Even though smartwatches are getting all the media buzz these days, fitness-focused devices are expected to dominate the wearables space until 2018, according to Juniper Research. At the end of 2019, the situation will look different with 110 million people using fitness wearables, and 130 million – smartwatches.

The research firm noted that it’s getting tougher to distinguish between the two categories, with fitness wearables — such as Samsung Gear Fit and Microsoft Band — including features such as notifications and call-handling capabilities.

Nevertheless, the low-cost of fitness trackers as well as their obvious use case will keep their sales growing in the years to come. Also, these sort of “simpler devices” are more popular in the professional sports world, where wearables are becoming part of the training regimes of many teams, and form the majority of the market for clothes with integral fitness tracking. Over time, Juniper expect that wearables-measured performance will become a standard part of hiring practices, and potentially also players’ contractual obligations.

When it comes to wearables’ healthcare use, the research noted that while future electronic healthcare records will drive the use of dedicated wearables, the price of the devices and dependence on smartphones will hold them back from full adoption by universal healthcare systems.

“The use of wearables to track health shows promise, but such devices will not reach their full potential until they can become less dependent on mobile devices to relay their information, in addition to meeting healthcare data storage and relay requirements,” research author James Moar noted in a statement.
