I was just diagnosed with Type II a few weeks ago, & I knew the best way to track my sugars (the way I would consistently do it, anyway) was with my iPhone. I tried several free apps & overall have been happiest with this one. I especially like the Google Health interface. My only request would be an option to manually input readings via some keypad/scroll wheel method like the other apps (perhaps this could be a user enables option?). I sometimes have trouble getting the slider exactly where I want it, & I just think a more straightforward input method might be convenient for some people. I had no problems setting up custom labels for all the different times of the day I check my levels. The Twitter feed is a nice addition to read what others are doing. Thank you to the developers for creating this free useful app.
