Pebble's software and services won't be affected at least until the end of 2017.

Following its acquisition by Fitbit, Pebble has detailed upcoming changes to its software and cloud-based services. The company is stating that its smartwatches will continue to work at least until the end of 2017, with the Pebble SDK, APIs, mobile apps, and the Pebble appstore set to remain in service.

From the Pebble blog:

Fitbit is going out of its way to keep Pebble software and services running through 2017. To be clear, no one on this freshly-formed team seeks to brick Pebble watches in active service. The Pebble SDK, CloudPebble, Timeline APIs, firmware availability, mobile apps, developer portal, and Pebble appstore are all elements of the Pebble ecosystem that will remain in service at this time. Pebble developers are welcome to keep creating and updating apps. Pebble users are free to keep enjoying their watches.

Our first action to preserve the Pebble experience far into the future will be to update our mobile apps, loosening their dependency on a patchwork of cloud services (authentication, analytics, app locker, etc.). Expect this update in the coming months. The mobile app updates will ensure the operation of core Pebble functions, even with cloud services discontinued—they won't break functionality.

The upcoming update won't hamper the functionality of Pebble Health, which feeds "directly into the Pebble mobile app, Apple HealthKit, and Google Fit." Pebble is also evaluating features that rely on third-party services — dictation, messaging, weather, and others — and will make a final decision soon over how long it can keep those features running.

For now, it looks like you'll be able to use your Pebble devices for at least another year, although what happens after that is uncertain.
