Fitbit said Tuesday it is buying Twine Health, a small Boston-based startup that helps people manage chronic diseases such as diabetes and hypertension.

Why it matters: Fitbit has been increasingly focused on the health space as an avenue of growth, working to show its devices can monitor and improve health, not just count steps and track sleep.
