Discovering the target audience

The primary reason startups fail is that they do not meet market needs. According to an article published by Forbes, fitness apps manage to retain only 15% of users in the first thirty days. It is why discovering the right audience for the app is crucial.

Defining your target audience before building an on-demand diet app is critical. Are they diabetic people? Or working professionals? Under what age group do they fall? Answering all such questions creates a clear image of the target audience. Targeting certified nutritionists, trainers, and fitness coaches can be a good idea as they can answer all health and diet-related questions of your app users.

Now that you have the right target audience for the app, you have to pick the features for it.

Key features to keep the users engaged

What makes one app stand out from the rest? The types of features and the usability of each element engage the users. Before you plan an app, it is vital to understand the must-have features that would make it worthwhile. Every feature that goes on in the app should provide significant value to the users. 

For any app to be a user-engaging app, its UI/UX design should be engaging and easy to work with. Hence, you must ensure that the login is brief for the users. Often it should require a few details like name, mobile number, location, etc., to register the users quickly. Other features include:

Diet chart/plan 

When users log in to the app would want to get personalized help regarding what they should consume on a daily basis. A diet plan feature will help them connect with expert dietitians who will make personal diet charts.

Therefore, your app should connect with certified and professional dietitians who can then communicate with the users through the app. It is the diet plan that will bring the users into healthy eating habits, and that would be accessed the most by them.

Healthy diet recommendations

Healthy food recommendations are a top feature of building an excellent dietitian app. Any user that comes to the app would want smart suggestions every day as they don’t want to invest time in researching.

These suggestions could be in the form of a live consultation, blogs, or a fact shared by professional nutritionists. The feature will keep the users engaged, and they will look up more such information.

Water consumption feature

Water consumption feature has become a popular feature. Proper water consumption plays a significant function in weight loss– one of the top reasons people register on diet apps.

Once the user puts in all the details regarding weight, height, body mass, etc., your app can suggest the right amount of water consumption. With this feature, you can send reminders to consume sufficient amounts of water regularly.

Shopping assistance

Often diet conscious people try to make themselves. Firstly, you could provide recipe books and guides that cover meals with proper nutrition. 

Secondly, the shopping assistance feature will help them identify the perfect ingredients that they would need to make the dish. This add-on feature will ensure they are on the right track and build better trust in the application.


Feedback features also hold a valuable place in the diet app. Let your users provide their ratings and reviews for the app freely.

It will help the new users discover why they should use this particular app and how each feature will help them personally.

Barcode or QR scanner to identify calories

People are getting calorie conscious. They want to count their calorie intake before they even take a bite.

Adding this feature to the diet app will give another reason for your target audience to use the app. Let them scan the calories, record them on the app itself, and ensure they consume just the right amount.

Push notifications for delivering messages

Notifications are the most crucial part of any app’s growth, as everyone checks their phone when a notification pops up. You, of course, don’t want your users to miss out on anything latest and essential.

So be it the latest offer, any promo code, a special discount, or a personal reminder to the user, every message can be delivered beautifully through push notifications.

Third-party integration

The app must allow for third-party integration. It will be helpful when the user wants to make a payment for any purchase, subscription, or consultation with a nutritionist.

Also, integration with apps like MyFitnessPal and BigOven will give them top nutrition feeds. Such information will help them stay updated with the latest health trends and tips.

Google Fit and Apple HealthKit integration

Apple HealthKit and Google Fit monitor and store a user’s fitness details like weight, height, step count, etc. It helps the user keep track of their physical activities every day.

Integrating these apps with yours will prove to be very beneficial as with these insights, you would be able to provide better suggestions for their diet and physical activity. 

5 ways to make money through a diet app

There are five revenue models for a diet app. You can choose the model that fits your business demands and later integrate other revenue models into the app. If you start with a freemium model, you could also add the subscription model in the future. The subscription could be to the article, guides, etc.

Likewise, you could practice this exercise with other revenue models and discover what works best for your brand.

Freemium model

Who doesn’t like free services? Freemium is an excellent way to pull in more customers. You could start by providing basic services of the app free of cost. Once the users are satisfied with the services, they are most likely to purchase a plan in order to access premium services. 

Paid apps model

This model works by paying only once for using the application. It is always better to provide a free trial to the users so that they know that the app is exactly what they need. The trial period could range from a few days to weeks or even months. 

Subscription model

One of the most practical methods to make money off a diet and nutrition application is through a subscription or membership business model. Users will be encouraged to extend subscription validity and select more expensive membership packs if they have the option to customize their membership packs and receive regular discounts. To gain their trust and lower the rate of app usage termination, give customers the choice of a range of subscription lengths, such as weekly, monthly, or yearly.

In-app advertising model

Smart advertising through the app is a good way to generate revenue. For instance, you could run ads promoting fitness events, food supplements, sportswear, and more. For every ad you run, you can charge a fixed amount of money from the clients but ensure that the ads are relevant for your users.

Sponsorship model

You can promote other businesses that are not your company competitors by adding only the logos of various brands to your app. Exercise facilities, sportswear manufacturers, food producers, supplement manufacturers, and other businesses are ideal for emphasizing nutrition-related applications. Under mutually beneficial terms, you can market yourself and receive advertising.
