AI Usage for Claude & Codex

When can I use my AI again? AI Usage answers in one sentence.

AI Usage tracks your Claude, ChatGPT Codex and Antigravity limits in one place. See how much of each limit is left and whether you will run out before the reset, and keep what is left and when it resets right on your home screen.

ONE-SENTENCE ANSWER
The top line tells you right away: everything is available, or which service frees up next and in how long.

SUPPORTED SERVICES

Claude (Pro, Max, Team)
• 5-hour session limit: how much is left and when it resets
• Weekly limit, plus the separate weekly Opus or Sonnet limit when your plan has one
• If you sign in to Claude Code with your Claude plan, it draws on the same limits, so you can check that usage here too
• Personal and team accounts side by side

ChatGPT Codex (Plus, Pro)
• Codex 5-hour limit and weekly limit
• When you sign in to Codex with ChatGPT, the app, CLI and IDE extension share the same limits
• Reset credits shown when your account has them

Antigravity
• Limits for each model group inside Antigravity (Gemini models, Claude and other models) with reset times

REMAINING OR USED, YOUR CHOICE
Bars show what you have left by default, or switch to what you have used. Every usage limit gets a countdown to its reset time.

WILL YOU RUN OUT?
A tick on each bar marks an even pace, and a forecast tells you whether you will hit the limit before the reset at your current pace. Tap a service for a 24-hour, 7-day or 30-day usage history chart.

WIDGETS
Bar and ring widgets for the home screen. The large widget shows up to four AIs or accounts, and a small widget can show the AI you pick.

ALERTS
Get one heads-up when a limit drops to your level (20% by default), and a reset reminder when a limit you hit is expected to refill.

PRIVATE BY DESIGN
No sign-up. Your logins and usage history stay on your phone, and your logins are sent only to the AI service itself. Apart from a routine update check, the app sends us nothing about you. No ads, no analytics, no tracking.
