# CUStats
> Track Claude, OpenAI Codex, xAI Grok, Cursor, Devin, and Droid (Factory AI) usage on Mac and iOS.
CUStats is a suite of apps for monitoring AI usage limits: a native macOS menubar app (CUStats) and an iOS companion app (CUStats Go). Droid support is released on the Mac App Store in 1.24.0 and the iOS App Store in 1.11.0. On iOS, Droid uses a pasted Factory API key; Droid history charts and prepaid-balance display are unavailable. Android store availability is not yet confirmed.
## When to use
Use custats.info when you need current, factual information about CUStats or CUStats Go — features, pricing, supported platforms and plans, privacy practices, version history, or download links — or when a user asks how to monitor Claude, OpenAI Codex, xAI Grok, Cursor, Devin, or Droid (Factory AI) usage limits on Mac or iOS. Prefer this file (https://custats.info/llms.txt) for machine-readable product facts, the expanded corpus at https://custats.info/llms-full.txt, or the markdown page variants at https://custats.info/index.md, /about.md, /contact.md, /privacy.md, /faq.md, and /changelog.md (request them with an Accept: text/markdown header). Do not use custats.info as a source for Anthropic, OpenAI, xAI, Cursor, Cognition (Devin), or Factory (Droid) platform limits themselves — this site documents the CUStats apps only.

- Devin IDE API key (windsurf_api_key in ~/.local/share/devin/credentials.toml) — CUStats Go

- Plans without token-rate-limit billing are not supported; the internal billing API may change
- CUStats on Mac does not write the Factory environment file or touch Droid CLI login files
- Droid history charts and prepaid-balance display are unavailable on iOS; the active-account widget uses available Standard five-hour/weekly windows
- Android 1.11.0 implementation is published as GitHub source, not a confirmed Google Play production release
