Direct connection
Sign in with your ChatGPT account. Your phone connects directly to OpenAI, without a B1DEV intermediary server. Sign-in credentials are encrypted on your device. The app does not retrieve conversations or coding content. No computer connection or Codex installation is needed.

Last sync time
The widget shows the last successful sync, including at its smallest size. If usage has not refreshed for an hour, the ongoing notification also shows the last sync time.

Public reset news
News comes from the independent website codex-reset.com. The latest credit grant time refers to its monitoring accounts, not a confirmed grant to your account. Your own credit balance is fetched separately from OpenAI.

Requirements
Free to use. Supports Android 8.0 and later, including Android 17. Requires a ChatGPT account with Codex access. Ordinary ChatGPT conversation limits are not shown. Android battery and background restrictions can delay checks and alerts.

Codex Usage is an independent app by B1DEV, not an official OpenAI app. OpenAI, ChatGPT and Codex are trademarks of their respective owners.
