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!




This is one of those tiny tools that is way more useful than it sounds at first. If you use Claude Code a lot, knowing exactly when the 2× window is active can genuinely change how you pace your work. I also like that it stays lightweight and does just one thing.
Curious, did you build this mostly for yourself at first, or were other Claude Code users asking for something like this too?
haha this is the kind of small utility that actually makes sense. when a usage window matters, not knowing whether it’s active or about to end is just annoying for no reason. putting it in the menu bar feels like the right level of simple.
curious, are you planning to keep it super focused or add a bit more around usage tracking later?
Feels a bit niche to be honest .not sure how many users actively track the 2× window that closely.
