To the point!

Thank you for not using geo location map data. The other two apps in the App Store Story do this and for those of us who don’t live in the locales these apps are featured for it shows local weather instead, without the benefit of the cool graphics.

Love the cute animated whale and boats. Will Karl be a future additional layer? Maybe some interesting landmarks or geo features to denote elevation?

Lastly, in the settings section, it would be great to have a few other to give feedback via Twitter or email items like those listed in apps like Transit or the like.


Simple & Elegant

I love the concept. Beautiful color coded maps of temperatures. The data seems to be based on forecasts, not live info. I use it every day because it’s very helpful and I can quickly understand temps in a glance. Living in the East Bay, working in SF where temps can vary by 5-10°, this is great!!

Of course there is still room to improve. For example, I wish we could have a view for Marin/Sonoma/Napa so I can plan my weekend coastal hikes and trips to wine county. I also wish the app could do more with live data easily available, but also keeping things as simple and clear as they are right now. ☺️


How can there be such a descrepency

The app says it uses Wunderground for the temps. Well it’s usually a 5° a 15° between this app and the actual Wunderground app. How about a bit of accuracy. It’s tough enough living in SF and dealing with the microclimates from neighborhood to neighborhood. Now we have an app that has microclimates from their mother app. Fix it. Till then, this app goes in the trash
