analytics, no ads, no crash reporter. • Deleting an account erases its session, its readings and its history straight away. • You can check all of this. Point a network proxy at your phone and watch — the only hosts AgentHeadroom ever contacts are the providers whose accounts you added. AgentHeadroom is not affiliated with, endorsed by, or sponsored by any AI provider. Provider names appear only as labels for accounts you added yourself. TERMS Payment is charged to your Apple Account at confirmation of purchase. AgentHeadroom Pro (Annual) is a $7.99 auto-renewing subscription with a term of one year. It renews automatically unless auto-renew is turned off at least 24 hours before the end of the current period, and your Apple Account is charged for renewal within 24 hours of the period ending. Manage or cancel it in your Apple Account settings. AgentHeadroom Pro (Lifetime) is a one-time purchase of $14.99 and does not renew.
