Sharer’s receiver and transmitter, smart device and smart watch
Dexcom Share consists of the following components:
Dexcom G4 PLATINUM System, including the Dexcom G4
PLATINUM Receiver with Share, the Sharer’s smart device,
with the Dexcom Share2 app installed, the Internet, and
the Follower’s smart device with the Dexcom Follow app
installed.
Smart watches can be used as a secondary display for
either app. See dexcom.com/share2-compatibility for smart
devices and smart watches that work with the system.

19Learning About Dexcom Share
When the Sharer’s receiver has Share “On,” the receiver
transfers glucose information using Bluetooth wireless
technology to the Sharer’s smart device. The information
then is sent to the Dexcom Share Cloud using either Wi-Fi
or a cellular data plan. Lastly, the glucose information is
sent from the Dexcom Share Cloud to the Follower’s smart
device using Wi-Fi or the Follower’s cellular data plan.
Below is how Dexcom Share2 and Dexcom Follow apps
work with having the Dexcom Follower using a smart
watch:

20 Learning About Dexcom Share
The Sharer must have their smart device within Bluetooth
range of their receiver in order to send data to their Follower
or the system will not work.
For smart watch users, it is a secondary display, meaning
the watch will only work if used with a smart device.
Changing device settings on either the smart device or
smart watch may affect settings on the other.
