Perun Weather

Perun answers not only what the weather will be, but how reliable that answer is right now. SEVERAL MODELS INSTEAD OF ONE OPINION Most apps present a single weather model as the truth. Perun compares many – and picks them by location: ECMWF, GFS and other global models worldwide, plus high-resolution regional models where you are, such as ICON-D2 in Germany, ICON-2I in Italy, AROME in France, MeteoSwiss ICON in the Alps, HRRR in the USA, HRDPS in Canada or JMA in Japan. Radar and weather stations join in wherever they exist. From this comparison one clear statement emerges – for example: "This evening it will most likely stay dry." THE RELIABILITY VALUE Every statement carries a value between 0 and 100 per cent. It reflects how strongly the sources agree, how consistent they are about timing, whether the radar backs the forecast, how fresh the model runs are and how far ahead the forecast reaches. Every part can be opened up in the app. When the sources contradict each other, Perun says so – instead of feigning certainty. RAIN RADAR WITH THE OFFICIAL NOWCAST Radar measurements and the official two-hour forecast of the German Weather Service, in five-minute steps, as an animation. Forecast frames are clearly marked as such. In Italy Perun shows the radar image of the Civil Protection Department, in Canada and the USA the last two hours of measurements. OFFICIAL WARNINGS Weather warnings from the German Weather Service, the US National Weather Service and Environment Canada, precise for the selected location – with period, description and guidance. Radar, nowcasts and warnings exist only where a weather service provides them openly: Germany, Austria, Scandinavia, Italy, the USA and Canada. Everywhere else, Perun still shows the full model comparison, clothing advice and all metrics – and asks the nearest weather station whether it is raining right now. WHAT TO WEAR From apparent temperature, precipitation, wind and UV index Perun derives a concrete suggestion: jacket, umbrella, sturdy shoes or sun protection. METRICS THAT EXPLAIN THEMSELVES Wind, humidity, pressure, UV index, visibility and cloud cover can be tapped. Each metric explains what it means, places the current value with everyday examples – and warns when it gets critical. ENERGY (OPTIONAL) If you want, Perun combines dynamic electricity prices with your tariff, your PV system and your battery. It calculates the real value of a kilowatt-hour – not the market price alone – and recommends when to buy, self-consume, store or feed in. Off by default; no electricity prices are requested unless you enable it. MORE • Freely sortable home screen • Widgets for home and lock screen • Notification before rain sets in • Save several locations • Last loaded data stays visible offline, always with a timestamp WITHOUT THE CLUTTER No account, no ads, no tracking, no server of our own. The app queries the public weather services directly; only the coordinates of the selected location are transmitted.
