Hi Product Hunt 👋 I'm a public-health physician, not a farmer — but I spent a year listening to people who decide, every morning, whether to spray, cut, sow or irrigate, and who told me the same thing: consumer forecasts don't answer their question, because the question depends on their thresholds. Agrihélie reads the sky for a field with YOUR thresholds. Every morning it gives the three priority risks of the next 48 hours — frost, wind for the sprayer, rain, heat — each justified by a figure and a time. Then it computes the windows to spray, cut, sow or irrigate from the limits you set: maximum wind, rain-free hours after a treatment, soil temperature. It keeps a water balance per field (FAO-56 ET0, effective rain, available water), degree-days and chill hours, disease indices, the THI heat-stress index for the herd, and the local climate — ERA5 normals and CMIP6 projections by twenty-year windows. Twelve screens, and a Methodology page that explains every indicator. Data: Open-Meteo (ECMWF, Météo-France, DWD, NOAA, ERA5, CMIP6) through a professional plan, with 16-day ensemble spread — so every figure shows its uncertainty and its source. What it is not: no yield forecast, no live radar, no data collection. Your fields, journal and settings stay on your phone; no account, no ads. Free trial, no sign-up, on 3 real locations of your choice (Paris as demo) → https://agrihelie.neocities.org/... Then €0.99 once — that single payment funds the data access. I'd love your feedback on the default thresholds, on the indicators you'd add for your crop, and on the mornings when the result differs from what you would have decided — tell me the place, the date and the decision, and I'll check. Growers, agronomists and weather people: your critiques are the most useful thing today. Thank you!
