How to Build a Diet and Nutrition App

Over the past few years, health-conscious eating has been trending. More and more people are trying to develop a healthy diet and track their progress using nutrition apps. Due to the high demand, businesses want to break into the mHealth market by developing a diet app.

If you’re planning to build a diet or nutrition app, you’ve come to the right place. In this article, we’ll provide fresh insights into diet apps: what they are, who their target audience is, stages of development, must-have and nice-to-have features, and revenue models.

What are diet and nutrition applications?

Diet and nutrition apps help users maintain a healthy diet. Take Lifesum as an example. It’s a nutrition app that helps users lose weight, be healthy, and get stronger. ShopWell is a nutrition facts app that finds foods that meet users’ needs, goals, and lifestyles. Another great example is MyFitnessPal, the leading health and fitness app in March 2019 according to Statista. MyFitnessPal allows users to determine the calorie content of food and adjust their eating habits to lose weight.

There are different types of nutrition apps, including calorie counters, diet trackers, meal planners, and marketplace platforms that connect users and nutrition coaches. There are also apps designed for niches: pregnancy nutrition apps, bodybuilding nutrition apps, vegan nutrition apps, and diabetes trackers, for example.

Who uses diet and nutrition apps?

Top app ideas are worthless if your app doesn’t create real value for its users. CB Insights states that the biggest reason why startups fail is not meeting a market need. Learn your target audience inside and out before you develop a food nutrition app. Know their demographics and the problems they cope with to offer a one-of-a-kind solution. Below, we give you statistics on who uses nutrition apps. Yet this is just an overall picture. Make sure you know who you’re going to target with your particular diet and nutrition application.

  • The typical user of a diet application is young. According to a Statista survey in 2017, 26% of 18- to 29-year-olds and 17% of 30- to 45-year-olds use a nutrition tracker app regularly.
  • Users download mobile healthcare apps to track exercise, monitor nutrition, reduce weight, and learn to work out, according to research published in Translational Behavioral Medicine.
  • Losing weight and keeping it off was a New Year’s resolution for 45% of Americans in 2018, according to Statista. A 2019 Statista study shows that over half of Amercians would like to get more exercise and eat healthier.

How to create a diet and nutrition app: Stages of mobile app development at SteelKiwi

Regardless of the platform you choose ― iOS or Android — your app will go through the following stages of development: discovery, requirements and prototyping, design and coding, and testing and deployment.

  1. Discovery and research. At this stage, you introduce your idea to the software development team. At SteelKiwi, we help our clients determine if their app idea is viable by analyzing the market, competitors, and the target audience. Then, we define the key objectives and the core value of the product. After that, we write a product specification document to outline how your application will function.
  2. Prototyping. Once you approve the product specification, our SteelKiwi design team proceeds to wireframing. This saves developers’ time and effort and specifies the app’s structure, features, and navigation.
  3. Code development. This is the longest stage, during which your software development team turns your idea into a product.
  4. Testing and deployment. At this stage, our quality assurance specialist tests the application to make sure there are no bugs. After we verify the app is stable, we publish it to the app store(s).

Features for diet and nutrition apps: Must-haves and nice-to-haves

These are must-have features for any diet and nutrition app:



Registration and personal profiles

Registering is usually the first thing users do in an app. At this stage, users should fill in personal details such as name, age, gender, weight, height, level of physical activity, allergies, and food preferences.

Food logging and dashboard

Users should be able to analyze their eating habits. Therefore, your app should allow them to log food and water intake and visualize their progress on a dashboard. A user’s dashboard can track calories, carbs, protein, and fat.

Push notifications

Push notifications are effective for increasing user retention and engagement. A nutrition journal app should deliver information on progress toward the current goal and motivate users to keep moving toward their goals by reminding them to log what they eat.


App onboarding is important. Make sure tutorials provide clear instructions on how to interact with your app. Apart from onboarding, add a help button in case users have problems.

Nutrition applications can have various purposes, and their features can vary accordingly. Below, we describe features that can be useful for some diet and nutrition apps (or that you may want to include later on).




You can share diet tips, news, and the latest food and nutrition research on your blog. If users find your content relevant, they may share it on social media and thus market your app to their friends and family. Also, you can allow your users to contribute to your blog by sharing their successes and failures in maintaining a healthy diet.

Calorie counter

This feature enables your app to calculate the calories users have eaten and burned based on the data they’ve logged.

Recipe book

You can offer healthy recipes and sort them by keywords, calories, ingredients, and categories. Recipes can include pictures, video, and even voice instructions. You can also allow users to rate recipes.

Shopping list

You can allow users to add groceries to a shopping list manually or import ingredients from a recipe or a diet plan.

Barcode scanner

A built-in barcode scanner helps users to count calories and see accurate nutrition information.

Live experts

You can let users get in touch with diet coaches via your app for expert advice. Additionally, you can make this a paid feature.

Diet plans

A lot of users want a diet and nutrition app to not only count calories but also help them maintain a healthy diet. This is where diet plans come in handy. Usually, a diet plan includes nutritional tips, meal suggestions, recommended total calorie intake (per day or week), and recipes.

Integration with wearables

You can integrate your app with wearables and trackers – Android Wear, Apple Watch, Fitbit, Jawbone, Samsung Gear – to synchronize data on health metrics and physical activity.


To increase user retention and engagement, consider including game elements. You can use points, badges, and ranks to reward users for achievements like completing goals or losing weight. Note: Users are more incentivized to earn points if they can redeem them on limited features or personalized meal plans.
