You CANNOT get Xdrip+ on the play store because it violates Google’s terms of service. I suspect because they’ve plagiarized elements of the original software the various sensor manufacturers have put out, but I don’t know that for sure. (As in, taking bits of Dexcom’s original G6 app, especially the communication protocols, and copy/pasting it right into the Xdrip+ app, then doing the same with all the other sensors too.)
Instead, you have to go to a website called GitHub, which is a very popular website for hosting safe software, download it, then install it yourself through a process called “sideloading” an app. The exact process depends on your tablet and what version of Android it’s running, but it’s not difficult.
If you’re lucky, this is the easiest way:
Go to this website: Releases · NightscoutFoundation/xDrip · GitHub
There is a new version of Xdrip released very often with minor improvements, called a “nightly build”. You want to download the most recent one, which will be at the very top of the page. As I’m typing this, that would be “Nightly Build 14 Jan 2022”. Click on the word “assets” right underneath that. That will expand, and show you that they’ve published 3 different files today. You only need to download the one that ends in .apk. Click on “xDrip-plus-20220114-73ada42.apk”, and it should automatically start downloading. If it doesn’t, you may need to do a long press and wait for a pop-up, then click the option in the pop-up to download the file. If at any point your are asked if you want to download or proceed, you do.
If it is downloading, there should be a new notification for it up in the notification panel at the top of your screen, showing the download progress. It may take a little while, depending on how fast your internet is. After the download is finished, hopefully you can click on the “download finished” notification (the wording may be different, like the filename followed by the word finished). It should ask you if you want to install the file, to which you confirm. It will then probably give you some sort of warning about the danger of installing from unknown sources and ask if you want to proceed anyway, which you do.
If you’re lucky, that will have adjusted the necessary settings for you and installed Xdrip+. You should see it at the bottom of the panel where you find all your apps.
If you’re not so lucky, depending on your device, you may have to enable the " install from unknown sources" setting yourself, and then go find the file you downloaded. In the most recent versions of Android you actually have to give that permission specifically to your web browser, so the location of that setting has moved. If my previous download solution doesn’t work for you, tell me what tablet you’re using and what version of Android it’s running, and I can help you further.
