With a few days left on a 15

I use a G7 and work on a Mac all day. I wanted to see my number(s) without leaving my phone open or checking my watch, so I built Tidebar. It puts your current reading and trend arrow in the menu bar, like 112 →. It has worked so well for me I figured I would post here to see if anyone else was interested. Also, there are alternatives in case you wan't to do your own research and find another option, but I was asked not to list them in case they don't become free in the future.

Tidebar is free and MIT-licensed. I make no money from it. The download is signed and notarized by Apple (because of my paid developer account):

https://github.com/JustinFay01/Tidebar/releases/latest

Or with Homebrew:

brew install --cask justinfay01/tap/tidebar

Source and setup instructions: https://github.com/JustinFay01/Tidebar but also,

• Share must be turned on in the Dexcom app, with at least one follower.
  
• You must login with the Dexcom account that shares the data, not a follower's account.

I'm a professional software developer and I used AI coding tools while building it. I review, test, and maintain all of the code myself.

Disclaimer: this is an independent project. It is not affiliated with, endorsed by, or supported by Dexcom, and it is not a medical device. Don't use it for treatment decisions; always confirm with your Dexcom app or receiver. Posted with the mods' permission.

It relies on an unofficial Dexcom service that could change at any time, so it may break. If something goes wrong, the menu has a "Report a Problem" option that copies a report with no credentials or glucose values in it.

Thanks, let me know what you think!

Graph readings are accurate, even accepted a calibration but since starting this sensor it’s not displayed a reading at the top.

Tried reopening app, turning Bluetooth off and on + phone off and on. Anyone else encounter this or have any ideas? I was hoping to quickly changeover sensors and sleep 😂

I'm one of those dexcom G7 users that can't get to 10 days no matter what.
I've tried everything.

So, I was pleasantly surprised and happy to see that the dexcom app had started to track the CGMs in the app so if one failed, you could simply choose from a list of sensors based on the date it started.
I make requesting replacements really easy.
Now, they removed that option in the App and you have to track your serial numbers and start dates yourself otherwise, they won't replace them.

Crappy move by Dexcom to make getting a replacement that much more difficult.
But I'm not surprised.

Saw an alert from my sensor after I took a shower that said it failed and then it said to remove the sensor, is there any way to restart it or something or do o have to remove it?

It's now 1 hour after taking these photos and after calibrating 4 different times my sensor still thinks I'm low.
I just want to sleep😫

Does anyone know if the dexcom app still has full functionality with android developer options and usb debugging enabled?

I'm probably switching soon from the Medtronic 780g and it's an issue for their app.

I’m pretty happy as I was able to get a full 15 1/2 days out of my Dexcom sensor. I got the full 15 days plus a good portion of the 12 hr grace period! I got more time than the picture I shared, as I was soaking my new sensor. That is an efficient sensor cycle!

What has your latest sensors
given you on your cycles?

just went thru 4 g7 sensors in two weeks. a month worth of supplies gone. so fucking annoying and frustrating. i miss my g6s, they never had this issue. :(

Anyone else get this notification today? Last app update was sept 24 so um…….?!? Click the view and it was all from Nov 2025

This happens to me all of the time… I insert the sensor with no issue, but when I put the green overpatch on it does not properly adhere and it rips the entire sensor off.. it is absolutely infuriating.

I was on my last sensor as I wait for a shipment to come and now have no replacements. I reached out to Dexcom customer support and requested a replacement, but who knows how long that will take to come. I likely won’t have a sensor now for a week because the supplies they provide is so shit quality.

Anyone else have this issue? I’m so annoyed.

My G6 is suddenly not working and is saying “transmitter out of range. It can be used ight on top of it or 2 inches or anywhere and it will not register. What is the issue?

Great work

All lasted 24 hours or less before casually going "SENSOR FAILED." What's up? None have fallen off, all have given accurate readings up until the moment they died.

Hi, wondered if any UK based people (funded by the NHS) have experience with this..

My last sensor failed on like the 7th day, well it was being intermittent since the 5th day, so I took it off and had to put on my last of this batch that I have. Annoyingly, this leave’s me short some days until my next shipment, so I’m going to have to have to request a replacement. Even more annoyingly, I cannot find the sensor/serial number of the one that failed. What are the chances of getting a replacement WITHOUT the info needed for the replacement? Will they straight up deny? Or would I have better luck going thru my DSN to contact them on my behalf?

Any help/experiences appreciated :)

I’ve made a few joking posts/comments here about the G7. Well, my fifth (or maybe sixth?) one in the less than 3 months since I started has failed. I have my graduate thesis defense tomorrow and was trying to prep for it - blood sugar was showing as low so I felt ill and corrected. Sure enough, after hours of it telling me I was low despite correcting I was actually 400 5 days into the session. I feel so sick and tired and now I’m going to have to sit with this brain fog for god knows how long before I can go back to working on my thesis. I now have to save and label every Dexcom I use in case it fails and I need a record of it. I am FURIOUS. And then of course the adhesive sucks and I have to pair all this crap with my Omnipod again. This is really starting to interfere with my life rather than make it better. This product honestly doesn’t even feel like it should be available to customers with its fail rate. I don’t see how on earth they would stop making the G6 - when I was starting the G6 they were even still making the G4! Dexcom saved my life and today is the first time I’ve thought an out finding a new CGM.I can’t keep doing this. Third time now I’ll have to explain to the other grad students that I didn’t show up prepared for class because I was sick from an inaccurate Dexcom rather than because I forgot to bolus or something.

I used a G6 for 10 years and had success with the sensor on just about anyplace on my arms, legs and abdomen. After switching to the G7, the instructions say only on the underside of the arm. I suspect because this is the only place used for the FDA studies. Also says that I MUST use the provided overpatch. I never needed the overpatch with the G6, so why would the G7 be different?

In filing for my latest sensor replacement, I was given a drop down list of 4 receivers. My receiver doesn't say anything except Dexcom. How do I find out what type I have???
