When Samsung announced the Gear 2 and the Gear 2 Neolast month, the news came with the confirmation that the company was dropping Android from both devices. Instead, both smart watches are powered by Tizen. This may not mean all that much for consumers in the short term, but it does impact developers. For you, Samsung has just shared the first version of the Tizen SDK aimed at wearables. This is what you need to grab if you intend to build apps for the company's two intelligent wristwatches.
