We've all seen it happen. A great technology, service, or platform comes out, but without a solid base of users and apps, it fails to gain traction. Google wants to see the Fit API work out, and developers have been called upon to help make that happen. If you know how to write an Android app, and you've got a great idea for something that will get people off the couch and into the gym, you're invited to join the Google Fit Developer Challenge.
Recon Instruments, creators of wearable goggle technology powered by Android called MOD Live that we got so excited about at CES 2011, have officially announced the impending release of an SDK for Android, due for launch in May 2012. Recon also announced Polar, the first app made using the SDK, that connects a Polar WearLink+ heart rate monitor to MOD Live and allows the MOD display to become a "biometric reader that delivers an athlete's heart rate in real time while they ski or snowboard."
For those not in the know, the Polar WearLink+ transmitter is essentially a Bluetooth-enabled heart monitor that can send heart rate information to a variety of compatible applications (in this case, the new Polar app).
