Recording sleep with wearable devices seems to be a natural function. From the earliest Fitbit and Jowbone bracelets, to now the bracelets of Xiaomi, Huawei, and Huami, there are no other bells and whistles, but sleep tracking. It must be no less.

But the “hidden rules” of this smart wear world seem to be not applicable to Apple’s Apple Watch. Although the product has reached the fifth generation and can even detect heart problems such as the risk of atrial fibrillation, it is still beautiful today. And expensive smart watches still do not support sleep detection and recording.

There is no official, third party to make it. An app called NapBot has been on the App Store a few days ago, and the software works very simply. You only need to wear Apple Watch while you sleep. The NapBot app on your watch will automatically detect that the wearer is sleeping and start tracking. Sleep status, heart rate, and noise level. The iOS app visualizes the data recorded by the watch and syncs it to the Health app.

The most interesting thing about NapBot is its sleep tracking implementation. Instead of relying on fixed algorithms, the app uses iOS 13 and watchOS 6 to add the CoreML machine learning framework to understand how users sleep. This means that although the error may be larger at first, it will get better and better as the device becomes more aware of your sleep habits. And this set of modelsThe model will also learn from the data obtained in the last few nights to learn about your recent sleep patterns and habits.

NapBot for iOS 13 and watchOS 6, the app itself is free, but features like historical sleep recordings and trends are subscriptions, and can be subscribed for $0.99 per month or $9.99 for one year.

Apple Watch There have been a lot of recent news about sleep tracking, Ai Fan has also reported several times before. However, from my personal point of view, it is difficult to take the Apple Watch for sleep recording. The biggest shortcoming is still in the battery life.

Even if the noise monitoring is not turned on, only the screen of the Apple Watch Series 5 is turned on. After using it for a day, the power of the Apple Watch is only about 30-40%. It is absolutely impossible to support it until the next day. . This means that Apple Watch needs to be charged every day, and the best charging scene is to charge during sleep at night.

Putting Apple Watch at night also means that you are actively detached from the notification system of your mobile phone.This usually results in better sleep quality without being disturbed by some useless notification content.

So, Apple Watch is far from recording the best wearable device for sleep, unless you are really restrained in using it, you can still have more than 60% of the power remaining in one day, and because the night tracking involves multiple sensors, It is very likely that the next day it will take another charge to meet the next day’s use.

But according to the recent exposure frequency, the official sleep tracking app is expected to come to Apple Watch soon. If you really care about your sleep record and don’t want to pay for a third-party app, then thenWait a minute.
