Key Tasks: Users should quickly learn how to log food intake, view their BMI, set health goals, and track progress.

Suggestions:

• Use a guided onboarding process to demonstrate the core features (e.g., logging food, setting goals).

• Simplify the interface with clear labels like "Log Meals" or "Calculate BMI."

• Include tooltips or help buttons for less intuitive features.

Key Points: The app should streamline repetitive tasks, such as logging meals or checking daily progress.

Suggestions:

• Implement quick-add options for frequently consumed meals.

• Allow users to scan food barcodes for automatic entry.

• Provide shortcuts, like a single-tap summary of calories remaining for the day.

Key Consideration: The interface should remain intuitive even after a gap in use.

Suggestions:

• Keep the layout consistent and avoid drastic design changes.

• Provide a “Recent Activities” section or a quick reminder tutorial for returning users.

• Use recognizable icons and labels that clearly indicate their functions.

Common Errors: Users might accidentally log incorrect food items, set unrealistic goals, or forget to save entries.

Key Focus: The app should feel encouraging and engaging rather than judgmental.

Suggestions:

• Use motivational visuals (e.g., progress charts, rewards for milestones).

• Personalize the experience by allowing users to set custom goals and preferences.

• Ensure the app is aesthetically pleasing with a clean, modern UI and calming color schemes.

• Provide positive reinforcement messages, such as “Great job staying on track today!”

Conducted user research through interviews and surveys to explore expectations for a calorie-tracking app.

Discovered common pain points such as confusing navigation, lack of personalized recommendations, and difficulty tracking daily progress.

Identified user priorities:

• A simple interface to log food quickly.

• Accurate calorie and nutrient tracking.

• Clear visualization of progress toward weight and fitness goals.

Key feedback example: “I think the profile section should only be at the homepage, no need to add it to the more section page.”

Users need a seamless and intuitive tool to track their calorie intake, manage fitness goals, and monitor progress effectively.

The app must address:

• User accessibility: Simplifying navigation for all user groups, especially beginners.

• Goal clarity: Ensuring users can set and track personalized fitness/diet goals effortlessly.

• Progress motivation: Providing visual cues and motivational elements (e.g., rewards, badges).

Key recommendation: Add a step-by-step video guideline to guide users before starting with CalorieMaster.
