Overall, integrating Fitbit with ExpiWell can enrich your research initiatives by providing real-time health and activity data, fostering participant engagement, and enabling in-depth data analysis for valuable research insights.

Additionally, we prioritize protecting participants' privacy, ensuring the security and authenticity of collected data, so we are in adherence with the data security measures of HIPAA and GDPR.


Can Fitbit data be collected continuously throughout the project, even if participants do not respond to surveys?

    • Yes, Fitbit data can be collected daily throughout the project duration, regardless of participants' survey responses. Participants need to reopen the ExpiWell mobile app for data collection. If participants log out of their Fitbit account or experience disconnections, they will receive a prompt to reconnect when they reopen the ExpiWell app.

Does battery-saving mode impact Fitbit's syncing capabilities?

    • No, battery-saving mode does not disrupt Fitbit syncing if data is already synced with Fitbit, as we fetch data directly from the Fitbit API.

Is it possible to collect Fitbit data passively without opening the ExpiWell mobile app?

    • No, passive data collection without app interaction is not feasible because the Fitbit APIs we use for data collection require app interaction.

What happens if a participant forgets to open their ExpiWell mobile app?

    • Upon reopening the app, you can still collect data from previous days. For example, if a participant misses days 2 and 3 but opens the app on day 4, data for days 2, 3, and 4 can be downloaded.

Which variables are affected if Fitbit is not worn during a sleep period?

    • If Fitbit is not worn during sleep, variables like HRV, Breathing Rate, Sleep, and Heart Rate Time Series data will be empty because Fitbit requires a minimum 3-hour sleep period to track these metrics.

Can HRV data be collected during the workday (e.g., early morning, midday, early afternoon, and late afternoon)?

    • Based on Fitbit's documentation, HRV data collection is dependent on at least 3 hours of sleep, making it unavailable during the workday.
