Fitness App Development: Featuring our work.

Fitness apps have become increasingly popular, especially with more people focusing on their health and well-being. The COVID-19 pandemic has further accelerated this trend, as people have limited access to gyms and in-person training. As a result, virtual fitness classes have become a go-to option for many. One such example is MyFitnessPal, which has already generated over $1.4 million in 2020 and is on track to become the top-grossing fitness app of all time. With this in mind, it’s no surprise that many people are wondering how to create a successful fitness app.

Wearables can also provide ongoing metrics to adjust workout difficulty levels as fitness improves. This trend is expected to continue in 2024, providing users with a more effective and personalized approach to fitness.

Holistic Fitness

Research shows that there is a strong correlation between physical and mental health. Nearly half of people with poor mental health also have a physical health condition, which can lead to a shorter lifespan. On the other hand, 89% of people report that physical exercise has a positive impact on their mental health. This has led to a growing trend towards treating physical and mental health as a holistic issue. 

Mindful fitness practices like yoga and meditation are becoming increasingly popular, and gyms are offering more holistic health services like mindfulness classes and counseling. Apps like Aura and Happier are also emerging to meet the demand for holistic fitness, offering guided meditations and daily exercises to help people track the connection between their physical and mental health. It is expected that this trend will continue to grow in popularity throughout 2024.

Integrating features related to outdoor activities and routines within fitness app development could cater to the growing interest in exercising in nature.

Ramping up Recovery

In 2024, post-exercise recovery takes center stage with advanced technology such as infra-red saunas and handheld laser devices in gyms. Tech-led recovery options become portable, including affordable massage guns, enabling individuals to prioritize recovery at home. This trend aligns well with the growing interest in virtual workouts and emphasizes the importance of holistic fitness. We might see a parallel development in fitness app features focusing on personalized recovery plans and tools.

Support From a Personal Trainer

Despite virtual and solo fitness trends, personal trainers (PTs) play a crucial role in guiding fitness journeys. Qualified PTs incorporating the latest fitness tech, wearables, VR, and recovery equipment attract modern audiences. To thrive in 2024, PTs should integrate trends like app development, virtual communication, and inclusive, sustainable practices into their services, ensuring a successful year for both trainers and clients. This could involve leveraging fitness app development to enhance communication, tracking, and personalization in virtual training sessions.

Fitness App Development: Fitness App Features

If you have decided to create a fitness app, you may be wondering what features to include in your app. You can brainstorm ideas and consult with fitness app development company to gain a better understanding of what is necessary. Here are some tips to keep in mind during the fitness application development process:

    1. User profile

Fitness and wellness apps need user profiles to personalize the experience. Personal information like age, height, gender, and weight are necessary for accurate tracking. User profiles are also the place to set goals, plan personalized routines, track progress, and earn perks. Customization options are important, such as saving statistics and comparing performance.

   2. Workout planner

A workout planner is a crucial component of any fitness program as it assists people in losing weight and getting into shape. The most popular way to deliver exercises is through video streams, although you may also come across image-based instructions with voice prompts. Since we all have different body types, workouts must be adaptable in terms of difficulty level. Additionally, make sure to include a workout schedule and calendar when designing your own workout planner app.

Here are some suggestions for additional features that would be nice to have in a workout app:

  1. Provide sufficient meta-data for all exercises, such as the required time and equipment.
  2. Make it easy to navigate back and forth within an exercise.
  3. Add a text-to-speech engine that supports multiple languages for voice tips. For instance in our fitness app development we incorporate Google’s text-to-speech API for enhanced user experience.
  4. Include a workout calendar to help users plan their workouts more efficiently.

     3. Notifications

Fitness application development companies are investing a lot of time and money in the notification system to remind users about their workout sessions, offer discounts, and update them on their progress. However, they have to be cautious as push notifications can be a double-edged sword as users may get annoyed and leave the app. 

On the other hand, sending positive messages and motivational quotes is essential in wellness app development. To avoid users turning off notifications, developers need to be creative and allow users to micromanage different types of notifications. Also, quick actions and a log for all notifications in the settings can help users track their progress and achievements at any convenient time.

   4. Integration with Audio Streaming Apps

Working out is a fun activity for many of us but it can be a hassle to switch between workouts and a music player. This is where integrating your training app with popular music streaming services like Apple Music, Spotify, etc. becomes crucial. If you are planning to create a fitness app, here are some tips for adding audio integrations:

  1. Provide users with ready-made playlists and allow them to share their own playlists.
  2. Choose songs with a tempo that matches users’ heart rate or pace.
  3. Highlight tracks that have motivated users to perform at their best.

   5. Meal Plans & Calorie Counting

As a fitness planner app, it is crucial to consider meal planning and calorie counting. The top-rated applications in this category provide detailed information on ingredients and suggest recipes based on the users’ goals, preferences, eating habits, and health conditions. 

To enhance a meal and exercise app, you can add features like barcode scanning to retrieve nutrition data from external sources. You can also dynamically adjust recommended meals based on consumed or spent calories. Additionally, allowing customers to track their water intake is a useful feature.

   6. Educational Content:

It can be tough to maintain our motivation and reach our fitness goals. One solution to this problem is to access educational resources that teach us the basics of diet and exercise. To ensure that your content remains fresh, it is important that you incorporate a CMS (Content Management System) into your fitness and health app development.

Here are a few tips for selecting the most effective educational materials:

  • Tailor the content to your intended audience 
  • Offer bite-sized recommendations in different formats (such as video, audio and blogs)
  • Connect the content directly to the user’s progress in the fitness app 

   7. Live Streaming:

A fitness application should cater to a diverse range of users who prefer to access various information on a single platform. For users who prefer visual information, the app can implement video tutorials that demonstrate specific workouts. Additionally, these videos should be motivating and contain music to encourage users. 

If you plan to create a gym app, it is important to include a class streaming option. Peloton is a perfect model for such an option, and we can learn many ideas from the company. However, what is crucial is that all these features come together seamlessly to create an optimal gym program experience. Therefore, gym workout app development is about finding the right balance of options.

   8. Integration with Other Services and Devices

To obtain an all-encompassing view of user training statistics, we may have to extract information from different tracking sources like Fitbit or Apple Watch. Alternatively, we can integrate with other apps and obtain any data that might be missing.

How to make a Fitness App in 5 Steps

Breaking down the process of custom fitness app into easy 5 steps can make it less intimidating. How can you go from having a fitness app idea to iOS and Android fitness application development?


We understand that you are planning to develop a mobile fitness product, but no one cannot assume that they understand your requirements better than TechnBrains . To create a successful product, you must identify your target audience and the devices they are most likely to use. 

You may discover that your users prefer to use your app on a tablet during the day and then switch to a TV or check their progress on their wrist in the evening. It’s essential to note that the user experience for home workouts and gym exercises should be significantly different.

At this stage, you must answer a few questions, such as:

– What unique selling proposition (USP) does your product offer?

– Which mobile and other platforms do you need to support?

– How do you envision people using the application?


When developing a fitness trainer app, it’s important to understand the different stages involved. While market research can be done independently, prototyping usually requires the help of an agency with relevant UX/UI expertise. The goal of prototyping is to transform your app idea into a tangible form, namely a prototype. A prototype is an interactive representation of your application, which is tested and iterated with your test customers to ensure it meets its intended purpose and inspires positive feedback. The process involves creating a low-fidelity design, followed by a high-fidelity prototype, and then testing and iterating the solution until it’s ready for launch.


Now that you have a prototype that’s ready and verified, it’s time to move on to the next step. But why is it so crucial to spend time on selecting the right tech stack for your project? There are a couple of reasons. First, the choice you make will impact the budget for the development of your custom health and fitness app. Second, different tech stacks may impose certain limitations on the capabilities of your mobile product. So, what are some of the technologies that we can choose from when building a workout app?

Native apps

Native apps are built with Swift and Java/Kotlin. They have full access to all platform hardware, but they typically take longer to produce. For example, Apple Fitness+ (once it’s available) will face fierce competition in the home fitness market.

Cross-platform app 

On the other hand, cross-platform app frameworks like React Native, Flutter, and Kotlin Multiplatform allow developers to create fitness apps for both iOS and Android simultaneously, reusing much of the code. This results in a faster time-to-market and a more manageable budget.


If you want to convert an existing web application to mobile or start with a small project that doesn’t require connection to external or platform hardware, a progressive web app can be a great option. However, it may not be the best choice for creating a gym app or any other fitness application.


You can use no-code tools such as Appy Pie to create your own fitness app, but use it at your own risk.


We have reached the coding stage, where we will prepare sprints with tasks, carry out testing, report to you on progress, and receive feedback from you. We understand that developing a personal trainer app may seem like a complicated process, but we strive to make it transparent by keeping you informed of its progress via email, Slack, and regular video meetings.

An essential part of this stage is quality assurance after each iteration to ensure that new features work correctly. Together, we will address questions such as how to maintain the scope while simultaneously reducing development costs. We can achieve this by reusing off-the-shelf components for barcode scanning, charts, food data, and any other features that you envisaged. Additionally, we can opt for React Native or PWA (when possible).

Where can we integrate? Starting with sensors, Apple Health, Google Fit, and Samsung Health is a good idea. For mobile solutions, Endomondo, Fitbit, etc. are good options, with relevant user data.

How will we test the application?

For software testing, we can use peer code review and both manual and automated testing with tools like or Crashlytics.

Do I need to worry about HIPAA compliance?

 Fitness applications typically do not transmit protected health data (PHI), so HIPAA compliance is not required. 

How to make a fitness app more secure?

Adding biometric authentication such as Face ID or Touch ID should be sufficient. Social logins may also be used. In the end, this would provide us with a fitness and wellness app.


We have reached the stage where we can finally launch our app on the mobile stores. However, our work doesn’t end there if we want to expand our product. To achieve growth, we will need to take the following steps:

  • – Use a built-in mobile analytics tool (such as Google Analytics or Flurry) to monitor application usage.
  • – Keep an eye on user reviews and in-app feedback via email or a built-in customer feedback tool.
  • – Continuously update our solution by adding new features and making changes to existing ones based on user feedback.

This process is ongoing as our user base will continue to grow, and our gym workout tracker will keep evolving.

How Much Does It Cost to Build a Fitness App

Developing an MVP (minimal viable product) for a basic healthcare app may cost around $25,000-$30,000. On the other hand, if we consider a full-featured fitness product, the app development costs may range from $60,000 to $160,000. This cost may vary depending on the implementation of additional features such as AI/ML technology to recognize user movements during exercises, the need to support BLE and various hardware connectivity, and the inclusion of voice integration and video streaming.

Monetization Strategies

Fitness apps use the same app monetization models as other mobile software. They can be sold through in-app purchases or subscriptions. Alternatively, an e-commerce store can be set up if there are concrete sports equipment or food items to sell. Lastly, a fitness app can be created just for the sake of having a great app and building a loyal fan base.

If a subscription model is preferred for a personal training app, it’s best to keep it outside of the app, at least initially. This way, the 30% cut that Apple and Google take from each purchase can be avoided.

Subscriptions are recommended as a business model for personal training apps as it is widely used by the top 5 reviewed apps. However, ads can also be considered, but it’s important to be cautious not to harm the user experience and maintain consistency.

Fitness App Development Best Practices

We have extensive experience in developing fitness mobile apps and would like to share some tips to make your app stand out. One recommendation is to test the application from a usability perspective. This means having users from your target group consistently train with the app during the development phase. They can provide valuable feedback on issues that your quality assurance team may miss, like the need for longer pauses between sets. 

Another suggestion is to build a community by allowing users to share their meals and follow each other. You could also consider integrating with Siri and Google Assistant to enable voice control, and adding gamification elements inspired by apps like Zombies, Run! Additionally, deploying CDN tools would help to smooth out interactions with videos and imagery. 

It’s important to seriously consider the UI aesthetics as well. For example, an overweight person may not enjoy using an app with sports models on every screen.
