Liftoff is the rocket launch tracker and space launch schedule for people who actually follow launches. See every upcoming launch, set a countdown, and get push alerts for the pads you care about. Every Falcon 9 lifting Starlink, every NASA crew mission, every Rocket Lab Electron, every Ariane 6 — on one launch schedule, sorted by what's next.

LIVE SPACEX TELEMETRY
Liftoff is the only rocket launch app that streams live telemetry during active SpaceX webcasts. Altitude, velocity, and flight phase render in a clean ribbon at the top of the launch screen and tick up in real time as the booster climbs through max-Q, stages, and starts entry burn. Open Liftoff a few minutes before T-0 and watch the numbers move. No other launch tracker does this.

EVERY ROCKET LAUNCH WORLDWIDE
One feed for the entire global launch schedule:
• 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 the rest of the launch calendar

PUSH NOTIFICATIONS & LAUNCH ALERTS
Countdown alerts fire at T-24h, T-1h, and T-15m before every launch you've followed. Scrubs, delays, and re-targets push through too — so when SpaceX slips a Starlink launch by 90 minutes, you find out before you've planted yourself in front of the wrong stream. Never miss the next launch.

LOCATION FILTER
Follow only the pads you care about. Set Liftoff to track Boca Chica and Vandenberg only, or follow every pad worldwide and get the full rocket launch schedule. Notifications respect the filter — no alerts for launches you've muted.

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

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
The full launch schedule 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 spaceflight trackers have trusted for years. Schedules update continuously as agencies confirm, scrub, and re-target.

Liftoff is a free rocket launch tracker — no ads, no subscription, no in-app purchases. Built for people who set alarms for Starlink launches.
