We're calling this "wearable-ception." Misfit's Shine is a waterproof fitness tracker. With an accelerometer and 5 ATM rating, so (potentially) is the Pebble smartwatch. Color us surprised then, to find out Misfit and Pebble are partnering to re-imagine Shine as a Pebble app. Misfit's experience and bespoke fitness tracking software is being shoe-horned into a watch-friendly format, and will be available in the Pebble appstore today -- no Shine required. If you already have a Shine, and are an iOS user, an updated app will fold in support for Pebble watches, should you prefer to keep things separate. The updated app also includes some new metrics, such as calories burned, and distance traveled. Pebble already has a number of fitness apps, but the company claims this is the first stage in an ongoing collaboration with Misfit -- so expect even more fitness functionality in the future.
