My go-to weather app

Love this app for San Francisco weather, particularly when the west side can be so different from other parts of the city.

Treasure island is SF too!

Another app that ignores us on Treasure Island/Yerba Buena island.

Glen park

I love your app, but it’s missing my neighborhood Glen Park
Can you put it on?

Would be 5 stars if named properly

Love the app, hate the name; everyone knows our fog is called Lola.

Isn’t Marin part of the Bay Area

We’re more than Sausalito and have plenty of our own microclimates but you lump everything under either Marin or Sausalito. I’d be happy to go Pro if there was more information available for Marin - but there’s not.
