RainVis vs Perun Weather

RainVis turns detailed weather data into a visual forecast you can understand at a glance. Build your own forecast by choosing the details that matter most to you. Instead of jumping between separate hourly, daily, wind, rain, tide, and radar screens, RainVis lets you customize the forecast view around your plans. Track rain chance, accumulation, temperature, wind, gusts, humidity, pressure, dew point, cloud cover, tide height, tidal coefficient, and solunar timing in one visual forecast. Expand any day to inspect the hourly chart, compare multiple metrics together, and see when conditions line up. RainVis is especially useful for coastal fishing, boating, surfing, and outdoor planning, where the best window often depends on more than one number. Add tide and solunar details to your forecast to see tide movement, coefficient, moon timing, and major/minor activity periods alongside weather. Features: - Build-your-own forecast with customizable metrics - Compact daily forecast cards with visual hourly previews - Expandable hourly charts for rain, temperature, wind, gusts, humidity, pressure, dew point, cloud cover, tide, and solunar data - Coastal planning tools with tide height, tidal coefficient, NOAA tide source labels, moon data, and solunar activity periods - Rain-focused forecast showing chance, amount, timing, and accumulation - Current conditions for searched cities, saved places, or your current location - Radar with recent NEXRAD reflectivity history - iOS widgets for quick glanceable forecasts - Optional RainVis account for syncing Pro access across devices RainVis works immediately without signup. Free users can view the core visual forecast experience. RainVis Pro unlocks deeper planning features, including 15-day forecast trends, extended hourly forecast charts, longer radar history where available, live activities, and account-based access across iOS and web. Weather forecasts and coastal conditions can change quickly. Always follow official alerts and emergency guidance from the National Weather Service, NOAA, and local authorities.

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.

The app queries the public weather services directly; only the coordinates of the selected location are transmitted.
