Know your AI limit
before it breaks your flow.
RunDog turns your remaining Claude and Codex quota into a tiny runner in the Mac menu bar: free, private, and always visible.
macOS 14 or later · Apple Silicon and Intel
Less quota. Faster runner.
It strolls when you have plenty, speeds up as quota runs low, and sleeps until reset when you hit the limit. You can read the situation without opening a dashboard.
Your notch becomes a battery gauge
Battery level glows along the edge of the MacBook notch. A light flows while charging, and you can pick standard, custom, rainbow or random colors. Hidden automatically on Macs without a notch.
Updates automatically, refreshes on demand
Usage refreshes every 60 seconds, or instantly with Refresh. Switch accounts from the account menu, and new versions install in place.
A runner for status and personality
Pick from eight runners and watch it react to what you have left: an easy stroll while usage is plentiful, faster in stages as it runs low, and asleep when you hit the limit.
Make it yours in the menu bar
Toggle the Claude and Codex runners separately, then tint them with the rainbow, thirteen colors, a preset that follows your macOS accent color, or your own hex code. You can flip the running direction too.
System info at a glance
Check CPU, memory, storage, battery, and network status in the System tab of the RunDog Settings window. Turn on only the items you want to see.
Let it rest, or swap it every 10 minutes
Stop the runner to hold it still for a while, or turn on random runner changes and a different runner takes over every 10 minutes. Open at Login and runner visibility live in the RunDog Settings window.

Frequently asked questions
- What is RunDog?
- RunDog is a free macOS menu bar app that shows remaining Claude and OpenAI Codex (ChatGPT) subscription usage and reset times.
- Is RunDog the same app as RunCat?
- No. RunDog pays tribute to RunCat's menu bar runner concept, but it is an independent app built to monitor Claude and Codex usage.
- What is the notch battery ring?
- A light along the edge of the MacBook notch that shows battery level. It flows while charging, and you can pick standard, custom, rainbow or random colors. It turns on for MacBooks with a notch (MacBook Pro from 2021, MacBook Air from M2) and stays hidden on other Macs.
- Can I make my own runner?
- Yes. Open Create Runner at the bottom of the runner list and pick PNG frames (36px tall, 10 to 100px wide); your runner then runs in the menu bar. Keep the image colors or apply color presets and rainbow, its running speed is saved, and you remove runners from the same window.
- Which Macs can run RunDog?
- RunDog supports Apple Silicon and Intel Macs running macOS 14 or later.
