Fitbit vs. Withings

Which device to measure activity is right for your study?


Fitbit

Withings

Pros

  • Can collect intraday data (minute by minute data)

  • W2H can calculate a daily MVPA (moderate to vigorous physical activity) value for participants

  • Data connection with W2H is seasmless

  • Collect data on an hourly basis

  • Store data on device for up to 30 days

  • Can collect intraday data (minute by minute data)

  • Charge lasts about a year (on certain devices)

  • Sleeker look (looks just like a watch)

  • Store data on device for up to 11 days

Cons

  • Charge on device required every 3-4 days

  • Data returns a 0 value if participant does not sync instead of marking the event as "Skipped"

  • Data connection with W2H has caused support 

    • Participants will sync and data does not get to W2H on time

    • Mostly an issue for studies giving daily feedback, not necessarily a hindrance for studies collecting passive data

  • Currently no MVPA calculation
