Liftoff: Rocket Launch Alerts

Live SpaceX telemetry during active webcasts — altitude, velocity, flight phase. Free, no ads, no subscription. Alerts at T-24h, T-1h, T-15m for the pads you follow.

Watch SpaceX climb in real time. Liftoff is the only launch app streaming live telemetry — altitude, velocity, flight phase — straight from active webcasts. Plus countdowns for every rocket launch worldwide and home screen widgets. Free, no ads, no subscription.

Every Falcon 9, every Starship, every Electron, every Atlas, every Ariane — one feed, sorted by what's next. Set a filter for the pads you actually care about and Liftoff will wake you up before T-0. Skip the YouTube rabbit hole. Skip the Twitter scroll. Open Liftoff and the next launch is right there.

LIVE TELEMETRY When SpaceX is on the pad, Liftoff pulls altitude, velocity, and flight phase out of the active webcast and renders it as a clean ribbon at the top of the launch screen. Watch the numbers climb through max-Q. Watch stage separation. Watch the booster decelerate on entry burn. No other launch app does this.

NEVER MISS A LAUNCH Push notifications fire at T-24h, T-1h, and T-15m — and only for the pads you've followed. Set Liftoff to alert you for Boca Chica and Vandenberg and ignore the rest, or follow every pad worldwide and get the full schedule.

HOME SCREEN WIDGETS Two responsive widget types across compact and wide sizes. Pin the next launch to your home screen with a final-hour countdown that ticks on the launcher. Choose a single-launch focus widget or a multi-launch upcoming feed.

THE FULL SCHEDULE Every upcoming rocket launch, worldwide: • SpaceX — Falcon 9, Falcon Heavy, Starship • NASA — Artemis, SLS, crew missions • Rocket Lab — Electron, Neutron • Blue Origin — New Shepard, New Glenn • ULA — Atlas V, Vulcan • ISRO, ESA, JAXA, Roscosmos, CNSA • Ariane 6, H3, Long March, Soyuz, and everything else on the manifest

LAUNCH DETAILS Tap any launch for the full briefing: mission overview, rocket specs, crew bios (when applicable), pad location with map, payload details, and a direct link to the official livestream.

OFFLINE-FIRST Launch data caches locally the moment you open the app. Lose signal at the viewing site? The countdown keeps running, mission details stay readable, and the schedule is still there.

DATA SOURCE Liftoff pulls from Launch Library 2, the most comprehensive open rocket launch database — the same source serious launch trackers have trusted for years. Schedules update continuously as agencies confirm, scrub, and re-target.

Built for people who set alarms for Starlink launches.
