Do these patients keep a log? No. Will they keep a log if this is done with a device? Maybe. Will they do it if they are rewarded with a good analysis? Maybe.
It all depends on their will to do that for 24/7. With my free project Glucosurfer.org the data can be managed in full anonymity. I try to motivate people to log their numbers and to use social platforms like TuDiabetes to discuss their glucose control in times of crisis. You can take a look at my diary with the following link. There you can use the mouse to drag from one day to the other. Furthermore there are several diagrams to visualize my glucose control. Some of these diagrams are unique and you will need some time to read them correctly:

Our project is not an application but an online service. If you want to have an impression how this will look like on the iPhone you can open the following link with your iPod Touch. Please rotate your iPod to landscape view (90° rotation) for the analysis part. On this example page you can enter some values to get an impression. The example is for a patient on MDI with NovoRapid and Lantus. The carb factors are coming from the settings of the user tudiabetes:

If this is a valuable tool for kids & teens really depends on their mindset towards D. In my opinion it is a great offer and it has really helped me to log my numbers carefully. When ever I see a negative trend in the diagram proportional trend I try to find the problem. This helps me to stay proactive and to catch a negative trend before it will be visible in my A1c.
