Hindcast Weather

Hindcast is a weather app that tells you how sure the forecast is, not just what it says.

It blends seven forecast models (ECMWF, AIFS, GFS, HRRR, NBM, ICON and GEM), says how far they agree, and checks every forecast against the nearest weather station each night, so every place has a track record. Open it and you get one plain sentence, the temperature, and three tally marks for how far the models agree. Tap them for the reason in words. Everything else is one tap deeper, never all at once.

TODAY, AT A GLANCE
A headline, the temperature, the confidence marks, the next hours with their chance of rain, Today and Tonight, and a 10-day list. NWS alerts appear at the top with a link.

MODELS AND HIGHLIGHTS
Whether the models agree, mostly agree or are split on today, the range they put the high in and how many show rain. Highlights that state their evidence, and yesterday's high and low at the station against what was forecast.

RAIN IN THE NEXT 2 HOURS
Quarter-hour steps from 15-minute model data, shown when rain is due.

TRACK RECORD
The last 30 days of next-day forecasts against the nearest weather station: highs within 2°F, the average miss, rain calls right, the streak, a strip of receipts one per day, and the score at every lead from one day to seven. Free, wherever a station is within 25 km.

RADAR
In the United States, the radar loop every five minutes over a map of the place.

CONDITIONS
Air quality with fine particles against the WHO guideline, UV with its level, pollen in Europe, pressure and its trend, tides where there is sea, hours of sunshine, and the Moon.

HOUR, DAY, SKY, HORIZON AND CONTEXT
Tap any hour or day for its temperature and the range across models, rain, wind, UV, sun and the Moon. Cloud at three heights. Rain out to 40 km in any direction. Today against the typical high for the date.

PLACES
Search by name, save as many places as you like, see your current location. Times read in the place's own time zone and units follow your device's region.
