Stop getting blindsided by Claude rate limits. ModelWitch puts your live Claude Pro usage right on your iPhone โ the same session, weekly, and Claude limits you'd otherwise have to dig for elsewhere. One glance tells you exactly how much runway you have left, with color-coded gauges that turn from green to orange to red as you approach your limit. CORE TRACKING โ FREE โข Secure Claude Pro login via real OAuth โ your password never touches the app โข Live 5-hour session usage gauge โข Live 7-day weekly usage gauge โข Live Fable 5 weekly usage gauge โข Extra pay-as-you-go credit gauge, for accounts with it enabled โข Anthropic API cost dashboard with real-time intra-day estimates to beat the official 24-hour reporting lag (Admin API key) โข Optional monthly budget gauge for precise API spending guardrails โข Color-coded urgency at a glance โ green, orange, red โข Instant cached data on launch, so it works even offline โข Manual pull-to-refresh, plus best-effort background refresh roughly every 15 minutes โข Smart error recovery with plain-language explanations and one-tap fixes โข Custom usage alerts โ threshold warnings, limit-reached, and reset reminders โข 7-day usage history chart Everything above is fully usable with no payment, no extra account creation beyond your existing Claude Pro login, and no ads. GO PREMIUM FOR MORE Five upgrades for people who live in Claude every day: Apple Watch Your usage on your wrist โ a full Watch app displaying live session counts and real-time API cost estimates, complete with complications for Modular, Infograph, Meridian, and other faces, plus a Smart Stack card and Siri & Shortcuts support. iPhone Widgets Home Screen widgets in small, medium, and large sizes (featuring the multi-account dashboard with live intra-day API cost projections), and Lock Screen widgets including circular, inline, rectangular, and Dual layouts โ with interactive tap-to-refresh right from the widget. Always-Fresh Background Sync A dedicated push notification pipeline keeps your widgets, complications, and app reliably current in the background โ beyond what iOS's best-effort scheduler alone can guarantee. Deep Usage Analytics 30-day historical charts instead of 7, plus insight cards for average usage, days spent over 80%, your peak usage day, and your weekly trend direction. Usage Matrix A 90-day calendar heatmap across Session, Weekly, Sonnet, Fable, and Anthropic API spend โ spot patterns across every metric you track at a glance instead of digging through history one day at a time. A free trial is available on Premium plans, so you can try the Watch app and widgets before committing. BUILT FOR HOW YOU ACTUALLY WORK ModelWitch was built by a Claude Pro user who got tired of finding out mid-task that a session limit had quietly run out. It shows the same session percentage, weekly percentage, and precise "resets in Xh" countdown you'd get by checking on a laptop โ without needing a laptop open. PRIVACY BY DESIGN ModelWitch authenticates with Anthropic using a secure OAuth browser flow. Your credentials are never seen or stored by this app โ only an access token is kept, encrypted in the iOS Keychain. Usage data is cached locally on your device for offline access and is never sold or shared with third parties. ModelWitch is an independent, third-party app and is not affiliated with, endorsed by, or sponsored by Anthropic. "Claude" is a trademark of Anthropic PBC. Whether you're deep in an agentic coding session or just keeping an eye on your weekly budget, ModelWitch keeps your Claude Pro limits exactly where you need them โ at a glance, on your iPhone and your wrist.
