ThatSat: Satellite Finder

A moving point of light in the night sky — which satellite is that? ThatSat answers it in seconds, right on your screen. No account, no ads, no tracking. SEE WHAT IS UP THERE NOW Lay your phone flat and the sky dome shows every object you can see with the naked eye right now, where it is and where it is heading. The brightest one is named at the top: direction, height, brightness, and how long it stays visible. IDENTIFY WHAT YOU SEE Tap where the light is and swipe the way it moves. ThatSat lists the objects that match, best first. Or hold the phone up towards the light: the aiming view names the object under the crosshair. Prefer not to gesture? Choose a direction and a height instead. MORE THAN SATELLITES Rocket bodies and large debris shine too, and they are in the catalogue — every tracked object in orbit, not just the active satellites. PLAN THE NIGHT Before dark, ThatSat shows when darkness begins and tonight's brightest passes. Every object has its details and its visible passes for the next 48 hours. MADE FOR THE DARK Always dark, with a red mode one tap away that keeps your eyes adapted to the night. PRIVATE BY DESIGN Your location is used on your phone only and never leaves it. Positions are computed on the device; the app works offline with the last catalogue it has.
