Usage for Claude + ChatGPT 4.0

Version 4 is a big one. Usage for Claude now tracks ChatGPT accounts too, with your Codex session and weekly limits next to Claude's. See every account at once in three styles (Minimal, Detailed, Chart), put several in the Mac menu bar, and keep them on iPhone, iPad, Apple Watch and widgets. Alerts tell you before you run out, and the history shows where your week went. You sign in on the official Claude and ChatGPT pages, and your data stays in your own iCloud. Free, with Pro extras.
