Everything about resets, in one radar
Built for developers who live inside Codex — spend your quota wisely and plan around every reset window.
Instant notifications
Get a local push the moment a regular or banked reset is announced — no polling, no missed windows, no battery drain.
Widgets everywhere
Lock Screen rings, Home Screen tiles and StandBy cards keep the countdown one glance away — no need to open the app.
26-week heatmap
A GitHub-style activity heatmap plus searchable history reveals reset cadence — spot patterns and plan heavy work around them.
Time-zone aware
Read every timestamp in UTC or your local time zone, with a tap-through breakdown — never guess when "2:30 PM" really lands.
Privacy-first
No account, no tracking, no analytics. Data is cached locally on your device and pulled from the public codex-resets.com project.

Glance & plan
Add a Lock Screen widget, check the heatmap for cadence, and schedule your heaviest Codex sessions right after each reset.
