Anticipated Fitbit smartwatch rollout hitting some last-minute snags

Fitbit Inc., months away from the debut of its smartwatch, has lost several people working on the project and fallen behind on its app store — putting in peril the company's most important product in years.

Hard hit by the sinking popularity of its fitness trackers, Fitbit has bet its future on the smartwatch. But such devices are typically wedded to an ecosystem of compatible devices, apps and services that lure then lock people in. While Fitbit's watch can play music and handle payments, according to people familiar with the product, a discussed partnership with Spotify failed to materialize and technical challenges mean the app store may not be ready when the watch arrives this fall. Many app developers, meanwhile, are unenthusiastic about Fitbit's watch.

"I'm more focused on the big boys like the Apple Watch and Android Wear," says Damian Mehers, who developed a version of Evernote for Samsung's Galaxy Gear watch. "I could consider developing for Fitbit if there was a compelling device and a large enough user base. I think it will be challenging to establish credibility."

Like many other developers, Mehers says the challenge is exacerbated by the fact that wearable devices still haven't caught on widely, meaning they're less desirable to write apps for than a smartphone.

In an emailed statement, Fitbit said the development of the smartwatch and third-party apps "are on track" and that "any claims that the developer program is struggling is false." The company said it's "well positioned to succeed."

The global wearables market is expected to grow about 20 percent this year to 125.5 million devices shipped, according to researcher IDC. But Fitbit's watch will be competing with not just Apple but dozens of cheaper Android products. Fitbit recently lost its position as the top seller of wearable devices, falling behind Apple and China's Xiaomi Corp. Investors are skeptical of the company's prospects, pushing the shares down 55 percent in the past 12 months. They fell a further 2.41 percent to $5.27 at 10:49 a.m. in New York Friday. And while Fitbit has a loyal base of users that it can push the new device to, analysts say the company could struggle to get traction outside that fairly narrow niche.

Last year, to help jumpstart its smartwatch effort, Fitbit acquired technology developed by watch maker Pebble, which shut down after failing to compete in a market that has taken off more slowly than expected. Pebble developers helped form the core of Fitbit's smartwatch team in California, but most have since left, according to a person familiar with the situation (although a separate group of Pebble alums in Ottawa remains intact).

The Fitbit watch is expected to sell for less than $300 and will run a custom operating system based in part on the one that powered Pebble watches versus a more ubiquitous operating system like Android Wear. Choosing Wear would have immediately given Fitbit a vast ecosystem of applications, established developers and support of the Google software brand. Instead, Fitbit has devoted resources to creating a custom operating system, which requires the development of an entire ecosystem and risks a lack of developer support.

Fitbit played up Pebble's strong ties to the developer community as a rationale for buying its intellectual property. But a person familiar with Fitbit says the company has done little keep the relationships going. Hoping to woo app makers down the road, Fitbit will let developers write software in a web-based programming language called JavaScript, which some say makes it easier to create apps that will run on the watch.

Fitbit also plans to follow industry practice by putting its app store not on the watch itself but on Apple and Android phones. Users would download apps on their phones, then beam them via Bluetooth to the Fitbit watch, the same way Apple and Google do it. The app store, while delayed, could conceivably be ready for the watch's launch.

After the partnership with Spotify foundered, Fitbit began working with Pandora Media. Landing Spotify, the world's largest paid streaming service, would have been a coup. Instead, Fitbit is working with a company struggling for relevance after clinging to an internet radio model. The feature Pandora is working on will let users store music on the watch, a person familiar with the plans says. Spotify and Pandora declined to comment.
