OmniCast Weather
Weather Forecasting Unfiltered
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
OmniCast Weather helps you understand the forecast instead of hiding uncertainty behind one number.
Most weather apps show a single blended forecast. OmniCast lets you compare several professional forecast models side by side, including models from NOAA, ECMWF, Environment Canada, DWD, and more. When the models agree, you can plan with more confidence. When they spread apart, OmniCast makes that uncertainty visible.
Key features:
- Compare multiple weather models on one clean chart
- View temperature, precipitation, wind, precipitation probability, and cloud cover
- See model agreement at a glance
- Check 7-day forecast cards with model ranges and daily details
- Use live radar on the map for current precipitation
- Get daily or weekly forecast report notifications, written in your choice of voice
- Add Home Screen and Lock Screen widgets for quick forecast confidence
- Set weather alerts for rain, severe weather, wind, temperature, and forecast uncertainty
- And NO ADS!
Daily and weekly forecast reports summarize what the models agree and disagree on, delivered as a notification in whichever voice you prefer — a straightforward meteorologist, a numbers-obsessed model nerd, a gardener focused on planting and frost risk, or a stylist deciding what to wear.
OmniCast Pro (auto-renewing monthly subscription, free trial for eligible subscribers) unlocks Smart Forecast — a location-specific blended forecast trained on recent historical model performance, with confidence intervals — plus the full set of report voices. Subscriptions are billed through your Apple ID and subject to Apple's standard Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
OmniCast is designed for people who want more context before making weather-sensitive plans: commuters, runners, hikers, sailors, parents, photographers, event planners, and anyone who has wondered why two forecasts disagree.
Forecasts are informational and may be inaccurate. For life safety decisions, always follow official weather warnings and local emergency guidance.
