Quota Board shows Claude and Codex usage for multiple accounts, each provider on its own tab and reorderable within it. It renders the limit windows each service actually returns instead of assuming every plan has the same pair. WHAT IT SHOWS • A tab for Claude and a tab for Codex, at the same level, each refreshed by pulling down • An optional automatic order that puts the account whose weekly limit resets soonest first • 5-hour, 7-day, 30-day, model-specific, and named additional windows when reported • Claude extra-usage spending and Codex reset-credit availability when reported • The age of every reading. A stale accumulating value is marked with ≥ because it is an honest lower bound, not a current fact • Unknown data as unknown — never silently converted to 0% • English and Korean • A built-in mixed-provider demo before signing in WHAT IT CANNOT DO • Send prompts, messages, or inference requests, or consume reset credits • Ask for, capture, or store a claude.ai or ChatGPT session cookie • Import credentials owned by Claude Code or Codex • Sync credentials or back them up to another device SIGNING IN Claude uses browser OAuth and asks only for profile information. Anthropic does not offer third-party client registration, so its page displays Claude Code; Quota Board explains that before opening it. Codex uses OpenAI's device-code flow. Device login may need to be enabled in ChatGPT Security or by a workspace administrator. OpenAI does not offer a usage-only Codex scope, so the credential itself is not read-only; Quota Board's shipped code has no inference or reset-consume route and reads usage only. Codex and ChatGPT Work share usage for the selected workspace. Tokens stay in the iOS Keychain. Every request uses an honest User-Agent beginning quota-board/. PRIVACY No analytics, no Quota Board account, and no servers of ours. The app talks directly to Anthropic or OpenAI. Removing an account deletes its local credential and attempts provider revocation. Quota Board is independent and is not made by, endorsed by, or affiliated with Anthropic or OpenAI. Claude, Anthropic, ChatGPT, Codex, and OpenAI are trademarks of their respective owners, used only to identify the services the app reads.
