Ovia can connect with Fitbit and Apple Health.
From Fitbit, Ovia will pull sleep, weight, and steps.
Ovia can push basal body temp, cervical mucus, blood pressure, menstruation, ovulation test result, sexual activity, steps, and weight to Apple Health. Ovia can pull blood pressure data from Apple Health 

Ovia can only pull or push data entered after Fitbit or Apple Health have been synced, so past days’ data will not be synced.
