Just felt compelled to share... Been using the Freestyle libre now for about 3 months and find it a great piece of kit especially been able to scan the sensor to see trends and impending Hypos etc. My only issue is that the readings can differ from the actual BS readings between .5 and 2 mmols and the information from the reader is restricted to show data on the graph in 2 hr intervals. By chance I discovered an app called Glimp which can be used either instead of or along side the Libre reader. The difference I have found, however, are unbelievable!!. Firstly, I have read that the app can still obtain data from the sensor for a number of weeks after the 14 day limit! The app also seems to be more in line with actual BS readings examples are as follows
BS reading........ Libre Reader........ Glimp app
7.5....................... 8.7 ....................... 7.4
7.5....................... 8.5........................ 7.8
7.4 ...................... 9.1........................ 8.2
7.6 ...................... 9.3........................ 8.3
7.5....................... 8.6........................ 7.4
4.5....................... 4.9........................ 4.4
8.6 ...................... 9.7........................ 7.9
Secondly. As I am going to officially be pumping on the 28th of this month I was planning to use the info from the libre reader to help me with a starting point for insulin adjustments however as the info on the reader shows the graph plotted over 2 hour periods I would need to estimate an approximate time my blood sugars changed... however, with the glimp app you can scroll along the graph line which shows the exact time of changes which for me will be much better for example last night my readings were stable until 12:07 then dropped until 01:52 dropping by 1.8 mmol then remained stable until 03:39 then began to raise! Another great feature is that there is also a CGM function which will set of an alarm if you go outside your pre set range (which I am eager to try out) only thing with this is that you need to ensure your phone is attached to the sensor. And finally what I am impressed with is that you can also input your actual BS readings and the app will calibrate the data. Overall I am really impressed as not only will I save money but also get more accurate readings!!
Have only been using the app for 1 day along side the Libre reader but so far ... wow!!!... Has anyone else used this app? if so would be interested how you have found it and if the CGM function works as well as hoped
