App Evaluation

• Category: Health and Fitness
• Mobile: This app is developed for mobile but can work just as well on a desktop environment, but a mobile version will be easier to track each meal.
• Story: Analyzes users health information to calculate their basal metabolic rate and generate a calorie limited meal plan, geared towards the users fitness goals. The user can track their progress over time.
• Market: Anybody who is health conscious and wants to change their diet strategy, or for people who want inspiration for cooking their own meals.
• Habit: This app can be used often to track all meals, or it can be used mostly as a reference point for framing a generalized meal plan.
• Scope: First we start by generating customized meal plans with recipes, eventually users may be able to upload their own meals. Big potential for creating a large food database, or incorporating lite social media elements.
