When Fitbit launched the Blaze fitness watch in 2016, it made sense that the company might also be working on a more full-featured smartwatch, too. When Fitbit bought Pebble, Fitbit's CEO confirmed that fact. Unfortunately, the product was reported by Yahoo! to have a ton of issues that pushed the planned launch from this past spring to the fall. Bloomberg is now reporting that the project has lost several people who were working on the smartwatch. The sources also say that Fitbit was unable to close a deal with Spotify and that technical challenges have delayed the completion of an app store, an essential component of any smartwatch ecosystem.
