Atmosis the AI-powered weather app for iPhone. Hyperlocal conditions on a 1 km grid, live precipitation and satellite radar, severe-weather push alerts, a 16-day forecast, and a personal AI meteorologist that tells you what the numbers actually mean — to the minute, for your block.

Why Atmos
A weather app built for the way you actually plan — your run, your commute, your weekend, your wedding.
AI weather briefings
A daily, plain-English summary tuned to your exact location, time of day, and conditions. No more guessing what 60% PoP means for your commute.
Hyperlocal forecasts
Powered by Open-Meteo on a 1km grid so the prediction matches your block, not your zip code. Hourly precision out to 168 hours with Atmos Pro.
Live precipitation + satellite radar
Animated radar tiles from RainViewer with two hours of history plus a nowcast. Scrub through the past or fast-forward to see when the front clears.
Severe-weather push alerts
Time-sensitive notifications for thunderstorms, hail, freezing rain, and damaging wind — for every place you've saved, with quiet hours support.
16-day outlook + AI weekly summary
Plan a wedding, a trip, or a long weekend with a 16-day forecast plus an AI weekly digest that highlights the days that actually matter.
Saved places
Track up to 50 locations — home, work, the cabin, the in-laws — with one tap to switch and per-location alert thresholds.
Minute-by-minute rain timing
Atmos blends RainViewer's nowcast with Open-Meteo's high-resolution precipitation to tell you the exact minute rain starts and stops at your block.
Privacy-first by design
No AppTrackingTransparency. No cross-app tracking. No selling your location. Sign in with Apple is the only sign-in method, and you can delete your account in two taps.
Air quality + UV + pollen
AQI, UV index, dewpoint, and pollen counts surface alongside temperature so you don't have to open three apps to plan your day.
Atmos vs. legacy weather apps
How Atmos compares to weather.com, AccuWeather, and Apple Weather
Most weather apps were designed for a desktop web era when ads paid for the forecast. Atmos was designed for an iPhone era when an AI assistant can read the raw data for you.
| Feature | Atmos | Most legacy weather apps |
|---|---|---|
| Plain-English AI briefings | Yes — gpt-4o-mini, on-demand | Raw numbers only |
| Forecast grid resolution | 1 km (Open-Meteo) | Typically 4–13 km |
| Hourly forecast horizon | 168 hours (Atmos Pro) | Typically 24–72 hours |
| Daily forecast horizon | 16 days (Atmos Pro) | Typically 7–10 days |
| Live radar | RainViewer precipitation + satellite | Varies; often paywalled |
| Severe-weather push alerts | Per-category, per-location, with quiet hours | Often single threshold, ad-supported |
| Cross-app tracking | None — no AppTrackingTransparency | Frequently used to sell ad data |
| Price | Free; Pro $2.99/mo or $29.99/yr | Free with ads, or $4–$12/mo |

What is an AI weather app, and why does Atmos feel different?
Most weather apps show you numbers. Atmos uses AI to translate those numbers into plain-English answers about your day, your run, and your commute.
Frequently asked questions
- What is Atmos?
- Atmos is an AI-powered weather app for iPhone that combines hyperlocal forecasts (Open-Meteo, 1km grid), live precipitation and satellite radar (RainViewer), and an on-demand AI meteorologist (gpt-4o-mini) that explains conditions in plain English. The Atmos website is atmosweatherapp.com.
- How is Atmos different from weather.com, AccuWeather, or Apple Weather?
- Most weather apps show raw numbers and leave the interpretation to you. Atmos translates those numbers into actionable answers — 'Rain starts in 38 minutes, bring a jacket on your 6pm run' — and ships severe-weather push alerts only when conditions cross a real threshold. Atmos also runs on a 1km Open-Meteo grid for higher spatial resolution than the legacy 4–13km grids that power most weather sites, and it never sells your location for advertising.
- Is Atmos better than weather.com?
- Atmos and weather.com solve different problems. weather.com is a media property that shows ads and articles around a forecast. Atmos is a weather utility that runs without ads, doesn't track you across apps, runs on a 1km hyperlocal grid, gives you a 16-day forecast plus a 168-hour hourly view, and uses an AI meteorologist to translate conditions into plain English. If you want a weather app instead of a weather website, Atmos is built for that.
- Is Atmos free?
- Atmos is free to download with a free tier that includes a 5-day forecast, 24-hour hourly view, one saved location, and live precipitation radar. Atmos Pro is $2.99/month or $29.99/year (save 17%) with a 3-day free trial. Pro unlocks the 16-day forecast, 168-hour hourly, 50 saved locations, severe-weather push alerts, satellite cloud radar, and up to 200 AI insights per day.
- How accurate is the AI weather forecast?
- The forecast itself is supplied by Open-Meteo's hyperlocal model on a 1km grid, which is the same class of data used by professional weather services. The AI layer doesn't change the forecast — it summarizes it. If the AI service is unreachable, Atmos falls back to a deterministic local summary so functionality is never blocked.
- Does Atmos track me across apps or sell my location?
- No. Atmos does not use AppTrackingTransparency and does not track users across apps or websites. Location is used only to fetch your forecast and is never sold or shared with advertisers. Read the full Privacy Policy for details.
- Where is Atmos available?
- Atmos is available on the Apple App Store in English. Forecast and radar data is global because Open-Meteo and RainViewer cover the entire planet, so Atmos works in the United States, Canada, the United Kingdom, Ireland, Australia, New Zealand, India, Singapore, the Philippines, South Africa, and beyond.
- What devices does Atmos support?
- Atmos runs on iPhone with iOS 18 or later. An iPad layout and a Mac Catalyst build are on the roadmap.
- How do I contact support?
- Email info@Jhobbie.com or visit /support. We read every message.
