A selection of Android Wear watches. Google According to data from Google Play (compiled by The Overspill), there are just 1.9 million Android Wear devices in use today, up from 1.2 million in February 2015. This figure is far behind the Apple Watch which has seen sales of around seven million since its launch in April.

Every Android Wear device needs the associated app on an Android phone to function and so tracking downloads of the Wear app indicates how many watches have been sold and are in use.

On its own, 1.9 million Wear devices seems impressive but the total number of eligible Android users — i.e. people who use an Android phone that is version 4.3 or above — sits at around 949 million devices, meaning that Google has converted just 0.2% of its user base when it comes to wearables.

The trend in smartwatches appears to buck the trends in smartphones. Android is by far the largest operating system by user count, with over 1.4 billion devices, according to Google CEO Sundar Pichai. Apple has sold around 750 million iPhones, according to CEO Tim Cook, and yet the Watch is more popular.
