AI Usage for Claude & Codex

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

Look for the FireUsage logo — that's us.

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.

Glance view
Every limit on one screen, with no scrolling. While it is open, the screen stays on and refreshes every 3 minutes. Great propped up on your desk.

Choose what you see
Pick which limits each card shows, and set the main limit used for the big number, widgets and alerts.

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

Used or remaining, your choice
Bars show what you have used by default, or switch to what you have left. Every usage limit gets a countdown to its reset time.

Will you run out?
The ▲ marker under each bar shows 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. Widgets follow your device's light or dark appearance. Bars are segmented, and bars and rings carry the same ▲ pace marker. The large widget shows up to four AIs or accounts and can list every limit of each card, 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.

Notification shade & quick settings
An optional ongoing notification and a Quick Settings tile show what is left at a glance.

Keeps up with each service
Shows every limit group the service itself shows, including Antigravity's Gemini 4 Argon. Rename any limit, get one note when a new limit appears, and see your reset credits. When a service changes how it reports usage, the app follows along without waiting for an update.

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 routine checks for app updates and service settings and a note when it meets a new usage-item layout (no numbers or account details), the app sends us no information about you. No ads, no analytics, no tracking.
