Under Armour: the USA's tech-enhanced fitness giant is ready to conquer Europe

This could be great news for HTC, as well. It's a company that's been struggling financially, even as it triumphs with tech fans and journalists. The Taiwanese smartphone king has a reputation for quality design, and if it can be the company that finally cracks the wearable market with something functional and beautiful, it could find itself back on the inside track from cult favourite to mega brand – a bit like UA in Europe, in fact.

Even if their partnership starts with nothing more than a native app on the upcoming HTC One M9, that could be extremely useful to them. Apple and Nike shared a mutually beneficial partnership when the iPhone launched. So too could Under Armour and HTC.
