Hello fellow Dexcom users!
If any of you use Mac, you're probably terribly annoyed that dexcom studio software works only on Windows, so there's no simple way of downloading your data from Dexcom receiver. I don't know if anyone heard of it yet, but today I found TWO (yes, TWO!) solutions for this problem! Both allow you to view some charts and download your readings in CSV format.
1) Google chrome extension by Nightscout - works on Windows, Mac OS and Linux, requires Chrome browser: https://chrome.google.com/webstore/detail/nightscoutinfo-cgm-utilit/ffjaahelelfakhdpphligimoibajjlhl
This is an extension for Chrome browser made by the same people that are working on Nightscout project (CGM in the Cloud). As the author says: it is NOT offical Dexcom software, and may not work at all. So far for me works great
(I compared last 30 days of readings with the ones downloaded via Dexcom Studio and they matched nicely).
Pros:
- download directly from your browser, click-click and you have all your numbers in. Install the extension, plug your receiver into your computer and ta-dah!
- simple, fast and easy
- gives you readings in mmol/l
Cons:
- exported readings are rounded/cut to 1st decimal (a little annoying if you're comparing the numbers with export from Dexcom software, as it gives you 2 decimals), but not a big issue
- graphs are very simplistic, but still give you all the data you may need
- as author says - it's not an official software, so the data MAY be completely wrong (I didn't find any issues so far).
2) Windows/Mac: Dexcom portrait software: it's basically a simpler version of Dexcom studio in your browser: http://www.dexcom.com/portrait
Simpler version of the Studio software that works in your browser. Installs some kind of plugins to your browser and you can upload your readings directly to the software.
Pros:
- official Dexcom software (so you can rely on it being correct)
- gives you similar "dashboard" as dexcom studio - if you're interested in that
Cons:
- you need a Dexcom online account (officially only available in US),
- gives readings in mg/dl (no option to change it)
- so far I only found the main graph with patterns...?
- it uploads your data god-knows-where... (if you're worried about this kind of things).
I tried both solutions. I must say Nightscout's Chrome extension is awesome and simple - seems like much less hassle that the Portrait software - but I ONLY need a CSV export of my data. On the other hand, I already went through the hassle of creating a dexcom account, so I may stick with the Portrait for now - simply because as it's an "official" app, it should give me a peace of mind that my exports are correct. Probably until it annoys me enough to quit using it
Hope this helps anyone who's been struggling with downloading Dexcom readings on a non-windows machine!
