Your View provides location-based viewing context for U.S. App Store users when data is available. On iPhone, enable free T-10 reminders for eligible countdown-ready launches when notifications are enabled. BUILT TO KEEP UP WITH LAUNCH DAY Launch plans change.

MAKE LAUNCH DAY YOURS WITH PREMIUM Premium brings your launch day into focus: • Your AR launch guide: AR Pad points toward the launch area for eligible missions. • Deeper viewing insight: explore more weather and viewing interpretation when available. • Alerts your way: follow missions, providers, rockets, pads, or launch sites. Customize reminders, supported timing and status alerts, and quiet hours. • Countdown at a glance: keep eligible countdowns close with Live Activities and Dynamic Island, and add Home Screen and Lock Screen widgets on supported iPhones. • Make it yours: color the app with a solid color, a gradient, Spectrum, or your own hue, from Soft to Neon. Widgets and the Live Countdown follow; launch status colors never change. • More ways to plan: review launch changes since your last visit, and use calendar and feed tools. ON IPHONE DUO Keep the countdown on the cover display, then open iPhone Duo to spread Today and launch details across the inner display. ON APPLE WATCH Check your selected launch, follow its countdown, see available viewing outlook, and add launch complications to your watch face. Setup requires a paired iPhone. Viewing outlooks are available for U.S. App Store users. Some features require Premium. Launch schedules, weather, viewing guidance, and notifications are planning aids and can change. Viewing tools and alerts vary by mission, device, and settings. Notifications are delivered on a best-effort basis. T-Minus Zero is independent and is not affiliated with or endorsed by launch providers, agencies, or data sources. Premium subscriptions renew automatically unless canceled at least 24 hours before the end of the current billing period. Available plans, offers, and prices are shown before purchase and may vary by region. Manage or cancel subscriptions in App Store settings.
