Claude Double Checker — Is 2× active?

See Claude's 2× usage window live in your macOS menu bar

If you use Claude Code a lot, you know about the 2× usage window — but keeping track of when it's active, how long it lasts, and when it switches back is a pain. I built a small macOS menu bar app that shows you exactly that, right in your menu bar. Know when to push hard and when to hold back. Free download at double.raphaelduhs.at — happy building!
