I tried this app awhile ago and found it annoying. I thought it just map results like the freestyle libre 2 did but it keeped bothering me about checking with some person my results. I don't want advice just chart i can print out for dr. Stop with the ads already, annoying. Update: the app has gone through changes and has become more user friendly. I'm using it to track my accu-check guide and print reports for my Dr. Now will not print report unless i scribe other words pay.
