Frequency Asked Questions

What is the difference between the weather radar data and weather forecast?

Weather radars provide the past and current info about precipitation movement. This is the actual info based on the sky screening as is. Radars typically detect the medium and heavy precipitation with extreme accuracy, though they may sometimes have nuances with the detection of light rain or drizzle. Radar data also allows you to build the short-term (up to 90 mins) accurate precipitation trajectory. A weather forecast is an algorithm that makes predictions for the further long-term precipitation movement. The forecasts are based on the math formulas and may not always be accurate for the next hour.

Does RainViewer work well in any region? If no, then how can I check if it works in my region?

RainViewer collects and processes data from weather radars throughout 90+ countries. These radars are not our property, and hence we cannot influence their total number and quality of work. Not all areas are covered with the weather radars. To start working with RainViewer, please verify if the radar covers your region by going to Settings - Radar Overlay - Coverage. The gray spaces on the map layer display the areas that are not covered with the weather radars. Therefore, RainViewer cannot provide an accurate rain forecast for these areas, just the general one (24 hours/7 days). If the radars map covers your current location, then please verify that the radar in your area works fine today (Menu - Single Radar mode - tap the radar to get more info).

May I use the RainViewer without the Internet and/or GPS connection?

Yes, you can use RainViewer with the GPS off. But if you want to get the rain alerts right for your current location, you have to turn on your GPS. Please also note that the widget will not work properly if you don’t allow the use of your GPS or add one more favorite location.

Which maps does RainViewer use? May I use my own maps in RainViewer?

RainViewer uses the default system maps (e.g., Google Maps for Android system, Huawei Maps for AppGallery version, and Apple Maps for iOS AppStore version). Unfortunately, you cannot use other maps except the default ones for our app.

What’s the difference between the radar and satellite map layers?

The radar layer shows information about the rain droplets in the sky (precipitation map) from the ground, while the satellite layer displays information about the clouds from the geostationary orbit. The weather radar gives better resolution (up to 125 square meters per pixel) and can monitor the required area quite often (once per minute).

Usually RainViewer shows the accurate weather data for my location. But today the radar in my region works bad or is offline. Is this RainViewer’s fault?

Despite using the weather radars data, we don’t own these radars, hence we have no impact on their work. Considering this, we can only collect the data from the radars mentioned, not generate it. You can check out if a radar in your area works fine today via Menu - Single Radar mode (tap the radar to get more info). If you believe that our app shows the wrong information about the radar’s current state, then please write us an email providing the trusted source of information to be analyzed. Thank you.

I want to see the weather radars data only on my precipitation animation map, not in the forecast. Is it possible?

Yes. You may manage the animation option in the app settings (Settings - Radar history). It is possible to choose between displaying the radars data + forecast, radars data only, and forecast only.

The data in radar animation is late for 10-15 mins. How can I fix this?

The delay may be caused by the long data processing and (or) delivering period from some radars to our server. Weather radars are not our property, and hence we have no impact on the quality of their work. You can find the exact time of recent radar images in the Single Radar mode.

I receive notifications about the precipitation in my region but nothing happens. Why?

The radar in your region may be extremely sensitive, so you may receive alerts about drizzles that are too light to be felt indeed. The alert system may need some time for calibration. Please try to choose the different precipitation intensity to be displayed both in the map and notifications.

Can I manage the precipitation intensity notified about in alerts?

No, you cannot. But we’re working on such a possibility. It will be available in the next month.

Can I change the notifications sound? Can I choose a unique sound for each favorite location?

No, you cannot.

I want to add a location to favorites but I cannot find the address via the Map Search field. What should I do?

The search engine may not detect some locations. If so, then please add the location manually. To do it, long tap the required place on the map. This action will redirect you to the option of saving your favorite location.

I’m a Premium user but after the reinstall, I no longer see any of my premium features. How do I return my subscription privileges?

If your subscription hasn’t been reactivated automatically after the reinstall, then go to the Premium Features purchase screen: Settings - RainViewer Premium - Show all Premium Features, and then tap Restore Purchase at the bottom of this screen. If you have an Android device, just wait a little: RainViewer checks your purchases automatically when you visit this screen. If nothing happens, check if the main account of your device is the same with which you made a purchase previously. Please note that you cannot transfer purchases and subscriptions between the AppStore and Google Play.

I purchased RainViewer subscription before summer 2020, but now the app wants me to buy it again. Why?

No worries, your purchase is still active, we’ve even added some new complementary features. We released the brand new version of the app in summer 2020. It contains both the changed subscription plan and new features. The purchase banners relate only to the acquisition of new options. If you aren’t interested in the upgrade, then just either skip the banner or tap Skip. For more information, visit our website

I decided not to pay monthly subscription any more. How do I cancel the monthly subscription?
