I wanted to export Fitbit heart rate for research purposes however they provide a day's summary only. By chance I found a company who made a program to access and export ALL data even every second sensed. Kindly the developer modified it to add more features to populate with intervals or sampling options for me. These data are very useful for those who suffers health problems and researchers like me. I tried several versions with the developer and he finally released it to help others. It is free fir now however he owns a software company. thus it may become a commercial product in future. (This is first time for me to post and my apologies for any mistakes. )
