Combined, the Apple App Store and Google Play Store offer over 8 million apps, and 3% of them are connected to health and fitness. Half of all nutrition applications (Product ScannerCalories in foodSimple Macro, etc.) have only one function, while the best diet and nutrition apps (MyFitnessPalMyNetDiaryFatSecret) offer a set of functionality: calorie counters, food diaries, recipes for healthy food, barcode scanners, daily meal plans, and shopping lists.

But are multi-featured nutrition tracker apps profitable? In 2018, MyFitnessPal was the top fitness and nutrition app, with $62 million in revenue. Lose It! was the second highest-grossing diet and calorie tracker app, with nearly $12 million in gross revenue. These apps are free to download and make money through in-app purchases.

In this article, we’ll talk about the best diet and nutrition applications on the market, giving you thorough information on how to create a diet app and what functionality to add. Below, we are also explaining why food diary apps have become popular among users from different countries with diverse eating habits. This information will help you decide on the type of application you want to build and features for your own app for diet.

Types of diet and nutrition apps

Vegan and vegetarian nutrition apps

Vegans and vegetarians should always monitor calcium, magnesium, Vitamin D12, Vitamin D, Vitamin B6, and iron intake. A vegan nutrition tracker app can track nutrients based either on a user’s custom goals or recommendations from the US Department of Agriculture (USDA). Nutrition trackers can warn when users consume too much fat, sugar, or sodium, and can provide plant-based recipes. Vegans, vegetarians, and people who would simply like to eat more plant-based food choose the following food and nutrition apps:


HappyCow simplifies the search for vegan and vegetarian restaurants. According to its motto, the app “makes cows happy because a user avoids eating meat when dining out.” With HappyCow, users can:

  • search for vegan or vegetarian restaurants in a certain area
  • filter restaurants depending on the type of diet
  • save favorite locations

HappyCow is one of the best diet apps, as searching is fast and convenient, features aren’t complicated, and there are plenty of restaurants to choose from.

When users pick this application for their mobile diet planning, they can:

  • look through recipes
  • enjoy simple preparation thanks to step-by-step photos
  • receive daily inspirational messages

Diabetes nutrition apps

According to the American Diabetes Association, nutrition what people eat affects their blood sugar levels. While doctors help to personalize nutrition therapy, best nutrition calculator apps help patients track their health 24/7 so they can share thorough reports with their doctors. Such apps are new, yet the idea is profitable.


mySugr, founded in 2012, presents itself as an app for “all-around care for people with diabetes – made by people with diabetes.” The application is loved for its deep understanding of this health issue, advice and information from certified diabetes educators who have been dealing with this disease for years, and exclusive features such as:

How to monetize an app

As we wrote earlier, in 2018, the best food nutrition apps and major market players like MyFitnessPal and LoseIt! raised revenue of $62 and $12 million respectively. How exactly did they manage to succeed financially after being launched? There are four strategies to monetize your diet and nutrition app.

In-app ads. There’s a clear reason why advertisers are now strongly attracted to the mobile app market. Around 20% of all smartphone users check out websites, while 80% prefer browsing applications. 

As you invest in diet plan app development, you can benefit from placing ads. For that, you need to decide on:

  • mobile ad network (a broker between the app and advertisers)
  • format of your in-app ads (banners, interstitial ads, native ads, video ads)
  • pricing model (cost per action or click)

Paid mobile applications. By deciding to launch paid mobile apps, you ensure that all app downloads are paid off. What’s the benefit for users? With a single download payment, users no longer need to pay monthly subscriptions to access extra features.

Advice from Steelkiwi: Offering a paid nutrition calculator app is more challenging than attracting users by offering a free app. Still, this monetization strategy ensures there’s revenue from each customer.

Freemium. This monetization strategy is the most popular among top nutrition apps. It implies charging application users for advanced features only. You can integrate freemium monetization in one of three ways:

  • by setting up your own virtual currency: as users buy the currency, they can enter advanced features
  • by offering application users to subscribe to enter extra features 
  • by allowing subscribers to pay for each advanced feature unlocked

Sponsorship. You can find a brand or business that is willing to sponsor your diet planner app development and its further maintenance. Actually, there are many companies eager to support nutrition app development. Below, there are four main reasons why:

  • to strengthen their brand image
  • to access new audience and future-to-be customers
  • to stand out from their closest competitors
  • to increase the level of brand involvement in the nutrition and diet community

Advice from Steelkiwi: The sponsorship monetization strategy is effective since it allows startups with an idea to become financially supported without compromising user experience. 

Nutrition app development cost

The price-related question is a tricky thing. Even for an experienced team, it might be hard to say about the exact cost to develop a diet and nutrition app. Nevertheless, based on the feature-set, the number of platforms, and applied technologies, you can come to the estimated cost.

To start with, you need to decide whether to outsource the development or hire local food app developers. Some businesses find the physical proximity to local teams as their most meaningful argument. But it’s the only argument since remote teams also meet organizational requirements, have a high level of expertise and are deeply involved.

But the same or even better quality of a final product is not the only benefit of working with outsourcing companies. It’s no secret that the average cost of app development depends on the geographic location of the team you plan to hire.
