    I inserted a new Freestyle Libre sensor this morning and activated it with the reader. After the startup hour the first reading was telling me I was hypo (2.5mmol) however when I read the sensor with my phone I wasnt hypo (4.6mmol). I checked with a blood test which said 8.6mmol and obviously didnt help.
    The Freestyle Libre reader has maintained a reading 2mmol below the phone app. This means I am registering as low all the time.
    Anyone got any ideas?

    I always wait 24 preferably 48 hourrs before activating my sensor. Abbots recommend 8 hours. Check tomorrow to see if it improves.

    FS is notoriously inaccurate under 4 and you need to follow up with a finger prick if it is telling you you're hypo.

    That's weird. I've never known the reader and app to show any difference. The sensor has s number, the scan is a digital exchange. The algorithms are, should be the same.

    Did you update the reader software a couple of months back?

    Hi , thanks for the reply. Yes, my app is up to date. I don't think I can update the reader's software. I have attached two images: one is a screen shot of the app and the other is a photo of the reader. You can see theb graphs are offset.

    The reader IS updateable. I can't remember the link, but it is very straight forward. A search of the Libre website should find it.

    My results with the Libre have been less than stellar, too. It's been reading in the 3's all day but when I test this evening it's 5.3. For the first day, this sensor tracked quite well.
    Sorry, can't help with the Mac.
