Choosing a Dexcom G6 / xDrip+ compatible watch in September 2020

First post - my apologies if this has been covered elsewhere.

My T1D son (9yo) is about to go onto the Dexcom G6, with a Tandem x:slim2 pump coming later this year.

He’s currently running a Freestyle Libre with pen injections - so it’s going to be a big step forwards.

Like many parents I’m looking at connecting the G6 directly to an Android smartwatch so he doesn’t have to carry a phone at all times.

I’ve been reading about xDrip+ - but wanted to sanity check before I splurge on a smartwatch.

The xDrip+ documentation (https://github.com/NightscoutFoundation/xDrip/blob/master/Documentation/WatchGuide.md) shows the following watches as being compatible with xDrip+:

Watch Watch OS?
Sony Smartwatch 3 (SWR50) WearOS 1.6
Asus Zenwatch 2 WearOS 2
Asus Zenwatch 3 WearOS 2
Huawei Watch WearOS 2
Huawei Watch 2 WearOS 2
LG G Watch WearOS 2
Polar M600 WearOS 2

But these are all older models & not available off the shelf/ in-store in September 2020.

From my understanding I can only use these watches with xDrip+ as they all (apart from the Sony) require a firmware update.

Or is it possible to use any WearOS watch - but that might cause a hit on update time/ reliability?

Has anyone got any recommendations for a newer (2020) smartwatch they’ve connected directly to the Dexcom G6 via xDrip+?

I should mention we live in New Zealand. We generally have good access to tech for the Asian brands (Samsung, LG, Huawei etc.) & Apple - but it’s harder to source tech focused on the US market (i.e. Palm).

The other thing I wanted to check is the xDrip+ documentation only talks about the Dexcom G5 - is connecting the Dexcom G6 any different?

I appreciate any help - or links if these questions have been answered elsewhere.


Hi @Tama and welcome! @docslotnick is one of our resident XDrip experts and will most likely be along shortly. The info on GitHub is slightly dated as several of those watches don’t need firmware updates and there are other watches that work. That said however, it sounds like you actually want a watch that will work as a stand alone unit (without being tethered to a phone). If memory serves there are very few that will accomplish this task - the only one. I can think of is the Sony SW3. I might be very wrong and @docslotnick will definitely have a currently curated list for you, or can point you in the right direction.


Thank you for the welcome @elver

Yes, that is exactly what we’re after.

Hopefully there are more options than the Sony SWR50 as it’s a 6 year old model & really hard to get hold of in New Zealand. From what I can see my only options are refurbished models through Amazon etc. - which cost more than a new 2020 smartwatch!

Hopefully @docslotnick can give me some more watch options.


There are many other parents on this blog in the same situation… maybe they would have valuable inputs also.

Hi @Tama. Welcome to FUD.

You can try a rather inexpensive watch developed by the developer of xDrip+ that certainly works


Another option is the Finow Pro watch, which is basically an Android 6 on your wrist, but smaller. That way you could have the follow functions that are built into xDrip+.

Hope this helps.


We are currently using Apple, and have been disappointed in the vaporware that is an Apple watch that can directly connect to the Dexcom G6. With that being said, your son will soon be at an age where the phone never leaves his hands, and so a phone that updates a watch becomes a reasonable compromise.

My son (17) uses the G6 and Tandem pump combo, and it is really awesome. You will really enjoy the Control IQ algorithm, although it will struggle to help during all the growth periods that are coming shortly.


Thank you, that looks perfect. I just ordered one to check it out.

I’m surprised it’s not mentioned in the xDrip+ documentation - it looks very fit for purpose.


I am using a samsung galaxy watch, and have a samsung phone. The watch will act as a receiver, and works well with xdrip. I not sure you can be totally phone free however.
A benefit is that you can set up watch maker app and load a face that shows BG, rate change, and amount of change over time. Some will change color of part of the face with BG levels.
I’ll try to post an example of one I created.

Hello Mike,
I have a Samsung S9 phone and I am using the Tandem x2 pump with dexcom g6. I am looking for a watch that is easy to set up and get a watch face that will give me my numbers on my wrist. I see you are using a Samsung watch which model have you found that works best for you? Thanks for any advice. I used an old Pebble, but it has quit working and is outdated. Thanks, Kelly

I have two watches, a Samsung Galaxy and a FitBit Ionic. Both should work with your phone. The newer versions of both watches will work with the various watch faces I use. As for the easiest, I would suggest the FitBit. There are several watch faces that were created for the FitBit that work very well, and someone has created an exercise app that records your workout while showing your CGM values. Note, for both watches you have to use xdrip to transmit the data (simplistic answer), and you can see the graph of the data…
The watch faces for the FitBit are downloaded via the dashboard on your phone. You then set up the permissions and alarm limits before transmitting to your watch.
There are also watch faces for the Galaxy. It is a bigger and heavier watch - but the newer versions are smaller and lighter. In order for the watch face to work you have to download several apps and run an install app, and someone has done a lot of work to get it working; then all you have to do is put in the alarms and etc. So much more complicated, but it is more customizable. I adapted a couple different watch faces to make one that worked best for me (less clutter). One irritation with the galaxy, there is a lag in the most recent data being updated on the watch face. I like playing with the Galaxy and programing various features, such as having a graphic change color with the blood sugar.
The two watches use different operating systems, so you cannot use a watch face from one on the other. IMO the fitness data is presented in the dashboard of the fitBit. One other note, and I was surprised that xdrip has this feature, your heart rate and steps/activity are shown in the xdrip+ app.
The only issue with the FitBits is a random reliabiliity failure.

I hope this helps.
