Headroom Mobile

Headroom for iPhone is the pocket companion to Headroom for Mac — the menu bar
app that shows how much of your Claude and Codex subscription usage remains.

Your Mac reads the numbers. Your iPhone shows them. Glance at your Home Screen
and know whether you have room for one more session before the weekly window
resets.

WHAT YOU SEE
• Claude and Codex side by side, as equals — session and weekly windows with
percentage remaining
• Reset times, exactly as the providers report them
• Plan renewal dates, plus optional API spend totals if you track them on
the Mac
• Freshness at a glance: every screen says when the numbers last updated

WIDGETS THAT RESPECT A GLANCE
Small, medium, and large Home Screen widgets in the same design as the app —
readable percentages, clean bars, no decoration competing with the number you
came for.

PRIVATE BY ARCHITECTURE
Your Mac publishes a usage summary through your own iCloud account, and your
iPhone reads it. That summary is percentages, reset labels, and timestamps —
never credentials, API keys, or account details. Headroom has no servers, no
accounts, no analytics, and nothing to sell. The full policy is one page:
headroom.zantos.co/privacy

REQUIRES THE MAC APP
Headroom for iPhone is a companion display. It needs Headroom for Mac
(free download at headroom.zantos.co) running on a Mac signed into the same
iCloud account, with "Sync snapshot to iPhone" switched on. Without it, the
app will wait politely — but it will wait.

Built for people who live in Claude Code and Codex all day and just want to
know: how much headroom is left?
