Features
Everything you need, nothing you don't.
A focused utility that answers one question well — how much Claude Code usage do I have left — and stays out of the way the rest of the time.
Tray / menu bar
Keep the app out of the way until you actually need it — a click away in the system tray or menu bar.
Prompt Calculator
Estimate whether a task is likely to fit within your remaining usage — as a range, with a confidence level.
Lightweight
Designed to stay idle and consume minimal resources — built on a native WebView, not a bundled browser.
Privacy-focused
Keeps the experience local and avoids unnecessary data collection. No account, no tracking.
Cross-platform
Available for Windows and macOS, with native conventions on each — one focused tool, two platforms.
Prompt Calculator
Will your task fit?
Before you start a big task, the Prompt Calculator estimates how likely it is to finish before you run out of usage. It weighs a few signals and returns an honest range — never a fake exact number.

Latest release Installers come straight from GitHub Releases. Requires Claude Code installed and signed in on the same device.
Builds are currently unsigned, so Windows SmartScreen or macOS Gatekeeper may prompt on first launch. See the install notes.
Privacy
No account. No tracking. No unnecessary data collection.
The app reads your existing Claude Code session locally and only makes the same usage request Claude Code itself makes — with your own local token, when you ask it to. Your prompts stay on your machine.
Reads your local session read-only — it never creates its own credential store.
The Prompt Calculator runs entirely on your device.
