There have been plenty of rumors swirling around Apple’s smartwatch, commonly dubbed the iWatch, and now the Wall Street Journal reports that it will have a few designs with multiple screen sizes, and could launch as early as October this year. In particular, the smartwatch is said to feature more than 10 sensors, some of which are specific to health and fitness tracking.

Earlier this month, Apple announced HealthKit for iOS 8, which lets third-party apps store data for quick access and easy reading in one central place using the Health app. A sensor-equipped wearable device makes sense for its renewed push into the health sector right now.

The WSJ cites a component supplier as saying that Apple plans to ship between 10-15 million of its smartwatches by the end of this year.
