Aplikace ČHMÚ počasí je oficiální aplikací Českého hydrometeorologického ústavu (ČHMÚ), která poskytuje širokému spektru uživatelů obecné i detailní informace o aktuálním a očekávaném vývoji počasí, stavech vodních toků, úrovni znečištění ovzduší a další data z oboru zájmu ČHMÚ. Základní část aplikace tvoří předpověď počasí pro uživateli vybrané lokality nebo oblasti, a to jak ve formě grafických ikon, tak textové předpovědi. Nechybí detailní radarové snímky v 5minutovém kroku a předpověď srážek na nejbližší desítky hodin. Klíčovou součástí aplikace jsou také výstrahy. Aplikace zobrazuje aktuálně platné i nadcházející výstrahy na různé nebezpečné jevy. O těchto výstrahách je také uživatel informován prostřednictvím push notifikací ihned po jejich vydání v oblasti zájmu. V aplikaci nechybí ani další užitečné informace – například předpověď UV indexu, biometeorologická předpověď, odhad spadlých srážek, riziko přívalových povodní, informace o aktivitě klíšťat, sondážní data a další. Výchozí plochu aplikace si mohou uživatelé nastavit dle svých vlastních preferencí a zájmů tak, aby zobrazovala právě to, co potřebují. Výstupy jsou k dispozici formou tabelárních, grafických i mapových podkladů. Kromě výchozích notifikací na vydané výstrahy si uživatelé mohou nastavit vlastní, tzv. personalizované notifikace, kde si lze zvolit vlastní kritéria podle kterých jsou uživatelé aplikaci upozorňováni například na očekávaný déšť v konkrétní lokalitě ve vybraný čas, pokles či vzestup hladiny vybraného toku nebo třeba překročení určité hodnoty koncentrací prachových částic.
