Our Apps
Lightweight environmental forecast tools built on open weather data. No account or location permission required — just open and check.
UVI Today
uvi.today →UVI Today shows the current UV index for any location worldwide, along with an hourly forecast for the day ahead. The app resolves your location using server-side IP geolocation — no browser location prompt and no tracking.
UV index values are sourced from the Open-Meteo API, which derives its UV forecast from the Copernicus Atmosphere Monitoring Service (CAMS) operated by ECMWF. The five-level exposure scale (Low / Moderate / High / Very High / Extreme) follows the WHO classification.
Features
- ✓Real-time UV index for any location worldwide
- ✓Hourly UV forecast for the current day
- ✓Burn-time estimate for Fitzpatrick skin types I–VI
- ✓WHO-based exposure category (Low → Extreme)
- ✓Automatic location via IP geolocation — no browser prompts
- ✓No account required, no personal data stored
- ✓Mobile-friendly, no app install needed
Data sources
- UV index: Open-Meteo (open-source, commercial-use license)
- Atmospheric model: CAMS / ECMWF
- Geolocation: IP-based, server-side only
Pollen Today
pollen.today →Pollen Today provides daily and multi-day pollen forecasts for six major allergenic plant types. The app covers European locations within the CAMS pollen model domain and resolves your location automatically — no browser prompts, no sign-up.
Pollen concentration data comes from the Open-Meteo API, which processes Copernicus CAMS pollen forecast output (SILAM model). The Low / Moderate / High / Very High scale follows EAACI threshold guidelines per pollen type.
Features
- ✓Daily pollen forecast for 6 plant types: alder, birch, grass, mugwort, olive, ragweed
- ✓Multi-day forecast (several days ahead)
- ✓Low / Moderate / High / Very High scale per EAACI thresholds
- ✓Automatic location via IP geolocation — no browser prompts
- ✓Coverage: European locations (CAMS pollen model area)
- ✓No account required, no personal data stored
Data sources
- Pollen forecast: Open-Meteo (open-source, commercial-use license)
- Atmospheric model: CAMS / ECMWF (SILAM dispersion model)
- Geolocation: IP-based, server-side only
