Sync Your Fitbit Device With Cronometer
updated june 2023
New: Sleep Stage Data Now Available
Many of our users know that we’ve been supporting a Fitbit integration for a long time now – almost a decade! Fitbit supporters have long had the option to import their weight, body fat percentage, sleep, activity, heart rate and to export their food calories data.
In our latest app update, we’ve introduced support for seeing time data on sleep stages, so you will now see the time you spent in REM, light and deep sleep within the imported diary entry.
If you’re interested in having sleep import into your Cronometer account and already have your Fitbit device connected, head to your Settings > Connect Apps & Devices >Devices and click on Fitbit to select your desired metrics.
