Every launch. Live.

Countdowns, SpaceX telemetry, and seven home-screen widgets — for the people who schedule their evenings around T-minus.

Built for the people who watch launches live.

  • Push when it matters

    T-24h, T-1h, and T-0 alerts per launch — per provider, per pad, per mission.

Questions, answered.

When is Liftoff launching?

App Store and Play Store in 2026. This site will flip to download links on launch day.

SpaceX, Rocket Lab, ULA, Blue Origin, ISRO, CNSA, Arianespace, and most other active launch providers tracked by public launch APIs.

A Firebase push token for notifications and your filter preferences stored on-device. No account, no analytics SDK, no advertising identifiers.
