CUStats Go - AI Usage Tracker

Know before you hit your Claude, Codex, Grok, Cursor, or Devin limit. CUStats Go's pace metric predicts your weekly usage at reset, so you can ease off before the cutoff — not after. Privacy-first by design: your usage data stays on your device, your account credentials are stored only in the iOS Keychain, and there are no ads and no behavioral tracking.

Track each provider's billing windows, monitor model-specific consumption, and stay informed with smart notifications and multi-account management. Grok uses the Weekly or Monthly window xAI reports; Cursor maps plan usage to the billing cycle and on-demand to Extra Usage when enabled; Devin covers both the app.devin.ai agent quota and the Devin IDE plan quota.

Key highlights:
- Home screen widgets in three sizes: small, medium, and large multi-account dashboard (widgets require iOS 17 or later).
- Widgets update automatically in the background — no need to open the app.
- Widgets omit usage windows a provider does not report instead of showing a misleading 0%.
- Multi-account widget shows all connected accounts (up to 5) with per-account usage, pace, and reset times.
- Real-time monitoring of Claude, Codex, Grok, Cursor, and Devin with live progress bars.
- Pace Metric predicts your weekly usage at reset time. Know before you hit the limit.
- Promotion awareness: see when 2× usage windows are active with visual indicators.
- 7-day trend charts with session-level detail, prediction lines, and weekly reset indicators.
- Unified live session view with hero header and inline cumulative and peak charts.
- Color-coded statuses (Good, Caution, Critical, At Limit) clarify when to pause usage.
- Pace status indicators: Healthy (under 90%), Risky (90-100%), Over (above 100%).
- Smart notifications for configurable thresholds, reset alerts, weekly unused-usage reminders, and service status changes — including when Claude or Codex recovers; iOS checks Claude thresholds in the background (Focus-friendly).
- Extra usage (overage) credit tracking for paid plans.
- Built-in multi-account flow with numbered credential how-tos and secure Keychain storage.
- Width-adaptive iPad navigation (side rail at 600pt+), plus iPhone portrait and landscape.
- Local-first privacy: no ads, no behavioral tracking, no cloud syncing. Your usage data stays on-device, and credentials are kept in the iOS Keychain.

Perfect for developers, researchers, and busy professionals who rely on Claude, Codex, Grok, Cursor, or Devin and need portable visibility.
