I have tried many activity trackers, but after the release of the new Jawbone UP and Android support, the UP is my preferred choice. Jawbone just announced their new UP Platform (PDF file) that takes the UP even further and allows 3rd party developers to integrate their service with all of the amazing data the UP captures. To continue solidfying Jawbone's place in the fitness market, they also announced the acquisition of BodyMedia. The latest UP software for Android and iOS is pretty powerful in itself and I particulary like the ability to view all of my data and also share parts of it with family and friends. With the new UP Platform support, we see 10 apps/services at launch that you may already be using for your health tracking. The current 10 supported apps and services include IFTTT, LoseIt!, Maxwell Health, MapMyFitness, MyFitnessPal, Notch, RunKeeper, Sleepio, Wello and Withings. Read the full story at ZDNet.
