Groupon acquired Glassmap in January 2013. The app is now shut down.

Glassmap is an iPhone and Android app that lets you show your friends where you are and what you are up to.

Glassmap is the best way to show your friends where...
See More you are and what you are up to! You can share your exact location and the photos you take with your friends in real time. Use it to coordinate meetings and hangouts, keep up with loved ones, and serendipitously discover who’s around you. With elegant privacy controls, rock solid performance, free in-app chat messaging and more, Glassmap is the best location sharing app available today. Best of all, it is FREE for iPhone & Android!

Features
-Create a Glassmap account and add friends via Facebook, Twitter, your contacts, or nearby Glassmap users.
-Share, like, and comment on the photos that your friends and others around you post. Explore and add content to the world via Glassmap!
- Seamlessly start conversations with free in-app chat messaging and VoIP calling. Don’t have anything to say, but just want to give someone a nudge? Send a Wave!
- Power-efficient, automatic background updating means no bothersome checkins. Continued use of GPS running in the background can dramatically decrease battery life, but our proprietary "relay" technology eliminates battery draining issues.
- Find friends who aren’t on Glassmap via the search function, which can request anyone’s location through a text message to his or her smartphone.
- Intuitive privacy controls let you block specific people or completely stop sharing your location. Glassmap further keeps your information safe with state of the art security.

Requirements
- iPhone or Android (2.2+) phone with GPS and internet connectivity
