What it is: The “killer” app for the Apple Watch is real-time health monitoring.
When the Apple Watch first appeared, critics dismissed it as a gimmick. That’s because even Apple couldn’t define a specific use for the Apple Watch at first.
The whole purpose of technology is to solve a problem that was too difficult or impossible to solve previously. The PC made computers accessible to more people beyond the mainframe and minicomputer users. What made the PC useful was the spreadsheet, first embodied by VisiCalc and then by Lotus 1-2-3. People bought PCs specifically to use spreadsheets.
When the iPhone first came out, it represented a giant improvement over existing mobile phones, but also gave you a computer in your pocket. Combined with mobile location tracking, the iPhone defined how smartphones work, which eventually led to location tracking services like ride-sharing services.
The Apple Watch first appeared with no specific purpose in mind, but the latest Stanford study indicates that the Apple Watch does a decent job detecting heart abnormalities. To detect this usually requires expensive equipment at a doctor’s office, but the Apple Watch is bringing this capability to the masses. That makes real-time health monitoring the real killer app for wearable computers.
If you’re concerned about your health, then the Apple Watch is for you. For people who still refuse to buy and use a wearable computer like the Apple Watch, they’re essentially telling the world that they either can’t afford a wearable computer or they don’t think their life is worth a few hundred dollars.
The next step for wearable computers will be health enhancement. That can come with smart glasses that enhance a user’s vision while also tracking health conditions at the same time. Real-time health monitoring and enhancement is the ultimate goal of wearable computers.
