I'm not sure if Dexcom's app works well with screen reading software but it is helpful to my visually impaired family member. It gives continuous monitoring!

I used the freestyle libre. It is totally accessible for blind people. There is the sensor part and the reader part. Don't get the reader, it's useless and inaccessible. It doesn't matter because you can use the app. If you use the app, freestyle libre is totally accessible. You can insert the sensor yourself. Tap your phone on the sensor when it is unlocked to do a reading. You can read the reading with the screen-reader on your phone. The only thing you will not see are the graphs and the glucose trend, but I was good just with the reading.

Then, I switched to Dexcom G6 for health insurance reasons. In terms of features, I prefer the dexcom. You don't need to scan the sensor, it updates automatically. In the app, you can read your glucose level and the trend as well. It will say something like "102 and slowly rising". However, you cannot insert the sensor by yourself. This is because they need you to enter a code for every sensor (and you need to do that every 10 days). Let me explain more how it works. That said, Dexcom G6 has alarms which are a blessing. You do need to calibrate it from time to time though, especially on a new sensor, so I would recommend getting a talking finger prick.

First, you need to pair a transmitter. This transmitter has a code on the box. You cannot see that obviously. You need to enter it in the app, either by scanning it with the camera or entering the PIN manually. I can tell you to forget scanning with the camera right there. You need to align perfectly a small overlay with the code. There is no way you will ever succeed if you can't see. Even someone sighted has trouble, you need to be at the right distance with the right framing and it is extremely tight. Plus, you have time to do it or it times out and you need to start over. The best bet is for you to ask someone what is the code and enter it.

Once the transmitter is paired, you need to add the code of the sensor. This one, I found that you can use something like Google lookout (or I guess Seeing AI on iOS) to have it read the code. The code is located on the adhesive protecting part of the sensor applicator. Someone can show you where. Just have google lookout tell you the 4 digit number and type it in the app. Once that is done and you insert the sensor, you are good for 10 days, after which you will have to repeat the sensor process again. However, the transmitter is good for 90 days, so I find it convenient enough where I need to ask someone every 3 months to tell me the code of the transmitter.

On a side note, I still find it extremely stupid for a company that sell CGM for a disease that notoriously make people go blind to not make the process of using their product accessible. Just for the autonomy and independence I preferred Freestyle Libre, but it didn't have alarms which you honestly need. The Freestyle Libre 2 has alarms, but I haven't tested it out, so I don't know if the process is the same as the first one and is accessible. I'm wondering especially for the transmitter part.

Up here in Canada, I have clients who use Oracle.
