Apple was the top wearables vendor in Q1 according to market analysis firm Canalys. A rival analyst from Asymco also placed Apple at the top, but with a higher total of devices shipped. Canalys put the number at 3.8 million. the other at just over 4 million.
Disagreements like this are possible because Apple itself doesn’t reveal how many smartwatches it sells. Still, both groups of analysts agree that Apple Watch leads the market.
