Dexcom Share: Product Review

Unpacking the Dexcom share reminded me of the same level of excitement that I had when I got most of the Apple devices: a clean experience that builds anticipation and contributes to a continued positive experience.

Let me proceed my comment by indicating that my experience with my Dexcom CGM is unlike any other I have had with any othe diabetes device in my life, including my insulin pumps (I have been on two in the past decade) and a variety of glucose meters I have used since 2002. I have lost track of the number of times my Dexcom has saved my life: being awaken by or alerting my wife of a dangerously low blood sugar has literally averted disaster on countless occasions.

So naturally I was very happy when I heard that the Dexcom Share had been given the green light by FDA in the US. This setup consists of:

  • A docking station that charges your Dexcom G4 while it connects via Bluetooth with your iOS device (an Android version is in the works, as I understand).
  • The Dexcom Share app that allows you to pair your Dexcom receiver with a Dexcom account “in the cloud” so your data can be shared with those you want to. This app is available through the Apple App Store.
  • The Dexcom Follow app that allows those whom you want to share your Dexcom’s 24-hr window of data along with a few alerts for lows or highs, to Se the data. This app too is available through the App Store.

Getting up and running is quite straightforward (it took me no more than 10 minutes or so), and I felt the process should be fairly intuitive for anyone that has paired Bluetooth devices or paired remotes to receivers. Here’s how I found the experience with each of the pieces of the setup.

THE DOCK

I found the design sleek, though perhaps a bit bulky. You can have it standing up or sideways (with convenient anti-slippery things below) to fit different spaces on your night table.

The principle that it belongs on the night table is an interesting one because it is mostly set up to be parked somewhere, since it has to be plugged to a power source to work. My friend Kelly and her crew made me realize that you could take the Share on the road as long as you can plug it to a portable USB power source, like a Mophie, but that is more of a hack (it’s fairly bulky of a combo) than the way the product appears to be designed for.

The only annoying thing about the dock was the brightness of the LEDs (a green one indicating power, and a blue one indicating Bluetooth connection, which was VERY bright at night). I may end up putting an opaque tape on top of them, because otherwise there is no way to have the Dexcom screen facing you without being “blinded” by the intensity of the LEDs. Well, maybe not blinded, but they are very bright indeed!

THE DEXCOM SHARE APP

As soon as I fired up the Share app (as instructed in the quick setup instructions in the inside cover of the box), I was greeted by GlucoMonster. Although admittedly cute, I couldn’t help but being immediately reminded of the monsters from MySugr, plus the plushy character (whose role is to signal of there are connectivity problems with your Dexcom via the Share dock) doesn’t really resonate strongly with the Dexcom brand for me. Don’t ask me why: I would honestly do away with the little fellow (nothing personal, dude!)

Getting the serial number typed in to pair the app to the receiver proved to be challenging in two ways:

  1. I forgot to write it down (as instructed on the same instructions) before plugging the Dexcom to the dock. I ended up pulling it out and taking a picture of it. It may be a nice (though tiny) future improvement to move the serial number sticker to the opposite side of the receiver so it sticks out visibly outside the dock when the receiver is in it.
  2. After routine use (wear and tear) after years, the sticker can be hard to read. Maybe the app could sense any nearby Dexcom receivers/docks, similarly to how you pair Bluetooth devices?

After the S/N was in, it was very straightforward to complete the process, but I admit that I was missing being able to SEE the CGM data within the same app. I gave up, realizing the Share app was designed to do just that: share the data. So I downloaded the Dexcom Follow app, to get a feel for it, and see that part of the experience too. But not without first inviting my wife to follow my numbers through it too.

THE DEXCOM FOLLOW APP

The experience my wife had with the email she received inviting her to follow me was clean and straightforward: I picture this will be the experience of most people that get this invitation.

The invitation message lto a new follower looks very straightforward.

I fully anticipate the need to make the invitation process a bit more sophisticated in the not too distant future, as people change phones, delete apps, etc. which hopefully won’t mean that they need to create a new Dexcom user account to follow someone else every time they change iOS devices. Yet, any observations to improve the user experience and the setup flow PALE when compared to my wife’s joy over being able to see my glucose data remotely. I travel a lot for work, and this is something that has always worried her.

I eventually set up my own Dexcom Follow app, to be able to view my own numbers on my phone: it honestly felt odd, and I would definitely envision a more integrated experience for people whose phones are both sharing and following their own data. Or maybe it’s not a frequent use case, but to me that flow in the experience felt a bit odd.

Now that my wife and I are both setup to see my CGM readings for the past 24 hours, we are VERY happy!!
