Model Usage is a real time dashboard for your AI coding tool usage. See how much of your five hour window and weekly quota you have used, watch your session tick up live, and get notified before you hit a limit. HOW IT WORKS A small client runs on your computer and reads the usage files that your AI coding tools already write locally. It forwards that usage to a server address you control. The apps pair with that server over a QR code or short pair code. No account, no email, no login. LIVE WHERE YOU ALREADY LOOK - Live Activity: a glanceable card with your current session and weekly usage, visible on the lock screen and Dynamic Island. - Home Screen widgets: compact and expanded sizes that show your session, weekly totals, and rate multipliers at a glance. - Lock Screen widgets: a tiny usage indicator right next to the clock. PAIRS WITH THE REST OF YOUR DEVICES Once you are paired on one device, the same setup flows to every companion app automatically. Send a snapshot to anyone in a conversation with the Model Usage messaging app. PRIVACY BY DESIGN No analytics. No tracking. No accounts. No advertising SDKs. Your usage data goes from your computer to a server you choose, and then to your own devices. Model Usage never sees it. FEATURES - AI coding tool usage tracking, side by side - Five hour session window and weekly window - Live Activity with Dynamic Island integration - Companion apps across every size of screen - Messaging app for sharing usage snapshots - Lock Screen and Home Screen widgets in all sizes - Live rate multiplier awareness. Rate changes are reflected in real time. - Open pair code or QR flow. No account required. - Dark mode throughout SETUP IN UNDER A MINUTE 1. Install the desktop client. 2. Copy the pair code. 3. Enter it in the app. That is it. The setup guide lives at modelusage.app/setup. Model Usage is built by a solo developer and does not collect, store, or share any personal data.

Less checking. More building. Codex Tracker brings your coding agents' usage, limit resets, predictions, and service status together in one place, with push alerts when something changes—so you can keep your attention on turning ideas into working software. ===Know what you have left=== Connect your Codex account to see how much of your 5-hour and weekly limits remains, when each one resets, and how many resets you have available. Link more Codex accounts and other AI services, including Claude, GitHub Copilot, Cursor, Grok, Kimi, MiniMax, Z.ai, DeepSeek, and OpenRouter, then swipe between them on the home screen. Your credentials stay on your device. ===Get back to building=== Get notified when a new reset is tracked. Pick up that unfinished feature, revisit a bug, or start your next experiment without repeatedly checking announcements. ===Never get cut off mid-task=== Usage reminders give you a heads-up before a limit resets, right when it does, and when you're about to run out. Choose the levels that matter for each account. ===Know when it's not you=== Follow the public status of every AI service you use. See which products an incident affects, with translated details and recent history, and get alerted for the services that match your accounts. ===Plan your next coding session=== Follow the latest reset predictions to plan your next stretch of focused development. Line up your tasks, prepare your prompts, and get ready for another round of building. ===Your workflow, your notifications=== Choose alerts for new resets, predictions, incidents, or any mix. Filter reset notifications by regular resets, banked resets, or both. Keep the updates that matter to you and leave the rest off. ===See the bigger picture=== Read reset announcements in your preferred language, with the original text one tap away. Explore the reset calendar and statistics, including total tracked resets, average reset intervals, and the longest wait. ===Codex Tracker Pro=== Track as many accounts as you link, see your usage history with a forecast for every limit, and add Home Screen and Lock Screen widgets that show resets and every account's usage at a glance. From your first prototype to your next release, let Codex Tracker keep you posted. Terms of use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
