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!

I’d give it 10 stars if I could. Favorite T1D app⭐️⭐️⭐️⭐️⭐️⭐️⭐️

We have used Sugarmate for several years now for our child. We have several devices and apps that we use to manage his blood sugar. (Omnipod, Dexcom, Loop, NightScout, Dexcom clarity, Dexcom follow + many more we’ve tried) and I always end up referring back to sugarmate. I like the interface, I like the flexibility, I like the ease. We use it on our watches, in our cars on via Apple CarPlay. We use the alarms and the urgent low phone call is amazing. I think this app would also be extremely beneficial to someone who is using injections instead of pumping, because you can easily track injections, carbs, activity, anything at all. SO customizable. You can even search nutrition info. The responsive of the developer on several occasions (haven’t had app problems in quite a while) was terrific as well. He helped us troubleshoot in a very timely and personal manner. CANNOT give enough stars or say enough nice things to describe sugarmate. ⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️

Update to: Used to be amazing now it has glitches

Update: the developer got with me and with a few troubleshooting steps I completely overlooked the app is functioning as it should. It was a malfunction on my call screening services side. I’m back to getting low calls and am loving the app. I am so thankful not only for this app but for the developers that they read the reviews a d offer to help when users have issues. Can’t recommend enough!!!! The app over all is very good, but within the last two weeks it has started going straight to voicemail when calling to alert me of my lows. This entirely defeats the point of why I have this app. All other calls come through with no problems, no do not disturb or silent features are turned on. I’ve even added this number as a favorite and deleted and downloaded the app again. Hopefully they update the app and it gets fixed as I experience lows regularly and really need this feature to work.
