Hands-down most accurate weather for The Bay!

I don't know how they do it, exactly, but it works! This is the only weather app I check in the Bay Area. Every other app seems to use data from SFO which can be more than 10*F warmer than other parts of the city on certain days. Whenever I have BBQs, I always get asked, "what's the weather like in your neighborhood?!" This helps.

My primary suggestion would be to extend the regional map northward, or perhaps to split the regional map into "North Bay" and "South Bay" to include coastal Marin, inland Marin, Petaluma, and Napa. Giving just one temperature for Marin is analogous to why this app was created in the first place for SF.

I also wish the forecast would extend beyond 24 hours but I recognize that may be too difficult to accurately predict.

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.

Must have in the SF Bay

It’s one of those hyper-local apps that you just need. It replaced another app that gave simple, real-time, weather data that was left to rot. Thanks to a hackathon this cute app emerged. I pay for it because it’s useful and useful apps deserve financial support, especially given how trivial the amount is. If you live in SF you need this period, but it supports the greater Bay Area so everyone around here should have it.
