For people cooking with AI
You should not have to wonder whether the next prompt will go through. Headroom keeps a live measure of your remaining usage, right where your attention already is.
AI plans come with 5-hour windows, weekly windows, and opinions about when you've had enough. The rules change without notice, too. Headroom watches what your providers actually enforce, so you can stop tab-switching to usage pages.
While you're working it shows one big number: percent left on the meter you're actually burning, from your last-used model's tightest window, 5-hour or weekly, whichever bites first. Idle, it settles into twin bars with your tightest session on top and tightest week below.
An optional strip beside the Windows clock or in the macOS menu bar: every account, always visible. It offers three densities on Windows and automatically compacts around the camera housing on notched Macs.
Per-account cards with every limit the provider actually reports. Reset countdowns, pace ticks that show whether you're burning fast or coasting, credits and spend where they exist.
Built around one rule: never show a confident number that isn't true.
One warning at your threshold, one at critical. Six-hour cooldown per quota, escalations break through, stale data never notifies.
Signed releases, checked quietly, installed in one click from the flyout. You bought it once. It keeps getting better.
A tick marks where an even burn would put you. One look tells you “coasting” or “burning fast” before the math does.
Multiple accounts per provider. Drag them into the order you think in. The status icon, deck and flyout all follow.
Give an API key a monthly budget and spend becomes a draining meter, the same instinct as your subscription limits.
Your credentials never leave your computer. Headroom talks to your providers directly, keys stay in Windows Credential Manager or the macOS Keychain, and your usage is nobody's business but yours.
Subscriptions and API accounts, each read from the provider's own numbers, never guessed from token counts.
AntigravityAgent model quotas & reset timesNew provider adapters ship as updates, and your license already covers them.
The phone reads your providers itself, then puts what's left where you already look.
Every window for every account you connect, worst first, with the pace ticks and reset countdowns the desktop app draws.
Home Screen in three sizes, Lock Screen, StandBy, and a Glance widget on Android. Whatever runs out soonest leads.
A Watch app and complications, fed by your iPhone. The ring says which provider, the number says what is left.
Your own thresholds, a nudge before a limit bites and another when it refills. Android adds a Quick Settings tile and a permanent meter in the shade.
Headroom for iOS needs iOS 17 or later. The Android app needs Android 9 or later.
Cheaper than the hour you lost the last time a limit surprised you. A desktop license carries the phone and watch apps with it.

Buy once, get a key by email, paste it into Settings → License. One key keeps one device active. Deactivate on an old machine and activate on a new one whenever you like. Every future update is included.
Headroom stops refreshing your meters until you activate a license. Your settings and accounts stay exactly where you left them.
Headroom is a new, independently published app, so SmartScreen may show “unknown publisher” until the installer builds reputation. Updates are cryptographically signed and verified by the app before installing.
API keys go into Windows Credential Manager or the macOS Keychain, not config files. Provider cookies stay inside per-account isolated profiles on your machine. Nothing usage-related leaves your computer except the provider requests themselves.
No, if you already bought Headroom. Activate the iPhone or Android app with the same license key and it costs nothing, on up to three devices. On its own the mobile app is a $2.99 one-time unlock. The Apple Watch app ships inside the iPhone app either way.
Nearly all of it. The phone signs in to each provider itself, over the same endpoints, so Claude, Codex, Cursor, Copilot, Gemini, DeepSeek and the API accounts all report the same numbers. Two providers are desktop-only for now: Grok's weekly usage and Antigravity, because neither exposes an endpoint a phone can reach.
Yes. The universal installer supports Apple silicon and Intel Macs running macOS 14 or later. The same license can be moved between Windows and Mac whenever you like.
