There's also an update to Pebble Health, the built-in fitness tracking app it launched last December. In addition to tracking your steps and sleep, there's now an API that will let developers integrate Pebble Health stats to different apps and watchfaces. There's already one such watchface available, with more to come in the future. For those with a Time-series watch, you can also now switch between miles and kilometers in the Health app.

Rounding out the set of improvements are more descriptive MMS notifications, new low battery warnings that tell you how much time you have left before you run out of juice, a new low power mode that'll shut off extraneous features but still keep your Pebble functioning as a watch, support for Cyrillic characters and the usual performance boosts. That's a hefty set of new upgrades, so if you have a Pebble watch, you can go ahead and get the new apps from both the Apple App Store and Google Play starting today.
