A new report for Reuters says that app makers are struggling to come up with the kind of “killer app” that will be a winner for the Apple Watch in the way that Instagram or, more recently, Snapchat was for the iPhone. The report notes that Apple has blocked certain features of the Apple Watch, including its gyroscope and accelerometer, on the initial WatchKit developers’ kit, but won’t reveal exactly why this has been done.
Other aspects of the Apple Watch third-party developers can now yet tap into include the ability to wake up companion iOS apps, using the Taptic Engine, heart rate tracking, Force Touch, and a variety of other innovations.
“The limitations are discouraging,” one engineer, developing a Watch app to control a Tesla Model S, is quoted as saying.
