Millions depend on the Apple Watch for communication, productivity, and fitness tracking. With such a vast range of personal information in a wearable, protection from unauthorized access becomes more critical. The Apple Watch passcode is a four to six-digit PIN that serves as the first line of defense. When placing the Apple Watch on the wrist, the user is promoted for this passcode before using the device.
Recent models of Apple Watch are capable of fast charging with the right equipment on hand. Apple says the feature delivers battery power from 0-80 percent in just 45 minutes. So which Apple Watch models support fast charging, and what is needed to make this happen?
Drinking the right amount of water everyday can improve health. Apple Watch users can install a variety of third-party apps to track daily water consumption. There's also an easy way to use built-in software to store water log data directly to the Apple Health app.
Sometimes Apple Watch prompts to record a workout automatically. While this feature can be helpful, if the user forgets to end the workout it leads to misleading data saved to the Fitness app. Other times a workout might be extended after recording has stopped, which leads to the question of how to manually edit a workout entry.
Don't look to the Fitness app for editing workout length. Workouts can only be viewed in the Fitness app. The only way to have control over workout data is through the Health app on iPhone.
Apple has been working on non-invasive technology to measure blood glucose levels. These sensors would use optical absorption spectroscopy to calculate blood sugar levels through the skin, making pin pricks for blood samples unnecessary. Rumors have pointed to a future Apple Watch with built-in glucose monitoring in development.
