  • It’s difficult to deny that a healthy lifestyle and nutrition are global trends now. Moreover, it doesn’t seem like a short-term craze, since every year the popularity of nutrition applications, diet plans, healthy food recipes is only growing.

    About 97% of Americans say that healthy eating is very (72%) or somewhat (25%) important”. - Pew Research Center

    Many Startups try to catch this wave and find their niche on this growing market. I bet my avocado toast that you are one of them, too! If yes, keep on reading since we’re going to share thrilling insights on how to create a diet app MVP for your Startup!



    📱 Key Nutrition App Features: Make a Backbone of Your MVP

    One of the most challenging parts in developing a diet app is choosing the right scope of features for your application:

    • On the one hand, if you omit some essential features and your mobile Product will lack some functionality, it probably won’t meet users’ expectations and won’t solve their problem. Therefore, forget about Product-Market Fit and any possible success.
    • On the other hand, if you make your app too complicated and spend a lot of resources and time on development, it may not work out well since you should better get a PoC and secure funding prior to adding some advanced functionality.

    Сonsidering all of the above, we decided to split the features for nutrition app development into 2 categories: the ones that fit the MVP-Scope and the ones that can be implemented after you pitch your Project to investors and get resources for further scaling.

    However, we understand that you have your own idea. Therefore, we reviewed the development process of some generic diet app so you can have an idea of how the whole process goes and looks like.

    At first, let’s take a closer look at must-have features you need to build a nutrition app.



    🥇 Top 4 Nutrition App Features that Form a Core of Your App

    The list of features below is quite basic for all diet applications. However, you may also add some features that make up your USP or needed to take a specific niche on the market (we’ll review them a bit later).



    # 1: Registration 📝

    Personalization usually means a lot for users of health applications. To provide the most value, such apps should take into account age, sex, different health indicators like weight, height and so on.

    Therefore, the registration process allows linking your application to each specific users and provide him with personalized content. It also ensures that their data won’t be lost if, for example, they change their devices or re-install your application for a reason.

    However, you should be super-attentive when working with and storing any personal data. The GDPR and other regulations in this field are rather strict, so we’d recommend you to store as little personal data as possible so you don’t have any problems with breaches and hackers.

    We’d also recommend you to implement a Social Login feature as you create a diet app. It allows going through a usual sign up process when users are required to enter their name, surname, date of birth, email etc. Instead, this info is taken from a user’s social network profile (usually it’s Facebook or Twitter) which facilitates and speeds up the whole process.



    # 2-3: Food Logging & Dashboard 📊

    This is another essential feature for any diet application. Actually, it works like Wikipedia or a food “dictionary” which stores the information on how many calories there are in each meal/product. So when users enter the type and amount of food, the application shows an average number of calories that a user has likely consumed.

    However, it would be nonsense if you had to enter this information manually. Luckily, there are many different APIs that let you easily build a nutrition app and integrate already existing databases. By the way, we’ve listed some of them closer to the end of the article.

    Don’t forget that people use diet applications not just to check the number of calories in their food, but also (and mostly) to track their nutrition habits.

    This means you should also create a Dashboard Screen as you make own nutrition application. It will allow users to check a daily/weekly calorie intake and plan their further meals based on this info.

    Since it’s going to be one of the most used screens in your app, pay special attention to the minimalistic design and appealing UI.



    # 4: Hydration 💧

    If it meets the scope of your Project, we’d also recommend you to add a Hydration Screen during the nutrition app development. Appropriate water consumption also means a lot to people who care about their healthy eating habits.

    water-intake

    The screen itself looks similar to the Dashboard Screen. Taking into consideration a user’s parameters (height and weight), the app calculates the optimal water intake and visualizes it. The way you do it is only limited by your imagination. For example, it may be the corresponding number of cups or just one big drop that is gradually filling up as the user enters new water intakes.


    So the features above make up the backbone of your diet app. It means that you should definitely include them in the scope of nutrition app development.

    However, we’ve also listed some features that can help you define your USP or may be added later when you scale your product. Let’s take a look!



    🔝 8 Extra Features For Your Nutrition Application

    # 1: Diet Plans 🗂

    Many users expect your application to be a healthy eating helper rather than just a calorie calculator. Therefore, it may be a great advantage from their perspective if you offer them a more personalized experience (if they need to lose weight or to build muscle mass). Again, the way you do it depends only on you.

    For example, you may use some automatic algorithms that will take users’ body parameters and offer a more or less universal solution. Or maybe you have enough resources and experts to provide customers with private consultations, which can also be your USP.

    No matter what approach you’ll choose, the Diet Plans Screen will look quite the same: a user’s current plan, needed daily/weekly calories intake (you can update the Dashboard Screen with this info, too) and some general recommendations.



    # 2: Barcode Scanner 📸

    This is a nice and seamless alternative to the manual food login. Your customers will get a few advantages at once if you create a diet app with this feature:

    1. When possible, users will be able just to scan a barcode which will significantly improve the overall UX.
    2. They will also get more accurate data on the number of calories since it won’t be just some average estimate (such information will be provided by a producer).



    # 3: Shopping List 📄

    Want to encourage users to open your application even more frequently? A Shopping List Feature is something that can help you with this as you make own nutrition application.

    The simplest option is to provide users with a possibility to manually enter the needed goods. Yet. the UX can be greatly improved if you allow selecting products right from your food database.

    Also, if you implement the Diet Plans Feature, you can allow users automatically import some of the recommended products that match their meal plan to the Shopping List.



    # 4: Integration with Wearable Devices ⌚️

    Many people want to know not only how many calories they eat but also burn during a day. That’s when you may remember about wearables while developing a diet app. Fitbit, Jawbone, Apple Watch or Android Wear are the main ones, however, we’d recommend covering as many options as possible to satisfy users with less popular devices, too.

    Despite this feature doesn’t directly relate to nutrition, it can be rather useful to your audience. People who track their weight are usually doing some sports (or at least jogging or cycling). Seeing the difference between burnt and eaten calories during a day will help them to figure out whether they’re having positive dynamics or should change something about their eating/sports habits.



    # 5: Recipe Book 📚

    For many people, the worst part of healthy eating is that they have to cook on their own because ready-to-cook meals are usually not healthy at all.

    recipe

    A book of pre-made healthy recipes is something that can help your audience, save them a lot of time and give even more reasons to use your app more frequently. It will be even more convenient if users are able to add the recipe ingredients right to their in-app shopping list.

    It’s possible to go as far as you want with this: just limit yourself to written recipes with photos or implement step-by-step voice instructions like in the Sidechef app.



    # 6: Live Experts 👩‍🍳

    You can also build a nutrition app with a Live Experts Feature for those, who are seeking professional help and want to personalize interaction with your app as much as possible.

    Your dietitians can provide consultations either through an in-app chat or via video calls, which will bring the UX to the new level.

    Moreover, this feature can be used as an additional monetization solution. It will cover the needs of the ready-to-pay audience that looks for professional guidance from your experts.



    # 7: Blog | Dietary Tips 📖

    Another extra feature that you can implement when developing a diet app is a Blog:

    • For newcomers, it will be a great source of information about healthy eating habits - what to eat, how often, at what time and so on.
    • The experienced audience may use it to read the news and actual researches on this topic.

    Blog articles can also have a great marketing effect - if people enjoy the content you give them, they’re likely to share it on social networks and become promoters of your brand among their family and friends.



    # 8: Gamification 🎮

    When it comes to mobile apps, people like challenges more than anything. Gamification elements give your customers a sense of competition and encourage them to be active users and to obtain new achievements.

    Badges, points, tiers, ranks, titles - it all works well if you want to keep your retention rate high.

    To achieve even better results, you should make own nutrition application in which gamification elements are connected with some real benefits. Users will be more motivated to collect points if they can exchange them for a personal diet plan, limited access to paid features or a consultation with your nutritionist.



    ⚙️ Tech Stack

    We at Stomotion can recommend using the following tech tools to build a nutrition app:

    • You will definitely need to integrate some Food Products & Ingredients Database. For example, it may be INRFood, USDA Food Composition Databases, MyNetDiary, CalorieKing or any other you’d like. If you aren’t sure which one fits your Product best, get in touch and we’ll help you to make the right choice.
    • Pay a special attention to the Edamam Dev Platform. It provides a bunch of APIs for different cases, including food database, recipe search, meal recommendation engine and a few others.
    • Calorie Mama API enables instant food recognition via device’s camera.
    • In case you’re thinking about integration with wearable devices, Fitbit, Jawbone Up, Garmin, Nike+, Misfit SDKs and APIs are necessary to you (depending on what manufacturer you choose).
    • If you don’t plan to integrate wearables, you can still get info about users’ daily activity (including walked distance and burned calories) using Google Fit’s (for Android) and Apple HealthKit’s (for iOS) tools.



    💰 Cost to Build a Diet App

    Here are our estimate of costs to create a diet app. Check it out:

    So the diet app development costs are between $14-18,000 without the extra features like blog and between $18-23,000 including them. We calculated the costs to create a diet app using the $40/hour rate that is standard for Eastern Europe. However, this is an approximate estimate so if you want to get an accurate numbers for your project, drop us a line!



    💡 Conclusion
