The most prominent opponent of Pear is B.Elion.

It was initially a big medical company, and one of the products they produce was a pregnancy tester. They recently changed its design more fancy and womly, and also made it interact with the smartphones, and had a huge success.

From that achievement, they discovered a lot of opportunities from blending their medical technology with the digital products. Now they announced that their next step is to make the healthcare smartwatches. A fierce rivalry between Pear and B.Elion in the smartwatch market is expected next year.
