What it does

01 · Features
01Rain, by agreement

Several forecast models side by side. You see how many of them expect rain, when it starts and roughly how much.

02Right now, from stations

Current readings from ČHMÚ stations around Prague — Kbely, Libuš, Ruzyně and more.

03Warnings

ČHMÚ warnings with level, time window and a short description.

04Radar

One full-screen radar with layers. Play it, or scrub through time.

05What’s ahead

48 hours by the hour, 14 days by the day, plus air quality, UV and pollen.

Built in Pražské ticho

02 · Screens

The app’s own visual system, “Pražské ticho” (Prague quiet): calm, dark by default, light when you want it. Desktop and mobile share one design.
