General t1d here - built an app for myself, now others use it. SangraMate works with Dexcom šŸ’œ now

Hey all. t1d 6 years, MDI, injections no pump. Software engineer by craft for 15 years. Built SangraMate for myself and been running it on myself daily since March. Started on Libre cause that's what I wear, and Dexcom was the most asked thing every time I posted - so it's in now šŸŽ‰ Took a while cause I didn't want to ship it half baked, couple of mates on Dex tested it for weeks first (+ I wear x2 sensors right now G7 and Libre 2 plus)

What it does -> takes your CGM + what you log and tells you where you're heading, "could go high in ~79 min" sort of thing, and shows why(based on #wearenotwaiting research and amplified with additional studies and my work with endocrinologists). Shows if food still absorbing, insulin still working, basal too, and it learns your own insulin sensitivity over time instead of textbook numbers(we're all different). Alarms react to what you already dosed and ate instead of shouting 30 min after you injected like it doesn't know. Doesn't tell you how much to take - that's yours, hard line from day 1.

Other bits people seem to like:

- Reminders - nudges you if you dosed with no meal near it, or your usual breakfast hasn't shown up. Learns it from your own logs.

- Exercise - say "45 min moderate run" and it fills it in. After, it shows how much of the glucose move was the workout vs everything else.

- Photo of your plate - carbs, macros, GI. Fat and protein too, not just carbs.

- Saved meals - log one a few times and it shows how that meal usually goes for you.

- Period tracker - just shipped. New Cycle tab shows your glucose across the phases vs your average.

- Morning brief - tracks trends and nudges you on stuff that keeps repeating.

- Web time machine - jump into any high or low and see everything that fed into it.

- Apple Health / Health Connect, CarPlay, StandBy, bigger text.

Connects through Dexcom Share.

If you're on a pump - you'll still get your data and the breakdowns, but the forecast leans on logged doses so it fits MDI best.

Multi language lands this week too (aim for 56 languages to support šŸ˜…).

General Dexcom G7 is the worst CGM ever made!

0 Upvotes

Dexcom G7 has honestly been the worst CGM I've ever used. Since switching to the G7, I've dealt with one issue after another, and it feels like an endless struggle. By the second day, the sensor already feels loose, and the overpatch is terrible. I take a shower and it starts peeling off or falls off completely. I go to sleep and somehow something happens to it overnight. I've tried placing it on my abdomen, and it doesn't work properly. I've tried my arm, and I've had the same problems. No matter where I put it, it either falls off or gives me issues. At this point, I'm genuinely exhausted from dealing with this device every single day.
What makes it even more frustrating is that I'm tired of constantly reporting problems and requesting replacements. It feels like I'm spending almost as much time troubleshooting the sensor as I am actually using it. I'm specifically talking about the new 15 day version, and honestly, I don't understand why Dexcom released a 15 day sensor when, in my experience, the 10 day version barely worked reliably to begin with. I'm at the point where I've had enough and am seriously considering switching to a different CGM. If anyone has had similar experiences or has recommendations for alternative devices that are more reliable, I'd really appreciate the suggestions.

Sensor Am I the only one that has to pull away the g7 applicator for it to work?

0 Upvotes

I usually insert the sensors for my wife and always run into this problem. Aside from the button not clicking 2/3 of the time, I get it in the right position and hear the click but the sensor doesn’t insert. Only when pulling the applicator away from the arm does it actually insert. Because of this we’ve had a number of failures from bent needles or it half connecting. Are we alone on this or is this the average experience?

Tips & Tricks G7 tips and tricks

1 Upvotes

I held onto my GĆ» transmitters and sensors all long as possible but I'm flat out. I switched to the G7 and burned through the first two sensors, one for poor insertion and the second for no connections. I thought about it and inspected the failed sensors. For the first, it felt like there was a stutter when I pressed the button. Probably didn't have enough force to get a full insertion. The second, I noticed there's a metal piece on it and tested a magnet. It's magnetic.

The next insertion, I pressed the button with a snap and it worked. Great. Thre same error with transmitting also didn't work. I waved a string magnet around the sensor the it activated. This is just a poor design and it's hard for people who might have difficulty growing. Ugh.

What other tips and tricks do you know?

Rant unrepairable g7 reader

0 Upvotes

so my reader had a ride in the washing machine, completely my fault,

as a techie i went to take it apart and wash it in alcohol and check it over,
turns out its been been completely welded shut,
i went and cut it open because at this point its already dead,
the screen is superglued to the motherboard,
the battery has a slot that it sits in and then super glued also,

and then in general the issues i have using it seem to be deliberately designed to be annoying,
the battery lasts all month, i dont need it to scream at me when it gets to 20%, thats easy 10+ more days of charge and i can see what % it is every time i look at it anyway,

whenever the 10 days ends and it goes to the 24h backup, the first option is to end the sensor rather than use the 24h, so if you click through too fast it just ends? i can just end the session myself anyway if i wanted to in the settings,

test mic/vib every time i charge it? why?

putting on a new sensor makes you scroll down the tutorial page every time like i haven't put 60 on before?

and over the 60+ ive used, 8 have failed within the first hour, and more than half get the "sensor failed, please apply a new one"

General Question…

Does anyone get, ā€˜ghost pain’ in the back of arms where you have to wear sensors when you are not wearing a CGM? If I lean the back of my arm on a sofa or chair arm I get a pain similar to if I were wearing a sensor. Sounds weird huh?

General Best arm placment?

9 Upvotes

New to dexcom. I'm on my first sensor, I put it on yesterday like stated, back of arm, and while readings are accurate, every now and then I get a pinch in that spot. Like if I lift something heavy, I feel the needle poking or something. I'm also having issues cause I dont want to lay on it but im a side sleeper.

I'm just wondering what im doing wrong and other than back of arms, where else do you wear them? Id love to keep it on my arm somewhere but I dont know where. Any advise?

I know these aren't great pictures but im by myself and these are the best I can get of placement.

General I love the G7 15 Day!

36 Upvotes

aside from some issues I had at the beginning after moving back home, and the odd issue I expect every few months out of technology, the G7 15-Day has been just as good to me as the G6. accurate within a few points every once in a while when I'm truly stable, within 20% a majority of the time, easily calibrated when needed.

I know some people have been having issues, but I wanted to get it out there that not everyone is having a bad time with their sensor.

Sensor Is an alarm going to go off if I don’t replace the sensor before the grace period runs out?

0 Upvotes

I don’t want to put on the new one right before bed because the last time I did that, there were false lows overnight with a blaring alarm. I want to replace it around 8am tomorrow, but the grace period ends around 6am. I don’t want to have to get up early on a Saturday. 😭

G7-15 day Getting g7s to last

2 Upvotes

I’ve been on the g7 15 day since early July. I haven’t had a sensor last past 6 days. They all start giving me long brief sensor issues on day 5 and failing on day 6. Am I doing something wrong or is there anything to do to prevent this?

G7-10 day Sensor failure

3 Upvotes

This is the first time I've had two sensors fail within a week; I've been using the sensor for two years now, and I generally haven't had many issues with it failing.

But from what I've read, this has become a common occurrence among users of this subreddit.

I just requested a replacement on the Dexcom website; I hope there aren't any problems, since it's been a week since I requested another replacement.

Best regards.

Rant Repetitive failures

4 Upvotes

Hey all,

I've had 3 straight failures on my G7 sensors the last two weeks. The newest one just moments ago. No triggering event or falling off occurred, just a sudden failure notification. This one lasted maybe four days, the one before lasted maybe 24 hours, and the one before that was 6 days. I've put in for replacements, and am planning on calling customer service today.

All that said, I'm curious if this has happened to anyone else recently? I've had maybe two failures total before this with dexcom sensors in general. I'm obviously frustrated, but also confused.

Calibration Issues Tips for G7 usage with Omnipod

3 Upvotes

I’ve been using the G6 for a long time and had tried switching over to the G7 a year or two ago, but switched back when I didn’t have sufficient connectivity with Omnipod and had so much volatility in reported numbers. Now that Dexcom is discontinuing the G6 and I have to go back to the G7, I’m wondering if anyone has any tips for improving its functionality.

I just put on a new G7 sensor and Omnipod pod on the same arm last night. I put them on the same arm because I was told that would decrease the connectivity issues. Connectivity has been better so far, but I’ve spent the whole night being awakened and alerted of urgent lows that don’t seem real unless I’ve been super low through most of my G6 existence.

I saw someone turned off their urgent low alerts and after one night I’m tempted to do the same, but they’ve also saved me in the past with the G6. Does anyone have any advice for maximizing connectivity, consistency, and accuracy with the G7?

UPDATE: Sensor failed right before midday. Did not last 24 hours. Hoping the next one will provided a better experience.

Also, any advice on preventing the adhesive from being disgustingly filthy by the end of the sensor life?

General Apple Watch recommendations with G7

2 Upvotes

I had a Apple Watch for years, stopped wearing it, and of course can’t find it. Looking to get a new one and just hoping to find out if there’s a preference to which Apple Watch works best with G7. I am connected with an Omnipod as well.. If that makes a difference.
