I kept opening a terminal to check my AI agent limits, so I put them on my phone

Hi PH, I'm David, a solo developer. I've spent about the last year building apps on my own, and most of my code now gets written with AI coding agents. The thing that kept breaking my focus was checking how much usage I had left and when it would reset, which meant switching over to a terminal.

TokenWatch Usage Monitor is what I built for that. It shows usage and reset times for your AI agents on one phone screen (Claude, Codex, Copilot, Cursor and others are supported). I leave my phone in a dock beside the monitor with it open.

What it does:

  • A notification when a limit resets

  • The gauge changes color when you're using it up faster than the time that has passed

  • Pixel monsters show up on the gauges. Tap to catch them, and there's a collection book and a ranking
