Subpoint: ISS Atlas

More than an ISS tracker: see what the crew is doing, in which module, and where it is happening. Now at a limited-time launch price.

Subpoint shows you where the International Space Station is right now, who is on board, and what the crew is doing today. Unlike other ISS trackers, it doesn't stop at the dot on the map.

Subpoint connects live orbital data with the daily story of the station: which experiments are running, in which module they live, and which astronauts are working on them. It's a tracker, a Crew companion, and a research atlas - in one beautifully made app.

CORE FEATURES

• Live ISS tracker - see the International Space Station overhead in real time, with precise orbit computation from current TLE data.

• Pass predictions - find out when the ISS is visible from your sky with the naked eye. Your location never leaves your device.

• Crew on board - full profile for every astronaut on the station: mission, agency, biography, time in space, spacewalks.

• Daily activity - what the crew did today, structured from the NASA Space Station Blog and linked to research experiments and the modules they live in.

• Experiment depth - every research experiment explained in plain English: what it studies, who runs it, in which module. Sourced from public NASA catalogs.

• 3D module viewer - explore the ISS from the inside, with real racks and hardware. Tap a module and see what is happening there right now: Kibo, Columbus, Destiny, Harmony, Tranquility and more.

• Expeditions - every crew rotation since the station's first expedition: patches, members, mission highlights, attached spacecraft. Over 70 expeditions accessible.

• Beautiful design - Subpoint is built for ISS enthusiasts who want a tracker that respects their attention. No ads, no tracking, no clutter.
