Liftoff: Rocket Launch Alerts

Liftoff is the rocket launch tracker and space launch schedule for people who actually follow launches. See every upcoming launch, pin a countdown to your home screen, 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 — one launch schedule, sorted by what's next. Free, no ads, no subscription, no account.

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. Alerts are deliberately tuned to stay calm: a launch sliding its time won't spam you with repeat pings, and on Android you control each notification channel — countdowns and schedule changes — separately.

WATCH IT LIVE
When a launch has an official webcast, the stream surfaces right at the top of the launch screen, and a STREAM badge marks it on the feed the moment it goes live. No more hunting across YouTube tabs for the right link.

LIVE SPACEX FLIGHT DATA — WHEN AVAILABLE
During select SpaceX webcasts, Liftoff reads altitude, velocity, and flight phase out of the active stream and renders them as a clean ribbon at the top of the launch screen. When the data is flowing, the numbers tick up in real time as the booster climbs through ascent, staging, and entry burn. Availability depends on the broadcast — when it's there, it's a view no other launch tracker gives you.

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 and booster specs, provider, crew bios when applicable, pad location with map, payload details, a count-up clock after liftoff, 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.

BUILT FOR EVERYONE
Liftoff is tuned for TalkBack and scalable text, with a dark, deep-space aesthetic that's easy on the eyes during a 4 a.m. launch window. Got a request or hit a snag? There's a feedback channel built right into the app.

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, no account required. Built for people who set alarms for Starlink launches.

Recent changes:
Live launches stay live — no more flipping back to "window closed" mid-flight. Fixed schedule-update notifications not turning on for new installs. New themed icon, and the launcher icon is sharp again on high-density screens.
