  The study of flaring astrophysical events in the multi-messenger approach
requires instantaneous follow-up observations to better understand the nature
of these events through complementary observational data. We present
Astro-COLIBRI as a platform that integrates specific tools in the real-time
multi-messenger ecosystem. The Astro-COLIBRI platform bundles and evaluates
alerts about transients from various channels. It further automates the
coordination of follow-up observations by providing and linking detailed
information through its comprehensible graphical user interface. We present the
functionalities with documented examples of Astro-COLIBRI usage through the
community since its public release in August 2021. We highlight the use cases
of Astro-COLIBRI for planning follow-up observations by professional and
amateur astronomers, as well as checking predictions from theoretical models.
