Loved by developers
“I wanted a native, minimal menu bar app to monitor my Claude usage. Something not vibe-coded or overengineered. After trying several, I settled on this one. It's fast, simple, and does exactly what it should without unnecessary features. Definitely worth the purchase.”

“I was losing track of my Claude usage every single day. I'd be deep in a project, hit the rate limit, and just sit there waiting with no idea when it would reset. SessionWatcher changed that completely. Now I just glance at my menu bar and know exactly where I stand. It paid for itself the first time it saved me from a lockout.”
