Glimp

You can use it instead of the libre app. But you will need the libre app or reader to initially activate the sensor. Also if your DSN needs to see the data they may want it on libreview. Once its activated you open the app and simply scan as normal. It will then show you the graph. You can visit their website for the guide, but its easier to just have a play around with it.

Or just ask away as I use it and I'll help as much as I can.

My aim is to calibrate the sensor with finger pricks because my readings are alwaus out

Can anyone tell me how to do this??

Open the app, hit the + button at the top right. Enter the glucose measured by the meter in the Glucose box, then hit the save icon at the top right. If done right, it will show a dot on the graph of the value you entered. If its too far out after a few entires it will automatically calibrate the readings.

What do you mean by then your levels are stable?? Sideways arrow??

Generally don't do it after eating or after insulin s it will fluctuate. Leave it a few hours. If it changes too much anyway I think Glimp accounts for this and ignores it.

Here's how I think about calibration.

When I wake up there's a fair chance bg and ifg will be about the same and stable, because I've been resting and had no insulin or food for a while.

If I test bg at 4.7 but libre scans at 3.6 I know that there's a fair chance the sensor is misinterpreting the ifg as 3.6 because ifg and bg are likely to be the same on waking and the bg is telling me it's 4.7, so the ifg is likely to also be 4.7 because I'm stable.

So that's a good time to input the 4.7 into glimp to tell it, see that stuff you're getting from the sensor which says 3.6, it's not 3.6, it's actually 4.7.

It means glimp can make a lot more sense of info it gets from the sensor in later scans.

But doing this as calibration only works when you're stable, i.e. bg has been running relatively flattish for an hour so.

If bg is flying up or down sharply there will be big differences just cos of biology between bg and ifg. So there's no point in calibrating when you've just dropped from 9 to 5 in the space of twenty minutes. If you typed 5 into glimp in that situation it is telling glimp ifg is 5 but it could be anything, 6, 7, 8 or whatever, but not 5, so that calibration would just make it worse.

I made the mistake in my early days of recalibrating too often to try to chase moving bg, but that just makes it worse - be patient, defer a calibration till stable, and only calibrate once or twice a day.

I use a different rig, libre, miaomiao and xdrip+ - get the calibration right and it can be astonishingly close, my current one is literally only about 0.2 out over the last few days.

Good luck
