Hi all.. I have a long term experience of Libre. First of all, the readings that the batches of sensors from last 12 months have been giving are not exact. There is a constant deviation of approx 1-1,5 mmol/l (18-27 mg/dl) compared to the blood.
On the markets there are several 3rd party android apps that offer more exact readings, where Liapp has the best readings according to my experience.
Glimp has also some deviations of approx 10-15 mg/dl, so I presume it's a question of algorithm problems. The big advantage of the Glimp is that the sensors can be read even after the 14 days use.
Glimp people are currently working on an android wear version of the app (smartwatch) which can be used on the Sony Smartwatch 3 (after some tweaking of the watch), which gives you a possibility to use the watch for readings independently of the phone or original reader. I am now testing the alpha version for them and it looks ok, as I prefer to carry as few things as possible with me.
Abbott has previously released the LibreLink app in Sweden, which I am testing and it gives exactly the same readings as the reader itself. Btw, they gave a sensor for free for testing the app. Yesterday I got an email from Abbott saying that the app is now released in Germany as well.
Now, to get to the point, there are several ideas and tries to turn Libre into "CGM light".. I have seen Joern's project as an example. The problem, if you ask me, is that it is all built as a prototype, i.e. the things become bulky when you put something on top of the sensor and then there are issues with fixation, waterproofness, certifications etc. While I honestly don't believe in this kind of homemade solutions, I would like to see Abbott replacing the NFC chip in the sensors with a low energy bluetooth, as the one used in Dexcom sensors, which would "close the loop". As that seems very far away I hope that projects like Joern's and the one on Indiegogo may push them forward.
