Smartwatch company Pebble has been making a number of improvements to both their watches and corresponding apps. Three years ago the company launched a wildly successful Kickstarter campaign, and they are set to repeat their success with the new Kickstarter for their next generation of watches: the Pebble 2, Time 2, and all-new Pebble Core. The latest campaign has already well surpassed its goal of $1 million dollars and is currently sitting at a comfortable $10.6 million with almost three weeks still left to pledge.

Unlike some other fitness app developers, Pebble likes to stay transparent in their methods. They have recently published the algorithms they use for their apps. The mathematically-minded can read an overview of these algorithms written by Nathaniel Stockholm, a Ph.D. student in Neuroscience at Stanford University.

But it’s not just physical fitness that Pebble is consistently developing more accurate algorithms for. The company has recently updated their Happiness App. This app offers a one-week program in which the user catalogs their moods and environment; the resulting feedback should help the user improve their daily habits. According to the Kickstarter website, “you can give input on other factors in your environment to get feedback on how those factors correlate to your fluctuating mood.”

The Pebble Core is expected to retail for $99, the Pebble 2 for $129, and the Time 2 for $199.
