I had two fail last night. One the needle fell out on attaching to my arm, the other stuck to my arm but simply wouldn't connect to my phone. I rebooted my phone several times but no joy.
I've requested replacements, and have contacted Dexcom for the free trial. In the meantime I'm back to...
I was trying to find Juggluco in the Playstore but Juggluco's own site says they've been banned from the Playstore and I must download from their site.
Tad iffy about that but I'll read the data and see which watch they say to get while I have a think.
