Android Wear is to wearables like smartwatches, as Android is to smartphones – it underpins both form and functionality. Google has announced Android Wear 2.0, a version that makes the operating system competitive again.

Smartwatches, particularly those with good health and fitness underpinnings, are still a niche, but growing market. Samsung may well have made its new Gear S3 the best, certainly the most comprehensive, smartwatch with fitness benefits so far.

It is water resistant, mil-spec, allows you to make and take phone calls, plays music, has GPS, wireless charging and a has a raft of new features that don’t need a tethered phone to work.
