(warning: technical discussion ahead)
I use the Libre along with a MiaoMiao (say MeowMeow) to translate the near field communication (NFC) to Bluetooth, which interacts with my iPhone which runs Spike, a program similar to Glimp or XDrip+ for Android. Spike is currently in beta test and under active development. I tried both of the Android programs, too, and used a Sony Smartwatch to translate the NFC to Bluetooth in that case. I also wear a FitBit Versa smartwatch, and my spouse has written a watch face that interfaces with NightScout and shows me my sugar level and trend arrow at a glance, with graphs available at a touch, as well as supporting trend alarms and absolute alarms (high and low) in addition to those on the phone. Simple CGM or Orbits NS are some of his watch faces. This means I don’t need to pull out my phone to know what my sugars are doing, and this has been really convenient for both of us.
Like others, I cover the Libre/MiaoMiao with a Simpatch bandage for several reasons, concealment not being one of them. I am quite active and have sweated off my Omnipods, and several Libres as well, even with additional adhesives. The Simpatch holds the combination together and secures it to me even through active movement. I find, though, that it doesn’t last as long as the sensor, so I replace it around day 7. The MiaoMiao lasts about a month for me before needing to be recharged. Actually it would last longer than that, but I choose to recharge it during the startup time on the 3rd LIbre.
Now, I know that this discussion started about perceptions of medical equipment and the whole cyborg thing. I get that. I also very much understand not wanting to be singled out as being different. Everyone must do what makes them feel most comfortable. I was hesitant to add yet another thing to my body, and carry even more equipment around.
That said, I have found it to be a really positive experience. My current batch of Simpatches are purple, and I also wear my Omnipod on my arm. I have used them as an educational experience when people notice and comment on them. Nearly everyone with whom I have spoken has been impressed, and wanted to tell a friend or relative about such technologies.
I do want to say, though, that I haven’t regretted trying the LIbre. I am astounded at the amount of information I have gathered. I was having both highs and lows that simply weren’t apparent testing “only” 4x daily. Now my spouse can also peek at my sugar levels, and check up on me at night without waking me up to see if I’m still alive. :-/ I can also easily see the mismatch between carb absorption time and insulin effectiveness. Note that these are features of an integrated CGM, and are not specific to Libre. However, I went with Libre because of the longer sensor life and discreet appearance. The phone and watch support came later, and yes, it really helps to have a software engineer in the house. 
I hope some of this helps, and at the very least, lets you know what some options are. This is such a tough disease, and all of use can use some assistance to make the burden a little lighter.
