Since we’ve seen a tree tweet, why not check out a fitness app in Barcelona? We did this a couple of days ago, on the Mobile World Congress floor, where we found a pretty nifty health-related app in action on an Android app. Said app connects to a harness attached to the user and shows on the smartphone important info, like heart and more, that you’ll find out below.

Transmitting via Bluetooth, the harness details stuff like ECG, heart rate, breath rate, skin temperature, rate of activity, blood pressure and saturation of oxygen. A doctor can use this software to monitor up to 7 different patients. A bio harness is also involved, but you can test the app even if you don’t have it, in demo mode.
