UsageWatchYour AI quota, at a glance.
See Codex and Claude Code quota left and the next reset on iPhone, iPad, home screen widgets and Apple Watch.
UsageWatch is an independent iPhone, iPad and Apple Watch app that shows how much Codex and Claude Code quota you have left in the 5-hour and weekly windows, and when each one resets, so you can check before you start a session.
Check before you start, not while you’re stuck
In a terminal, /usage or /status tells you what’s left. But the moments you plan your work are usually away from the terminal. That’s when a glance at your phone or wrist helps.
Morning check
See how much of each window is left and when it resets before you open your laptop.
Before a long session
Make sure there’s enough room in the 5-hour and weekly windows to finish what you start.
