CalDown – Focus. Clarity. Time Awareness. What is happening now? What comes next? How much time is left? CalDown turns Apple Calendar events into a focused timeline across iPhone, iPad, widgets and Apple Watch. Choose your calendars and see your day without the clutter. Designed for clarity, not complexity. A TIMELINE BUILT AROUND NOW • Follow your current event with a live countdown and progress bar • Keep all-day, upcoming and recently ended events in view • Look ahead by 3, 5 or 7 days • See gaps between events and timed reminders • Create and edit events with the familiar Apple Calendar editor • Hide one event occurrence without deleting or changing it in Apple Calendar • Restore hidden events from a list organized by day; past-day occurrences are cleared automatically APPLE REMINDERS — BETA, WITH PRO • Show dated tasks from selected reminder lists alongside your events • Keep overdue tasks in Today and future timed tasks in the timeline • Complete tasks on iPhone or iPad with a checkmark and a gentle fade • Review dated tasks completed today in Done Tasks • Open Apple Reminders to create, edit or reopen tasks Undated tasks are not shown. Reminders do not occupy time or change event countdowns, and are not included in widgets or complications. WIDGETS THAT MAKE TIME TANGIBLE • See your current or next timed event on the Home Screen or Lock Screen • Preview following events in compact, combined and large layouts • Use calendar colors, countdowns and progress indicators • Hide the highlighted event directly from supported widgets Widgets and complications use your selected Upcoming range. Updates are scheduled by the system and may be delayed. APPLE WATCH — WITH PRO • View calendar events already available on your Watch, even without your iPhone nearby • Follow the iPhone’s calendar selection or keep a separate Watch selection • Expand event and reminder details in the timeline • See compact gaps and overlap durations between events • Prioritize the soonest-ending current event in the Watch timeline and complications • Collapse All Day and Reminders, with your preference remembered • Choose circular, corner, inline and rectangular complications • Use Corner Countdown for remaining time alongside a progress bar Complete reminders through your paired iPhone: offline requests stay pending with an hourglass until the iPhone confirms the save. Both devices need reminder access and the same reminder account. Some accounts cannot identify tasks reliably across devices. NOTES AND CHECKLISTS • Keep notes and actionable steps with individual calendar events • Store checklist items as readable Markdown checkbox lines in event notes • Add notes or checklist items from Watch without replacing existing content Watch additions and checklist changes require the paired iPhone to save and confirm them. Your calendar account manages synchronization. REMAINING TIME COLORS Choose warning and urgent colors, optionally with a separate start color. Preview each calendar for contrast and adjust colors and thresholds on iPhone. Apply them to the timeline, widgets and Watch independently. Tinted displays use system colors. Visual cues only — no alerts. SIRI AND SHORTCUTS Ask about Current, Next or Today’s schedule. Hide an occurrence, restore the last hidden event, or open Today and Upcoming. Use the returned text in your own shortcuts. YOUR DATA, YOUR RULES • No CalDown account, ads, subscriptions or analytics • On-device calendar and reminder processing, with no external CalDown server • Hidden-event preferences sync only with the paired Apple Watch, not through iCloud or between multiple iPhones • Optional technical diagnostic reports that you review and choose to share START SIMPLE. UNLOCK MORE WITH PRO. Use one calendar at a time and basic widgets without Pro. A single one-time purchase unlocks multiple calendars, additional widget layouts, Apple Watch and Apple Reminders integration. Your time. Your focus. CalDown.

Stop getting blindsided by Claude rate limits. ModelWitch puts your live Claude Pro usage right on your iPhone — 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 — FREE • Secure Claude Pro login via real OAuth — your password never touches the app • Live 5-hour session usage gauge • Live 7-day weekly usage gauge • Live Fable 5 weekly usage gauge • Extra pay-as-you-go credit gauge, for accounts with it enabled • Anthropic API cost dashboard with real-time intra-day estimates to beat the official 24-hour reporting lag (Admin API key) • Optional monthly budget gauge for precise API spending guardrails • Color-coded urgency at a glance — green, orange, red • Instant cached data on launch, so it works even offline • Manual pull-to-refresh, plus best-effort background refresh roughly every 15 minutes • Smart error recovery with plain-language explanations and one-tap fixes • Custom usage alerts — threshold warnings, limit-reached, and reset reminders • 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 — 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 — 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 — 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 — 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 — 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 — 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 — at a glance, on your iPhone and your wrist.
