Why we create this app

Unique problems that only women have

FeminaFast focus on the problem women have due to their special needs. Women's hormone cycle affects their metabolism, mood swing, and their well being. Going through the journey of making this app as best as possible, we learn a lot of nutrition, hormone, psychology, etc. It makes us feel different because as men, we also could take part in the journey of empowering women. We develop this app with our mother, sister, girlfriend, and wife in mind. We hope it will help them in their lifetime. Below we will show you how we found this app.

Project Background

Empower women's health in their 30s

Your thirties mark a transformative decade, bringing both personal and professional growth. While this stage is filled with exciting opportunities, it also presents unique health challenges. Understanding these challenges and embracing a holistic approach to well-being is crucial for women in their thirties.

Essential Question: How can women effectively improve their health and well-being during their 30s?Challenge: Addressing the unique health challenges faced by women in their 30s, including:

  • Declining metabolism and muscle mass: As women enter their 30s, their metabolism starts to slow down, leading to a gradual decrease in muscle mass if not addressed appropriately.
  • Increased risk of chronic diseases: The risk of developing chronic diseases like high blood pressure, heart disease, and diabetes increases with age.
  • Hormonal changes: Fluctuations in estrogen and progesterone levels can affect women's energy levels, mood, and sleep patterns.

Guiding Question: What constitutes a healthy lifestyle for women in their 30s?

  • Physical well-being: Maintaining a healthy weight, engaging in regular physical activity, and prioritizing adequate sleep are crucial for overall health.
  • Nutritional balance: Consuming a balanced diet rich in fruits, vegetables, whole grains, and lean proteins ensures the body receives essential nutrients.
  • Mental and emotional well-being: Managing stress, fostering healthy relationships, and engaging in activities that promote relaxation and enjoyment contribute to mental and emotional well-being.
Why are we focusing specifically on people in their 30s? To put it simply, we found that most people tend to focus on their health more in their 30s due to the potential health issues associated with aging.
User Interviews

Knowing users needs through user interviews

I interviewed three women in their 30s who had tried different diet methods to improve their health. Here are the shorter version of the user interviews:

User Interview 1

Glenda is in her 30s and has tried calorie counting, which was effective. However, she only does it during the dieting phase because it is a bit of a hassle. She has gotten used to counting calories over time, so she now does it automatically. She finds calorie counting to be a relatively effective method. She has never tried the keto diet or intermittent fasting, but she has researched them. She has not yet tried any other methods, so she relies on herself to determine her daily energy needs.

User Interview 2

Stephanie is in her 30s and wants to diet because she is tired of buying new clothes and replacing her wardrobe. Her BMI is also overweight. She tried ketosis, which was effective in helping her lose weight, but she developed headaches after a week. This interfered with her work productivity. Her diet consultant then recommended intermittent fasting, which was effective for her.

She now does intermittent fasting on a daily basis without feeling burdened. Her weight is now stable because she is used to skipping breakfast and not eating outside of her fasting window.

User Interview 3

Danielle is a factory worker who started dieting because she developed health problems in her 30s, such as high cholesterol and high blood pressure. She tried calorie counting, but she found it too inconvenient. She has time to exercise, luckily, because she has a gym at home. She then tried the keto diet and intermittent fasting because her friends had success with them. When she wanted to lose weight quickly, she did both methods at the same time. She initially experienced headaches and fatigue, but all of the symptoms went away once she entered ketosis. When her weight stabilized, she stopped dieting and will start again later.


However, so far, she has not experienced any yo-yo effect and her weight has remained relatively stable. Also, because she has been doing intermittent fasting, she has already formed the habit.

User Interviews Summary

Based on our interviews, I found that the following are important considerations for women in their 30s who are looking to improve their health:

  • Consider your individual needs and preferences. What is important to you? Do you want to lose weight quickly or gradually? Are you willing to make major changes to your lifestyle?
  • Be realistic about your expectations. It takes time and effort to make lasting changes to your health. Don't expect to see results overnight.
  • Find a method that works for you. There are many different diet methods available. Experiment until you find one that you can stick with.


I also found that the following methods were effective for the women I interviewed:

  • Intermittent fasting can be an effective way to lose weight and improve your health. It is relatively easy to follow and can be done anywhere.
  • Calorie counting can be an effective way to lose weight if you are willing to put in the effort. It is important to be accurate when counting calories and to be prepared to make changes to your diet.
After all of these researchs, we decided to focus on physical well-being especially weight loss
User Persona

Defining our target audience needs

Based on our researchs above, we make user persona to better understand our user. Here’s our user persona:

Vina, a 30-year-old sales manager, seeks weight loss solutions that are time-efficient and minimize side effects. She also experiences hormonal fluctuations that impact her daily emotions.


Needs and Goals:

  • Vina desires to lose weight without sacrificing her quality of work or family life.
  • She seeks a weight loss approach that is low-stress and easy to incorporate into her busy schedule.
  • Vina aims to improve her overall health and well-being to enhance her quality of life.
Customer Journey Map

Delve deeper into users behaviour and identify opportunities

Creating a customer journey map provides several benefits for understanding and improving the customer experience. It can also help identify opportunities where it can be developed as app main feature.

Expert Interview

Insights about health & weight loss in general

We also did an interview to someone who is an expert about health, & lifestyle here’s the summary:

Kamya, a personal trainer with over 10 years of experience, believes that protein is the most important nutrient for the human body. Carbohydrates are not as important unless you are doing something that requires short-term, intense concentration or heavy work.

Kamya also believes that many people are mistaken about losing weight. Losing fat is more important than losing weight. Many diets will cause people to lose muscle as well, which is not ideal.

In the end, all diets will cause people to lose muscle. However, if protein consumption is sufficient during the diet, drinking enough water, and exercising regularly, the effect of losing muscle can be reduced.

Kamya believes that diet is not healthy to do in a prolonged period. However, the effects of diet are less than the effects of being overweight.
