So... Here I am being told that I'm possibly type II, needing to monitor my levels for a while. Being the inherently lazy person that I am, I opted for finding an app instead of using pen and paper. The higher rated apps all had adds... F#&K ads. They were in the way of everything! My laziness will not tolerate extra clicks to get to my goal of minimum effort. That's when I found this great app. NO ADS! Simple GUI. 10/10 would recommend to a friend (but hope they wouldn't ever need it...)

this app is simple, straightforward and easy to use. my only complaint is that there is no option for testing sugar right after waking up. I currently fast most of the day and eat a meal replacement later in the day. I am prediabetic and trying to lose weight but the only options that help the algorithm determine whether or not the reading is in the right range for your circumstances and time of day. I'd really like to see a few more options and settings that improve the algorithm.

UPDATE: I just had a new issue and support is still the best. Every question I had were answered within minutes, honestly minutes, by a tech named Timur. He even followed up to be sure I was ok. There is nothing better than a great app with fantastic support and this has both! You can't go wrong. My only issue is that I need an app that will calculate my A1C from blood sugar readings and this app doesn't do that. I wish it did because the support is exceptional!
