Samsung today announced the release of a new Tizen Software Development Kit for the recently introduced Gear S smartwatch. The SDK will let app developers tap into network, call and location based APIs, as well as notifications and the device’s various sensors. While other companies are investing heavily in Google’s new Android Wear platform, Samsung is clearly still hoping that developers will embrace its own Tizen-based platform. It hasn’t completely abandoned Android for its wearables, however, as it also recently launched the Android Wear-powered Samsung Gear Live.
