Realtime heartrate gathering from inspire hr

[jashdoshi]

Hello,

I am trying to create a flutter app which tracks real-time heartrate of user for my college project. I have a fitbit inspire hr. Is it possible to get realtime heartrate data from it into my flutter app?

I'm afraid not. The Web API doesn't provide real-time data, but is only updated whenever the watch syncs (every 15-20 minutes?). The Device API can provide real-time data, but the Inspire can't use that.

Okay, is there any other way you could suggest to get realtime heartrate into my flutter app?

A Fitbit OS device (any Versa or Sense) could do it. But you'd have to write some clever software to transfer the data from the watch via the companion phone to your app. It's possible but not trivial.
