Is there an iPhone app to track Codex resets?

Yes. AI Limit is an iPhone app that tracks public Codex resets with history, widgets, and push alerts.

Does AI Limit show my remaining Codex usage?

No. It tracks public reset announcements only. Your private remaining usage is in ChatGPT Settings → Usage or Codex /status.

Is AI Limit affiliated with OpenAI?

No. AI Limit is an independent app and is not affiliated with, endorsed by, or sponsored by OpenAI.

Codex Usage & Reset Tracker App for iPhone

A small native iOS app for developers who live in Codex and want to know when resets happen.

AI Limit is an independent iPhone app that tracks public Codex reset announcements: the latest reset, time since reset, history, average interval, widgets, and push alerts. It does not connect to your OpenAI account, so it cannot show your private remaining usage — use Settings → Usage or /status for that.

What the app does

Radar — latest reset, time since reset, and a countdown when a reset is scheduled.
Reset history & stats — every tracked global and banked reset, total count, and average interval. Same data as the web history.
Notifications — alerts for regular, banked, and scheduled resets.
Widgets — Home Screen and Lock Screen widgets. See Codex widgets.
Local time — reset times shown in your time zone.

What it does not do

It does not read your ChatGPT or Codex account, your prompts, or your private remaining percentage. That is a deliberate privacy choice: no login, no OAuth, nothing to revoke. To check your own windows, follow how to check Codex usage.

Who it is for

Developers on Plus, Pro, or Work seats who hit the 5-hour or weekly wall and want to be told when a public reset lands, instead of polling a website. Requires iOS 17 or later.

App vs web tracker

The web pages (live status, usage tracker guide) show the same public data. The app adds push alerts, widgets, and Live Activities, which a browser tab cannot do.
