Fitbit vs. 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
