We launched pressureNET 3.0 this morning. It's an open source Android app that collections barometer measurements from phones and tablets, and sends the data to atmospheric scientists for analysis. Regarding traction, we'll see! The app itself has more than 17,000 downloads and we've collected more than 10,000,000 measurements. Version 3.0 is a very big update, the first that includes proper visualization and sharing of data, so I think we're doing well.

Here's our announcement blog post: http://www.cumulonimbus.ca/pressurenet-3-0-sharing-visualiza...
