Yes! You may connect as many fitness and health devices as you like. You may also choose which activity trackers show which metrics on your metric page. On top of that, you can take advantage of our manual log.
If you would like to remove one of your devices, simply click on Disconnect button on your Devices page.
Important: please note that there can be only one data source for each metric at at a time.
When you change your data source, there is a chance that your new device will overwrite the previous device's (data source) data.
For example, if you connect a Fitbit/Withings/Misfit/Xiaomi/TomTom/etc. and if you have data on that device it, once connected, it will overwrite your last 7-day data.
