StormNet is completely free, with no ads. Trained on decades of severe weather events, StormNet analyzes high-resolution radar, satellites, ground-based sensors, and weather forecast models in real-time to find complex patterns that lead to severe weather. The model updates every 2 minutes to provide 14-day forecasts for lightning, hail, damaging thunderstorm winds, and tornadoes. Super-Res Radar is the highest-resolution NEXRAD radar data available from 159 stations across the continental United States. Each radar station updates every 3-4 minutes and measures the intensity of precipitation based on how much energy the radar signal receives back from objects in the atmosphere. Combined, StormNet + Super-Res Radar provides a first-of-its-kind, multiple-component severe weather forecast system for the United States. StormNet Map Overlays • Radar: The highest-resolution radar available for the United States from each radar station. • Radar + Risk: NEXRAD radar, alongside StormNet risk probabilities, for the next 4 hours. • Risk Forecast: The StormNet risk probabilities from real-time to 14 days into the future. StormNet Risk Forecasts • Lightning • Hail • Damaging Winds • Tornado Super-Res (NEXRAD) Radar • Radar Reflectivity • Radar Velocity • Spectrum Width National Weather Service Warnings • Tornado • Severe Thunderstorm • Snow Squall • Flash Flood StormNet vs. National Weather Service The National Weather Service, the Storm Prediction Center, and other government agencies are the official sources for watches, warnings, and severe weather information. StormNet should serve as a trusted and automated guide for severe weather risk, but StormNet should not be treated as an official source. StormNet vs. Traditional Weather Models Existing weather forecast models are incredible feats of engineering and predict the ingredients for severe weather, but they are not designed to excel at severe weather forecasting and are not real-time tools. StormNet was trained and optimized to provide severe weather forecasts. StormNet vs. Other Weather Apps Existing weather apps and companies usually pass along official government watches and warnings, and often communicate if lightning or hail is already close by. While these are valuable features, we are not aware of another weather app or company that matches StormNet’s ability to provide real-time updates for lightning, hail, damaging thunderstorm winds, and tornado risk. Powered by OpenSnow In 2011, OpenSnow began predicting snowfall for skiers and snowboarders. OpenSnow has since become a global leader in mountain weather forecasts and expanded to provide forecasts for every type of outdoor activity. Since lightning is a risk to outdoor activities, especially on longer mountain-based adventures, OpenSnow created a weather forecast system that would provide both lightning forecasts to support real-time decisions and multi-day outlooks to support trip planning. Meteorologist Andrew Brady built StormNet to predict the risk of severe weather. OpenSnow acquired his technology in 2024 to help people stay safe and enjoy the outdoors. — Terms & Conditions — StormNet is free and available in the United States.

Hope y’all can update it more and make it even better than it already is! -Ethan -- ReallyEthan, 2026-04-18 ### ***** "Overall nice simple weather app" The app is very simple and user friendly which is great. There are plenty of features that can be added in future updates but one key improvement would be adding radar opacity controls and county overlays to make the app more visually appealing. -- Jackweather, 2026-03-26 ### ***** "StormNet" This is a game changer. One of a kind app!! Absolutely awesome!!!! -- SAP0570, 2026-03-14 ### ***** "Best Radar & Lightning App" Quick setup and easy to use. Love that the radar auto-selects to the location of where you are on the screen. No other weather app does lightning risk and strike data well and I think this app solves it. Great work. -- boulderguy1234, 2026-03-13 ### ***** "Severe Weather Forecasts" My new go-to source for radar and knowing if severe weather is heading for my area. I already love OpenSnow for mountain and daily weather, so it’s awesome to see them expanding into new verticals. -- MtnUnicorn, 2026-03-13 ### ***** "Best Severe Weather Tracking App!" This app is amazing! Being able to see severe weather risk zones a week out used to be unheard of. Great work! -- Waveslider80, 2026-03-13 [View all StormNet reviews and detailed analytics on AppTail](https://app.apptail.io/signup?utm_campaign=ai-crawl&utm_content=reviews) ## StormNet Available In - [United States](https://apptail.io/app/stormnet-QiRy/united-states) - [Canada](https://apptail.io/app/stormnet-QiRy/canada) --- ## About AppTail [AppTail](https://apptail.io) is a mobile app intelligence platform providing app analytics, ASO (App Store Optimization) tools, keyword tracking, competitor analysis, revenue estimates, and review monitoring for iOS App Store apps.
