Facing a stiff competition from rivals in the mobile space, Apple seems to have decided to go a step ahead and expand into new product categories. But the new product Apple is reportedly working on is no less than a surprise.

According to a report from the San Francisco Chronicle, the Cupertino-based tech giant is planning to expand into both medical devices and cars.

If the report is to be believed, the company is currently working on a device that could predict heart attacks by listening to the sound of your blood. For this new device, Apple is working with audio engineer Tomlinson Holman, who is known for inventing THX and 10.2 surround sound, said the report.

Rumours are doing the rounds that, besides medical devices, Apple is also planning to foray into automobiles. However, there are no clear reports that can elucidate Apple's interest in cars.

The San Francisco Chronicle report said that Apple's Adrian Perica had met with Tesla CEO Elon Musk last spring, but there are no details as to what was the agenda of the meeting and what all disucssions had taken place during the meeting.
