Heavens-Above Pro

The Live Sky Chart application allows users to see what is currently in the sky above them or at a specific time. This includes precise predictions for passes of the International Space Station and other visible satellites, as well as passes for amateur radio satellites with uplink and downlink information. Users can also find the location of bright comets, such as NEOWISE, in the sky.

All calculations for predictions are done locally on the user's phone, so a data connection is only needed every few days. The app also provides details about the orbit of any selected satellite, including relevant data. In the pro version, users can see the position of all satellites at once and filter them down.

Users can also access detailed information about any satellite through the app, as provided by the Heavens-Above website. The timeline feature allows users to get a visual overview of passes and animate the position of satellites on the sky chart and ground track. In the pro version, the timeline also includes elevation and detailed brightness predictions for passes.

The app offers a night mode option with a red on black color scheme to preserve the user's night vision. The tracker feature allows users to easily find or identify any object in the sky by orienting their device towards it. Additionally, users can quickly add interesting passes to their calendar through calendar integration.

In the pro version, users have the ability to create satellite entries with their own TLEs. This version is also free of advertisements, but users can try the free version before purchasing the pro version. Overall, the Live Sky Chart app provides a comprehensive and user-friendly way to explore and track objects in the sky.
