Here a tracker there a tracker … Apple Health to the rescue?

Getting all your activity/sleep etc data in one place is challenging. The makers like fitbit etc have no motivation whatsoever to allow you to have devices from different companies. In fact, they use it to trap you into their ecosystem. If you happen to change trackers, do you want to change your scale? Of all the companies I’ve played with Fitbit, Polar, Misfit, and Xiaomi only Fitbit allow you to export your data. And then it dawned on me, in the Apple world there is a bridge to bring this data in one place, Apple Health! So let’s have a look at this …

When you install an app that supports Apple Health, you can control what amount of access it can have to Apple Health, ie what it can read and write. When you uninstall an app you can also choose to remove all data in Apple health from that app. You can easily see what sources currently have read and write access and tailor it as you see fit.

For this to be a savior you need to keep an eye on how well the individual app works with Apple health. I found Garmin connect had some anomalies that were polluting the sleep data. It seems Garmin did not think of the possibility that you might not always sleep with your Garmin device and it used the definition of normal bed time (which is used to mute the device) on those occasions to populate your sleep? WTF.

Fortunately it’s pretty easy to simply remove Garmin Connect’s access to just the sleep data.

Fitbit have chosen for now to completely ignore Apple Health, likely to keep your data in their vault. Fortunately there is an app out there that simply takes your fitbit data and pushes it into Apple health called Health Sync. It works well.

Fitbit do an incredible job of taking data from multiple devices and merging them. You can wear your Flex for part of the day and switch up to a different tracker and it merges them nicely. Apple Health however makes not attempt to do this. It does however allow you to prioritize which data is likely to be more accurate.

Additionally you can manually edit and delete entries easily.

Data can be exported from the Apple health app, but I see no way of importing it. This is potentially a challenge if you don’t use the backup/restore method of migrating to a new phone at some point. The exported data comes out in an XML file that is challenging at best to do anything with. Fortunately there is an app called QS Access that will allow you to export exactly what you want to a CSV that in turn can be imported into Excel for graphing and analysis.

So an in all it can be done, but definitely could use some work by Apple …
