Quick comparison

The feature and coverage details below come from each app’s store listing, not independent checks of radar accuracy. Prices are marked unknown when the available listing details don’t establish them.

1. RainViewer: Live Weather Radar

Best for: An all-around rain radar with stated worldwide coverage.

RainViewer: Live Weather Radar combines live precipitation maps with radar playback, short-term rain forecasts, and alerts. Its listing says it covers locations worldwide, which may be useful for travelers and people checking conditions near home.

Radar playback is a useful feature here. It shows how precipitation has moved, rather than just what the map looks like now. That can help you follow a rain band’s recent direction before heading out.

2. Rain Alarm Live Weather Radar

Best for: Alerts when rain or snow is approaching.

Rain Alarm Live Weather Radar displays animated radar images and sends alerts when precipitation is approaching. Its listing says it uses NOAA Doppler radar data in the United States. Coverage and data sources may differ in other regions.

The main appeal is the approaching-rain and snow alerts. They can let you know when precipitation is moving toward your area, so you don’t have to keep checking the radar map.

3. Rain Radar: Weather & Cyclones

Best for: Local precipitation views alongside cyclone tracking.

Rain Radar: Weather & Cyclones shows moving rain and snow maps, radar playback, and a location-based view of nearby or expected precipitation. It also includes cyclone paths, combining local rain checks with tropical-system tracking.

Cyclone paths set this app apart. They may be useful if you follow tropical systems as well as everyday showers. Playback also lets you review how precipitation has been moving.

4. RainDrop - Rain Totals & Radar

Best for: Checking precipitation totals alongside radar.

RainDrop - Rain Totals & Radar combines precipitation totals with forecasts, alerts, and animated rain and snow radar layers. Its listing describes coverage across the United States, so check that your area is included before relying on its local view.

The totals help you compare how much precipitation has fallen, not just where rain is on the map. RainDrop may suit you if accumulation matters as much as what’s coming next.

5. Storm Radar: Weather Tracker

Best for: Tracking storms with multiple weather layers.

Storm Radar: Weather Tracker offers a live radar map with precipitation, lightning, wind, and tropical-system layers. Its listing also mentions rain alerts and future-radar views, putting several storm-tracking tools in one app.

The mix of future radar and storm layers is its main draw. You can check conditions beyond basic rainfall, then use the future view to plan around expected weather.

6. Weather Radar: Tornado & Storm

Best for: Android users who want rain maps with severe-weather tracking.

Weather Radar: Tornado & Storm offers live weather radar and storm tracking, with rain, wind, and cloud-cover layers, according to its Google Play listing. It also includes tornado alerts for people monitoring severe weather.

Tornado alerts distinguish this app from the other picks. They can provide another way to keep watch, but app alerts should not replace official warnings or local emergency guidance.

How we picked these apps

This roundup covers mobile apps with rain radar or precipitation maps and tools for checking changing conditions. We compared features such as radar playback, forecasts, alerts, precipitation totals, and additional storm layers.

Platform availability and stated coverage are also worth checking: five apps are listed for iOS and one for Android. Store listings describe features and coverage, but don’t confirm that radar data, forecasts, or alerts work equally well everywhere. Check the listing for details relevant to your area.

Frequently asked questions

What does a rain radar app show?

A radar map shows precipitation in an area. Some apps animate the map so you can see how it has moved. Forecasts estimate future conditions, while alerts notify you about specified weather. These features are related, but they aren’t the same.

Do rain radar apps work everywhere?

Coverage varies by app and location. Check the store listing to see which areas it says it covers, and confirm that your location is included before relying on its maps or alerts.

Can I rely on radar alerts?

Radar-based alerts and future-radar views can help with planning, but they shouldn’t replace official warnings. Check current store listings for platform availability and feature details, and follow local authorities’ guidance during severe weather.

The verdict

The apps in this roundup offer different combinations of radar, playback, forecasts, alerts, and storm layers. RainViewer combines several of those features with stated worldwide coverage. Rain Alarm focuses on approaching-rain and snow alerts, while Storm Radar includes lightning, wind, tropical-system layers, and future radar. Check coverage for your location and choose the features that matter most to you.
