OnTrack has been extremely easy to setup and use. It can be as simple or as detailed as you desire. You can track statistics from several categories and view them as a graph. On these graphs you can setup your statistical averages so that you can tell when you exceed the norm in the glucose range that you defined. You can also tag each event with notes ie what you did to cause this reading to vary from the norm.
OnTrack also has the ability to track carbs and other personal health stats in much the same way that you track glucose. Helping to keep you on target for diets or other usage.
Of the 4 diabetes management apps I've tried so far, OnTrack is by far the easiest to use and the simplest to see results in an understandable format. Coupled with the ability to quickly export those results to my email, it leads to a very comprehensive way to monitor Glucose, or other vital information.
