Browserstack has an online tool that allows responsive design testing across different mobile devices.
I was curious if it would catch some of the display differences that Google has in representing the local pack across devices with different OSs and display sizes. The differences are interesting and legion.
There are some caveats like the fact that it uses a European proxy server and doesn’t reflect things like Google Now. Who knows how many other display types it doesn’t show as there is often variety by browser types, location and searcher as well as device type. I am not sure that it captures the iPhone 6 accurately either.
Regardless it shows the amazing diversity of how a single local search result might show across devices. When was the last time you saw a 7 pack with red pins on the desktop (Windows)? This variety also demonstrates one of the reasons that ranking tools are often inaccurate.
