Here are a few examples of the questions.

At the bottom of this page is a toggle button that allows to decide whether or not to customize the recommendations they will receive from the application, in regards to managing their diabetic condition, to be more specific to themselves.

The Glycemic tracking page shows the user their average blood sugar values, average carbs, insulin, percent range that you are within your threshold, number of measurements, and ratio of times that you were either above or below the threshold that the user sets. This is done for six time frames, current day, past 7 days, past 14 days, and the past 1, 2, and 3 months. To see these time frames, swipe left or right on the glycemic tracking page. This page also holds a graphical representation of the user’s glucose numbers for the corresponding time frame. At the bottom of the page are 3 buttons that allow you to add a new log entry or look at his/her log entries for the past week.
3.3 Nutrition and Exercise Tracking
The nutrition and exercise section allows you to see a list of all foods that you have eaten for the past week based on the meal that you entered them in for and in reverse chronological order. At this page you can also delete a food from the database. Be warned however, deleting a food from this page will not affect the log entry that the food was added in for and thus, the amount of carbs that are counted for the deleted food will not be subtracted from the log entry. This causes the number of carbs that are reported by the glycemic tracking page will not match up with what is in the database. In the end the user might be reporting more carbs than he/she has actually eaten.
