Spotz: Location-based self awareness (2011-2012) 

Spotz is an Android app that recommends things to you based on 'buzz' created by others for those things for e.g. you could follow #bestchocolatecake and the app will show you what places have been tagged with that buzz. Similarly you can follow places that have specific tags of interest to you for e.g. you could follow #healthy or #geeky and the app will show you what places near you have #healthy or #geeky as their most popular tag. The app playfully generates a persona visualization for you to share on social media based on the most popular tags for the places you visit. This also allows you to friend and/or follow others with similar personas as you to explore and discover places of mutual interest.
