How are Very Active Minutes registered by FitBit trackers?

[alexbadut]

Hi,

We want to reward users for a loyalty mobile app with points for their FitBit runs, so we rely on VeryActiveMinutes that are incoming from the tracker via the API. 

Is there a more detailed explanation on how veryActiveMinutes is actually measured by Fitbit trackers? 

Moreover, if there is a significant difference between how different models register veryActiveMinutes, it would be really helpful to learn about them. 

Kind regards,
Alexandru

Take a look at this article.

Apparently there is a difference between Active minutes and Very active minutes, so your link does not help much.

Fitbit's active minutes goal is a sum of veryActiveMinutes and fairlyActiveMinutes values in the API. The level is determined by multiple factors for how vigorously active a person is. More information is here, but Fitbit does not disclose the exact methodology between the two levels.

edit: never mind, I've figured it out.
