Weather Light vs Perun Weather

Weather Light is two apps in one: the weather where you are, and a flashlight. Tap the sun and the flashlight turns on. Drag a cloud over the sun and the light strobes. That is the trick people loved in 2013, and it is still here. THE WEATHER Weather from Apple Weather, the same data as the built-in Weather app: the temperature now, how it feels, the next 24 hours, the next 10 days, wind, humidity, pressure, UV, sunrise and sunset. Severe weather alerts from your local authority, when there are any. RAIN RADAR Where it is raining right now and where it will in the next two hours, as a loop over the map around you. WIDGET AND LOCK SCREEN A home screen widget with the temperature and the next hours, and, if you want it, the weather on the lock screen and in the Dynamic Island. THE FLASHLIGHT The camera flash, one tap away, in an app you open anyway. It turns off when you leave the app so it never drains the battery by accident. IN YOUR LANGUAGE 26 languages, Celsius or Fahrenheit, light or dark. FREE A small ad pays for the app. The one-time purchase from 2013 that removes it still works, and restores on any of your devices. Your location is used only to fetch the weather and is never stored on any server of the app. Weather data: Apple Weather. Radar: RainViewer.

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.
