User Persona


My Diabetes Meals (by: Doug Warren)

I have identified the following possible user personas to represent different types of users for my app.

  1. Doug: iOS developer with Type 2 diabetes using One Drop and Diabetes Meal Plans
  2. One Drop Mobile users
  3. Diabetes Meal Plans users
  4. All persons with diabetes
  5. Any healthy cooking enthusiast

Initially I will just work on the user persona for Doug, and expand to additional personas for various market segments as design and development proceeds.

He has had Type 2 diabetes fo 12 years and takes Metformin (1000 mg) at breakfast and dinner, as well as insulin at bedtime and before meals as needed. He has an Apple iPhone, One Drop Premium subscription, and Diabetes Meal Plans VIP membership. He wants to get an Apple Watch soon to help further with his health.
