## What is CUStats Go?

Know before you hit your Claude, Codex, Grok, or Cursor 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.

Key highlights:
- Home screen widgets in three sizes: small, medium, and large multi-account dashboard.
- 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, and Cursor 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, or Cursor and need portable visibility.

## Version history (last 5 releases)

What's new:
- Add Grok (xAI) accounts with Weekly or Monthly billing windows
- Add Cursor accounts with a cookie from cursor.com

### 1.6.1 — 2026-07-31

Know when Claude and Codex come back up.

What's new:
- Service status recovery alerts tell you when Claude or Codex is fully operational again, not just when it goes down
- Recovery alerts have their own notification per service, so they appear alongside the outage alert instead of replacing it

Fixes:
- A dropped status check no longer hides a service going down — you could previously sit through a whole outage in silence after one failed check
- A partial improvement (outage back to degraded) correctly stays quiet while the service is still impaired

### 1.6.0 — 2026-07-24

Smarter limit visibility and more reliable alerts.

What's new:
- Weekly unused-usage reminder shows how much plan quota may go unused before the weekly reset
- iOS now checks Claude usage thresholds in the background, so alerts can arrive even when the app is not open
- Live view now shows 7-day usage limits for every Claude model your account reports

Fixes:
- Fixed foreground notification delivery and stale enabled-state handling

### 1.5.2 — 2026-07-23

New in this version:

- Notifications settings — permission status, master switch, per-alert toggles, and send test notification
- Codex manual reset credits on the Live tab when OpenAI reports them
- Smoother usage charts and shared fetch plumbing across Live, Overview, and All Accounts
