SkyLaunch tells you exactly when to look up — and how good the view will be from right where you are. For every upcoming SpaceX launch, SkyLaunch calculates a personalized visibility score (0–10) based on your distance to the launch pad, the sun's angle at launch time, and the cloud cover and atmospheric visibility from a 16‑day forecast. Twilight launches score highest — that's when the rocket's exhaust plume catches sunlight against a dark sky and can be seen for hundreds of miles. FEATURES • Live T‑minus countdowns for every launch • A visibility score for your exact location, with a full breakdown • All four active US launch sites — Vandenberg, Cape Canaveral, Kennedy, and Starbase • Custom reminders — 1 hour, 30, 15, or 5 minutes before liftoff • Set a minimum visibility score so you're only notified when it's worth stepping outside • Choose which launch sites to follow • Add any launch to your calendar • A Live Activity puts a live countdown on your Lock Screen and Dynamic Island • A home‑screen widget shows the next launch at a glance • Private by design — no account, no ads, no tracking Set your location once and SkyLaunch does the rest. SkyLaunch is an independent app and is not affiliated with or endorsed by SpaceX.
