Flyby

✦ Your front-row seat to space

Most space apps give you a countdown and a YouTube link. Flyby tells you exactly when a launch or satellite will be visible from where you are — and shows you where to look.

Know exactly when you'll see a launch.

Flyby computes exact T+ time windows for when a launch will be visible from your location — what direction to face, how high to look, and precisely when it enters your line of sight. Not a generic countdown. A personal one.

Notification: You'll see this launch — Artemis II lifts off in 15 min Notification: Artemis II has lifted off from Kennedy Space Center

Know where to look.

Open the AR tool and Flyby places a marker on the launch vehicle or satellite in your sky. Point your phone up and find it.

Only passes worth going outside for.

Flyby factors in orbital geometry, solar angle, atmospheric conditions, satellite brightness, and your local light pollution. You only get notified for passes you can actually see.

Notification: ISS in 5 minutes — step outside and face west
