Every rocket launch worldwide, in one feed sorted by what's next. Liftoff wakes you up before T-0, pins a live countdown to your home screen, and drops you straight into the official stream when a launch goes live. Free, no ads, no account. Every Falcon 9, every Starship, every Electron, every Atlas, every Ariane — one schedule, sorted by what's coming. Follow the pads you actually care about and Liftoff alerts you before liftoff. Skip the YouTube rabbit hole. Skip the doomscroll. Open Liftoff and the next launch is right there. NEVER MISS A LAUNCH Push alerts fire at T-24h, T-1h, and T-15m — and only for the pads you've followed. Delays, scrubs, and re-targets push through too, so when a Starlink launch slips you find out before you've parked in front of the wrong stream. Alerts are tuned to stay quiet: a launch sliding its time won't bury you in repeat pings. WATCH IT LIVE When a launch has an official webcast, the stream surfaces right at the top of the launch screen — a STREAM badge marks it on the feed the moment it's live, so you never have to go hunting for the link. LIVE 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, you watch the numbers climb through ascent, staging, and entry burn. Availability depends on the broadcast — when it's there, it's a view no other launch app gives you. HOME SCREEN WIDGETS Two widget types across compact and wide sizes. Pin the next launch with a final-hour countdown that ticks on your home screen, and choose a single-launch focus widget or a multi-launch upcoming feed. On iOS, a Live Activity keeps the countdown on your Lock Screen as T-0 closes in. 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 and booster specs, provider, crew bios when applicable, pad location with map, payload details, the count-up clock after liftoff, 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. BUILT TO BE USED BY EVERYONE Fully tuned for VoiceOver and Dynamic Type, with a dark, deep-space aesthetic that's easy on the eyes at 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 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.
