Mac Menu Bar App for Claude Code & Codex Usage

I sell a MacOS menu bar app to help users track their AI token usage in Claude Code & Codex.

In plain English

Soren Starck sells a Mac app that sits in the strip of icons at the top of the screen and tracks how much paid AI use someone has spent in the coding tools they already run. People who write software buy it because hitting that limit in the middle of a task is frustrating. Billing and the other routine parts of running the app are mostly handled for him. Soren still checks quality, answers users, shares the app with other builders, and deals with unusual cases.
