Sugarmate is a companion app for users of the Dexcom G4/G5/G6 continuous glucose monitoring system. It works great for both the CGM wearer or follower.

Why use Sugarmate with your CGM?

Peace of Mind
- Automatically text message family and friends (with GPS coordinates) when glucose levels get urgently low (Disclaimer: Continued use of GPS running in the background can dramatically decrease battery life)
- Receive a phone call when glucose levels go below normal while you're sleeping (even when your phone is in Do Not Disturb mode)
- Steady Above Normal, Predictive High, and Predictive Low notifications with customizable alert sounds

- Over 30 customizable tiles, including a mini-graph and other stats such as time in range, GMI (& est. A1c), bedtime/wake averages, unicorn counts, % in range/low/high, total insulin, total carbs, and many more
- Daily stats
- Generate and email spreadsheet reports with graphs, stats and all readings, activity and notes

Readings Everywhere

- Today Widget with real time stats and graphs for your lockscreen

Advanced Tracking
- Built-in nutritional food lookup, with voice recognition, food imagery, and barcode scanning
- An infinitely scrolling history of all of your sugar levels and activity. Pinch to zoom, or rotate your phone to enlarge
- Apple Health: two-way syncing, plus automatically creates walk/jog/run events based on your steps

Love it!

I don’t like to ask my independent type 1 diabetic kid if she’s given herself insulin. (She was diagnosed 13 years ago.) With this app, I don’t have to. I can see everything she has input into it. I see an ongoing graph, any activity she has programmed in on the graph (like insulin, activity, food). So now, if I ask, she either didn’t do it or didn’t log it and we can talk about what her numbers did because of that. We have also synced it with her Apple Watch, her phone, my husband’s and my phone, Alexa, and it’s a widget on our phones to see at a glance. She now has 3 apps on her phone. Dexcom G6, with Sugarmate following it, and Dexcom Clarity to send info to the dr. On our phones, we just have SugarMate. There are so many cool tiles to see trending. There are so many options available, I’d like to see if there is a way to walk step by step through the options to see if I’m using them to the best of my ability. (For that matter, I’ve created training manuals with a job before and I’d happily help create a tutorial for it.) The app is so good, the support is so good. The only thing I see missing is getting that info out to the public. People would be flocking to buy it if they realized how good it was!

Dexcom should learn from this app...

This is my first review of ANY tool or software for the iPhone. I am 1 month new to the Dexcom G5 and am sick of the Dexcom support team or lack there of (too many UNDESIRED FEATURES in Dexcom tools and phone only based tech support)! This free tool fills almost every hole left by Dexcom. The only bad comment I can make is it doesn’t use your old Health data so you have to use the tool so long term stats make sense. The free tool has easy to use food (carbs!) look-up that has really helped me level out my undulations....

Heck even the prediction prevented me from spiking low a couple times now (totally missed by Dexcom!)....

This tool is a must **companion tool** for anyone with a Dexcom G5!!! I more often read it instead of the Dexcom app. It is not a HACKER tool to get more battery life or sensor use, but a tool that will help you better use the Dexcom CGM data and help you control your diabetes better than before....

If you use the dexcom app and are debating trying Sugarmate, just look at all these 5 star reviews and do it! Sugarmate is seriously one of the best tools in our diabetes arsenal. It is feature rich, easy and intuitive to use, FREE, has responsive customer service... I could go on and on.
One particular feature that I find especially useful is that as a follower of a dexcom wearer, I can run my finger on the timeline and see the individual blood sugars. In comparison, the dexcom app only allows the original downloader do that and they can only do it when the phone (on iPhone at least) is held in portrait mode. Oh! And they are limited to 24 hours.
We are using the CGM to try and employ Sugar Surfing techniques rather than just passively noting the blood sugar. Sugarmate allows us to better respond to and manage my daughter’s bg. I am seriously so thankful for this app. Thank you!
