David Singleton, the king of Android Wear. Mike Nudelman/Business Insider In February this year, Google's smartwatch boss painted me a rosy picture of the future of wearable technology.

The wrist is, David Singleton said, "the ideal place for the power of Google to help people with their lives."

He envisioned a future in which ubiquitous smartwatches would monitor your health, control your world, help you communicate with friends — even give you "powers" you don't have today.

But 11 months down the line, the future of Google's smartwatch vision looks uncertain.

Moto just put its smartwatch plans on hold.

Google's smartwatch program, Android Wear, follows a similar model to its Android mobile operating system. It makes the software, while hardware partners build the devices it goes inside. When it works (like it did with Android) it can be spectacular— letting the software rapidly scale, reaching millions or even billions of users. But it also puts Google at the mercy of the whims of its hardware partners.

The Moto 360 smartwatch. Motorola This week, The Verge reported that Lenovo-owned Moto — an Android Wear partner — is pausing its smartwatch efforts "indefinitely."

It had previously bought out the Moto 360 in 2015, but failed to release a new device this year — and has now confirmed it won't released a new smartwatch to coincide with the launch on Android Wear 2 software in 2017.

The company does not "see enough pull in the market to put [a new smartwatch] out at this time,: head of product development Shakil Barkat said. "Wearables do not have broad enough appeal for us to continue to build on it year after year."

Huawei and LG, two other Android Wear smartwatch makers, also did not release new devices in 2016. Typically, smartphones are released on an annual basis (or more frequently). (There are also rumours that Samsung is ditching the platform. It already has an alternative smartwatch operating system, Tizen.)

The data is murky, but it doesn't seem great.

Google has never broken out Android Wear sales, so we're forced to turn elsewhere for estimates. Here, analysts disagree on smartwatch sales, as this round-up from TechCrunch illustrates. IDC reckons that sales have plummeted 40% year-on-year to 2.7 million in Q3 2016, while Canalys says quite the opposite: That sales jumped 60%, up to 6.1 million.

Whoever's right, two things are clear.

First, this is not a category that is setting the world on fire. Google cofounder Larry Page has a "toothbrush test" that the company's products should be "used daily by billions of people," according to Bloomberg. So far, this is clearly not happening.

And second, Apple is wiping the floor with Google. Both estimates that Apple (who also doesn't break out smartwatch sales figures) amounts for nearly 50% of all sales — 46% according to Canalys, 41% according to IDC. That other 50% includes Samsung devices (which run Tizen rather than Android Wear), Fitbit, and other non-Android Wear wearables.
