I use and enjoy my AIR and my new SKY.
I find the use of NONE on the app “home page” when there is no Rain to be inconsistent with other design choices.
On the app home page, every reading has some unit of measure shown; deg F, inHg, Today, mph, UV, week etc.
However the RAIN value, if there has been no rain is NONE. And nowhere on the rain “bar” does it say rain.
Why does this matter - at least for me, at first glance, it takes some time for me to discern what the NONE refers to. I have to look over to the right and guess that inches in past hour inches in last 24 hours refer to RAIN. It is immediately clear, in every other “bar” what is being measured/displayed.
Please consider displaying something like, 0 inches Rain instead of just NONE.
Just my thoughts.
