Storm vs Sky Weather Apps: Which Tracks Better?

Storm excels at live radar and severe weather alerts, making it the better pick for storm monitoring. Sky delivers reliable Met Office forecasts for everyday UK planning. Your choice depends on whether you need real-time radar or simple daily outlooks.
Storm, developed by Weather Underground (a subsidiary of The Weather Channel), is a radar-first weather monitoring app available on iOS and Android. It was built for people who want to see where precipitation is right now, not just a summary of what might happen later.
The app's core feature is its animated Doppler radar loop. You can watch rain and snow cells move across a map in near real-time, scrub backward to see the last few hours of radar history, and scroll forward through a short-range forecast projection. Overlays let you add wind vectors, temperature gradients, and dewpoint maps on top of the radar layer.
Storm is particularly popular with outdoor workers, gardeners, event planners, and weather enthusiasts who need more than a simple rain icon. Its free tier is fully functional; the premium plan adds ad-free use and extended radar history.
Sky's weather tools are built into the Sky app, which is available on iOS, Android, and pre-installed on Sky Q and Sky Glass TV boxes. The weather section is powered by Met Office data -- the UK's national meteorological service -- giving it a strong accuracy advantage for British and Irish locations.
The interface is designed for simplicity. The home screen shows a clean 7-day forecast with icon-based condition summaries and high and low temperatures. Tapping any day expands it into an hourly breakdown, with additional data points including wind speed and direction, humidity percentage, UV index, and chance of precipitation by hour.
Sky weather is not designed for storm enthusiasts or outdoor professionals who need radar granularity. It is optimized for the most common use case: quickly deciding what to wear and whether to carry an umbrella, with data you can trust for UK conditions.
This is where the two apps diverge most sharply. Storm is built around radar; Sky treats radar as optional detail.
Storm radar step by step:
Sky precipitation view: Sky does not offer an animated Doppler radar map. Instead, the app displays an hourly rain probability bar chart for your saved location. This tells you whether it is likely to rain at 3 p.m. versus 5 p.m. but gives you no spatial information about where precipitation is currently located or how fast it is moving.
For casual users, Sky's approach is perfectly adequate -- you care about timing, not radar cells. But if you need to decide whether a storm will pass north or south of your town, or whether you have 20 minutes or 2 hours before rain arrives, Storm's radar is the right tool and Sky simply cannot answer those questions.
For everyday planning -- commuting, outdoor sports, weekend trips -- Sky holds its own against Storm and may have the edge for most UK users.
Sky's Met Office data is highly calibrated for British microclimates, where conditions can vary significantly between coastal and inland locations just a few miles apart. The Met Office runs high-resolution regional models that capture these differences better than global weather models. In practice, this means Sky's 24-hour forecast is often more trustworthy for UK locations than Storm's equivalent, particularly in coastal areas or near hills.
Storm's home screen defaults to a radar view, which can feel like information overload if you simply want to know whether it will rain this afternoon. You need to navigate to the forecast tab to get a clean hourly breakdown. Once there, the data is detailed and useful: Storm shows precipitation probability, expected accumulation in millimetres or inches, wind speed and direction, humidity, and UV index in a scrollable hourly strip. But the extra navigation creates friction for casual users.
Sky's home screen, by contrast, shows a clean summary card with current conditions, today's high and low, and a row of daily icons for the week. Tapping any hour on the hourly rail surfaces wind and rain probability at a glance. There is minimal friction between opening the app and getting the answer you need.
If you check weather several times a day for routine planning, Sky's shorter path is noticeably faster. If you check weather once a day but need deep data when severe events approach, Storm's radar depth justifies the extra steps.
Both apps support push notifications for incoming weather, but their alert types and customization differ considerably.
Sky's alert palette is more limited: it covers rain probability and temperature extremes but does not distinguish between tornado warnings, flash flood watches, and thunderstorm warnings the way Storm does. For UK users in low-severe-weather zones, Sky's alerts are sufficient. For users in areas with active tornado or hurricane seasons, Storm's granular alert types are essential.
Both apps are free to download, but their premium structures and platform availability differ.

If you are already a Sky subscriber in the UK, Sky weather costs you nothing beyond what you already pay, which makes it an easy default. If you are outside the UK or want radar-level data, Storm's free tier covers most needs without a subscription.
The right choice depends on your location, how you use weather data, and whether you need storm-tracking capability or a reliable daily forecast tool.
For most UK households, Sky's weather feature is the right everyday tool. Its Met Office accuracy, clean layout, and zero additional cost make it practical for daily use. Storm earns its place as a companion app for the moments when severe weather is approaching and you need to know exactly where it is and how fast it is moving toward you.
Yes. Storm is free to download on iOS and Android. The free tier includes animated radar, hourly forecasts, and severe weather push alerts. A paid subscription (approximately $3.99 per month or $19.99 per year) removes ads, unlocks radar history playback beyond 24 hours, and enables higher-resolution radar tiles.
Sky's weather feature uses Met Office data, which is the UK's national meteorological service and is widely regarded as the most reliable source for British and Irish locations. For UK users, Sky's forecasts will typically be more locally accurate than Storm's Weather Underground data, which covers the UK but draws on a global model rather than a dedicated national service.
Yes. Storm uses Weather Underground's global network of personal weather stations and radar feeds, covering many countries including the UK, Canada, and much of Western Europe. However, live Doppler radar coverage is strongest in North America. In regions with sparse radar infrastructure, Storm falls back to numerical weather model data instead of live radar imagery.
No. You can download the Sky app and access its weather tab for free without a Sky subscription. However, TV-integrated weather overlays on Sky Q and Sky Glass displays require an active Sky subscription. The mobile weather forecast view is open to anyone who installs the app.
Storm is significantly more capable for tropical storm and hurricane monitoring. It offers animated radar overlays, tropical alert push notifications, and integrates National Hurricane Center advisories when storms are active. Sky's weather tools are oriented toward UK day-to-day conditions and do not include dedicated tropical storm tracking.
Absolutely, and many users do exactly this. A practical setup is to use Sky for a quick daily forecast check in the morning and switch to Storm when severe weather is approaching and you need to track its path. Both apps are free at the base level, so there is no additional cost to keeping both installed.
