Chirp is an app that allows you to keep track of the latest collisions of black holes, neutron stars and maybe more, just minutes after they are detected by the growing international gravitational wave detector network – LIGO (Laser Interferometer Gravtiational Wave Interferometer) in USA, Virgo in Italy, and KAGRA in Japan online from Feb 2020.

Chirp is available for Android, iOS and web and can be downloaded for free here. It contains no ads and no in app purchases. If you prefer to use a webpage instead of a mobile app, or just want to see what this is all about, have a look at:
