For years I used an application called Radar Now, until I found this App called My Radar http://myradar.com/ a few months ago 
This little puppy has served me well while running around on the Skiff, and really does not appear to use a lot of data when I cannot reach a local WiFi hotpots.
What I also like and I feel some may not 1st find, is by going into the layers setting, one can really fine tune this application and tweak the display to suit your needs. For myself, that was wind direction so you may to want to also enable it and fine tune it color wise for best viewing on your device
Now this video below is a extreme example, but you can see how the application displays winds so you can help see when Storms may pop up.
Here in Florida the majority of our heavy (sometimes insane) afternoon downpours is due to what is called Sea Breeze collision Storms and is a air mass battle between the Atlantic and the Gulf as it marches across and then smash into each other across the State as the day progresses and gets hotter. Here is a good example video of such...
So being able to see that air flow movement on your screen along with a good eye to the sky... You might be able to get a early indication of when to head back to the dock before you feel like you are trying to drive your boat through a car wash
As I have discussed with others, radar only shows where it is now, not where it is always headed or worse yet, pop up over you 
Try it and see how it works for you? Hard to beat free when it comes to trying pretty much anything
Stay safe!
