As the Apple Watch stalls, Fitbit has grown, with a 25.4 percent share of the market and 5.7 million units shipped in the second quarter, compared to a 24.5 percent share and 4.8 million units in the first quarter. Because the company's name remains "synonymous with fitness bands," IDC believes its reign will continue in the wearables market. Until smart wearables with various functionalities can justify higher prices to consumers, a more affordable wearable with "a clear value proposition," i.e. fitness-focused features, will help Fitbit remain on top of the market, according to the firm.
