Liftoff: Rocket Launch Alerts

Liftoff is a free rocket launch tracker that provides a comprehensive feed of all upcoming rocket launches worldwide. This includes launches from major space agencies such as SpaceX, NASA, Rocket Lab, Blue Origin, ULA, ISRO, ESA, JAXA, Roscosmos, and CNSA, as well as other launch providers like Ariane 6, H3, Long March, and Soyuz. With Liftoff, users can stay updated on the entire global launch schedule in one place.

One of the key features of Liftoff is its push notifications and launch alerts. Users can receive countdown alerts at T-24h, T-1h, and T-15m before every launch they have followed. This includes updates on scrubs, delays, and re-targets, ensuring that users are always informed about any changes to the launch schedule. These alerts are designed to be non-intrusive and can be customized on Android devices.

For launches with official webcasts, Liftoff provides a direct link to the live stream at the top of the launch screen. This eliminates the need for users to search for the correct link on different platforms. Additionally, during select SpaceX webcasts, Liftoff displays live flight data such as altitude, velocity, and flight phase in real-time, providing a unique viewing experience for users.

Users can also filter the launch schedule based on their preferences. They can choose to follow only specific launch pads or track all launches worldwide. This feature also applies to push notifications, ensuring that users only receive alerts for launches they are interested in.

Liftoff also offers home screen widgets that display countdown timers for upcoming launches. These widgets come in two sizes and can be pinned to the home screen for easy access. Users can also access detailed information about each launch, including mission overview, rocket and booster specifications, crew bios, pad location, payload details, and a direct link to the official livestream.

One of the unique features of Liftoff is its offline-first approach. The app caches the full launch schedule locally, allowing users to access it even without an internet connection. This is particularly useful for users who may lose signal at the viewing site.

Liftoff is designed to be accessible for everyone, with features such as TalkBack and scalable text. It also has a dark, deep-space aesthetic that is easy on the eyes during early morning launches. Users can also provide feedback directly through the app.

The data for Liftoff is sourced from Launch Library 2, a comprehensive open rocket launch database that has been trusted by serious spaceflight trackers for years. The app is completely free to use, with no ads, subscriptions, in-app purchases, or account required. It is built for space enthusiasts who want to stay updated on the latest rocket launches, including Starlink launches.
