The Fitbit app for Android supports the healthconnect API, which is positive. However, the data taken in by this API is not being utilised to its full potential. For example, when I request a PDF of my health data, it doesn't include healthconnect data that the app has taken in, such as my blood pressure. While this may be an issue for iPhone users, it can be easily worked around by utilising Apple Health or third-party apps using Fitbit's API.
Additionally, the Fitbit app doesn't write healthconnect data to other applications, which is inconvenient if you're trying to use Fitbit as your primary health application. For instance, I like taking my body temperature, but that data isn't sent from the Fitbit app to other applications through healthconnect, so I have to use Google Fit to record it.
Fitbit needs to improve and be more on par with other health companies like Withings. There's a lot that Fitbit can do in terms of making itself more health-focused. Fitbit makes great wearable devices, but they could expand into other health devices like blood pressure monitors and more in-depth scales that can measure body fat percentage, bone mass, and body water mass.
It's strange to see a company owned by Google, which released an API dedicated to sharing health data, not using that API to its fullest extent. The fact that Google Fit utilises the API better than Fitbit is unacceptable. I should be able to use Fitbit for all my health data needs, I shouldn't really need to utilise Google Fit whatsoever. Fitbit allows users to put in blood glucose levels manually and it should also do that for blood pressure as well.
