Rain Viewer App
The Weather Radar App That Finally Gets British Rain Right
Most weather apps on the iPhone do the job for a quick temperature check or a rough idea if it might rain later. But when you need to know whether that grey sky is about to soak you on your way to the shops or during a dog walk, they often let you down.
Rain Viewer is different. I have been using it on my iPhone for a while now and it has become the one I actually trust when the weather looks dodgy.
What I like most is how it uses real raw Doppler radar data instead of the smoothed out versions you get elsewhere. The map feels sharp and detailed. You can tap anywhere and see exact precipitation strength, cloud temperatures, surface temps and little arrows showing exactly which way the rain is moving. Updates come every five minutes in most places and the two hour nowcast has saved me more than once.
Standout Features That Make Daily Life Easier
What I like most is how it uses real raw Doppler radar data instead of the smoothed out versions you get elsewhere. The map feels sharp and detailed. You can tap anywhere and see exact precipitation strength, cloud temperatures, surface temps and little arrows showing exactly which way the rain is moving. Updates come every five minutes in most places and the two hour nowcast has saved me more than once.
The map runs really smoothly at 60 frames per second thanks to the GPU stuff they use. It works brilliantly with Live Activities too. There is a little graph on my lock screen that shows the rain intensity minute by minute with a countdown so I know whether to grab my coat now or wait ten minutes.
The standalone Apple Watch app is handy as well. I can check the radar and get alerts straight from my wrist even if I have left my phone at home.
For longer range stuff it pulls in proper models like ICON, GFS and ECMWF so you get a decent 72 hour forecast and a 14 day outlook. Alerts are customisable which means you only get pinged when it actually matters. You can set them by location, how heavy the rain will be, or even the type of precipitation.
Another feature I really liked was the AI assistant that gave me weather recommendations and news directly in my notifications. Really made it easy to take precautions during certain weather conditions like rain and fog.
As a Photographer, taking expensive gear out when the weather looks a bit patchy, was made a whole lot easier when I could check the app and get a near real-time update on what was going on above! Absolute life saver.
The Free vs Paid Experience
The free version gives you the core radar and basic alerts which is already pretty useful. That said, quite a few people in the reviews mention the ads can be annoying, especially when a video pops up right in the middle of watching the radar animation.
If you use the app a lot like I do, the paid version (Essential or Pro) gets rid of the ads and adds more favourite locations and extra history. Pricing feels reasonable for what you get.
Users seem to agree on the accuracy. One person called it the most accurate app they have tried down to the minute. Another said the rain notifications are spot on and give a proper heads up before sudden downpours hit.
There are the odd complaints about occasional glitches or slow loading after updates, but the developer does seem to push fixes out regularly.
I personally never saw any of those issues!
Final Verdict
Overall Rain Viewer just feels more reliable for UK weather where rain can be really patchy. One minute it is dry, the next your street is getting hammered while the next one stays fine. That level of detail makes planning much easier whether you are cycling, walking or just trying to time your commute.
It has earned a permanent spot on my home screen and my Apple Watch. If you are fed up with weather apps that get it wrong, give Rain Viewer a try on the App Store.
It works on iPhone, iPad and Apple Watch, as well as on Android if you so please.
The free version is worth downloading to see what you think.
Honestly it’s a solid radar app that keeps getting better with updates.
So go give it a try and stay ahead of the weather!
