A Brief Introduction – On Demand Fitness Training App

We all have heard the saying “All work and no play makes Jack a dull boy”. It turns out that we have many “Jacks” around us who work for nine to ten hours a day at the office and travel for another three hours back and forth per day. Our lives have become so robotic, monotonous and hectic that even the thought of joining the gym or going out for a run at the park in the morning gives us chills! Fast foods and beverages have become our staple food.

We are accumulating in a whole lot of calories and carbohydrates on a daily basis but we are not burning even one-tenth of what we are consuming. This is where health and fitness mobile applications come into play to reinvigorate our workout & diet-nutrition plans thus entrepreneurs who have a knack in the field of fitness are implementing their ideas and investing in this multi-million dollar business by developing a fitness smartphone app.

Understand the basics of on-demand fitness training app – Analysis

Every entrepreneurial venture starts with an idea and a vision. The App developer  first needs to define an end goal & target audience of the App, what will the application measure and which functionality is required. The fitness world is a diversified field – it includes weight loss, muscle building, diet & nutrition, and much more, so App developer needs to delve deeper into the subject.

An App developer needs to focus on the practical applications of the app. At first, there should be a collaboration with different gym trainers, fitness experts, and dieticians. List down all the aspects that the app is going to cover in its initial stage. Registration should be done at both the customers as well as at the expert’s end.

Health & Fitness Mobile App Developer

At the user’s end, they will have to log into the app to keep a record and synchronize their daily workout activities. It is better to develop the app’s UI as simple as possible. Categorize all the sections of fitness and exercises that the app will be providing, neatly under a drop-down menu.

The fitness app can have different sections for fitness, yoga, and diet. The app developer should also be aware of all major competitors in this field of fitness app business. Ensure that the app design and features are slightly different from them, if not unique.

Categorizations of Health & Fitness Mobile Application

Let us take a deeper look at the various categories available in this field. One either can create an app specializing on any of these broad categories or can also make a combination.

Health & Fitness Mobile App Development

Exercise apps / Workout apps

Due to the hectic daily schedule, it is very difficult for us to visit a gym every day. This is where health and fitness apps comes in handy. The app will do the work of a personal workout trainer in customer’s smart phone. The user logs into the app and gets the information about the preset weight loss regime or muscle build-up exercises. They will be guided with various visual demonstrations on how to do the workout in a proper manner. This application also has an online notebook wherein the user can schedule and plan out their weight loss target and save all their personal workout sessions in order to track their progress.

 Physical Activities Tracking Apps

The fitness application tracks all the physical activities a person does during the day, like walking, running, jogging, exercising and even sleeping. The app uses the motion sensors in the user’s smartphone and with their GPS turned on, it provides accurate data on the number of stairs climbed, liquid intake, steps or kilometers walked or ran, calories burned and hours slept. This app also lets the users set their own personalized fitness goals and weight loss plans.

Yoga applications

These applications provide directions of how to do different yoga postures through visual demonstration. Some apps are even designed for specific asana whereas others offer a full set of exercises.

Diet planning apps

Apps providing diet plans keep a track of the user’s sugar and calorie level, water intakes, choice of appropriate food dishes and a control over their food habits. The applications are highly motivating for the users to find it easy to stick to their diet plans and give special rewards for achieving a specific goal.

App’s basic features package (The User Side)

With the app developer having some basic knowledge of fitness app, he has to choose the right features in the application. Some of the basic “must-have” features for developing fitness app include:

Registration / Logging in-

After the app is successfully installed on users’ smartphones, they need to register via their e-mail, Facebook or by an OTP confirmation on the users’ mobile number.

Editable user profile with personal info

Upon successfully registering, the user will have to fill in their profile details that will include their name, age, sex, height, weight, and other vital details. This will help the app know the current physical state of the user.

The users will have the option of linking up their social media accounts with the app. The integration of their Facebook, Twitter, and Instagram accounts will enable users to share their achievements and their fitness goals accomplishments with their friends, family, and associates.

Multi-device synchronization

With the help of Bluetooth, GPS, and motion sensors, the app should be able to sync with other tablets, personal computers and wearable gadgets like smartwatch or a Fitbit wristband. The multi-device sync facility will make it even more convenient for the users to track their records from any device they want.

Health & Fitness App -Wearable Device Integration

Option to set various tasks

Along with preset fitness goals, the user will also have the freedom to set their own personalized tasks and goals to achieve within a given time.

The cloud sync feature will help in saving all the statistics of the user in the journal so that they can track their progress regularly.

Preset exercise, meal-plan

Based on the details filled up by the user, various workout plans will be pre-scheduled for them. These workouts will generally be a visual demonstration showing exactly how each exercise needs to be done in a proper manner.

Activity Log Tracking

Log tracking enables the users to keep a track of their day-to-day workouts, walks, and other physical activities.

Activities Log

VR fitness Experience

Users can workout in groups or with a personal trainer without actually leaving their apartments.

VR Fitness App Development

E-commerce options

E-commerce options to make some purchases for a workout process or other activities. This is an optional feature but adding this may increase the interactivity, along with opening new doors of monetization for the app owner.

Geolocation integration

The user should be granted permission for the app to use their smartphone’s GPS for real-time tracking. Geolocation integration feature will give accurate information regarding the steps walked, kilometers ran, and even the number of hours slept.


Although most of the services in Health and  fitness app are free of cost, there will be certain premium features that users can enjoy by paying a small monthly subscription fee. Having multiple payment options, such as Credit/Debit Cards, eWallets, NetBanking etc. enables users to choose the suitable mode of payment.

Native Push Notifications for Results Display

The app will provide push notifications on the accomplishment of daily, weekly and monthly goals. It will also provide the user an option to share their achievements on their social media.

Health & Fitness App Development – Admin Side Features

The App development firm needs to partner with a couple of gym trainers, fitness equipment and supplement wholesalers, and dieticians so that the app developer can provide live updates and conduct live sessions with the users of the app and the fitness experts. For this, they also have to go through a regular registration and login process from the app itself.


The clients will be directed to the dashboard in the app after they log in. On the dashboard, they can keep a track of all the live sessions, chat sessions they have had with the users and can see the detailed orders placed by the users for various gym equipment or supplements and the delivery date.

Accounts section

In this section, the clients can view their past deliveries, customer reviews, and account balance.

Payment Section

In this section, the clients will have the option to make their payments to Gym-owners, trainers and individuals via wallet App or transfer the money to the bank directly as well.

Marketing & Promotion Tools

Loyalty Programs, Cashbacks and referral programs remain the backbone of marketing for such apps. Admin may also choose to enable other marketing options like Retargeting, Social Sharing, Push Notifications etc.

A Few Additional Tweaks – Additional Features of the Fitness App

In order to stand out from the crowd of fitness apps, the mobile app developer can incorporate a number of small features to the application including-

  • Collaborating with gym trainers or fitness experts and have a live session with them enabling customers to stay motivated and are updated about the latest trends in the world of fitness.
  • Enable chat and live streaming with fitness coaches for users so that they can get instant help and guidance in real-time.
  • Create a special music playlist for the app users wherein they can listen to their favorite workout songs and stay energized during their daily fitness regime.
  • Collaborate with dieticians or nutritionists and provide live sessions with them explaining the benefits of healthy eating and the fun way to eat natural food.

Health & Fitness Mobile App – Back-End Technologies

To make apps work and synchronize in both web and mobile platforms, the App Developer can make use of Cassandra, PostgreSQL and sometimes a general caching system of the memory. But it would be better to keep the main framework as Python and JavaScript. Some of the others tools which can lower the impact of complexities and the cost are:

  • To process and manage data in real time: Kafka Software
  • For storage or caching with CDN’s it is better to use Amazon S3
  • To integrate with Python services and model-based testing use GraphWalker.
  • For the primary platform structure, App Developer can take help of Google Cloud platforms or Dataproc.
  • For the desktop-based UI (CEF) Chromium embedded Framework is a better option.
  • One can also use Bootstrap for making it look classy and sleek for websites.
  • Nginx for HTTP and proxy server as it is an easy and open source.

The Backend is the most complex thing that needs strategic implementation. The architecture of the server-side is the clever part when it comes to building powerful apps that run seamlessly on each and every platform. Things may get tangled as there are many options available to choose from.

Health & Fitness App Development

Cloud Storage: Either we can use our own server or can use cloud storage servers like Amazon S3, Azure or Google Cloud Storage. Storage server plays an important role in media platform because it handles thousands of requests per second with superb efficiency.

Content Delivery Networks (CDNs): To better serve the user experience we need to use the highly scalable CDN services. So for that either we can configure our own server or we can use cloud server, like Amazon Cloud Front.

Digital Right Management (DRM): Standards to help you protect your content

Server Load Balancer: We can use the load balancer server to handle a large number of traffic or files request. For this, we can set up own server or can use Amazon Cloud Server to deploy the application and handle all things.

Video/audio Transcoding: In the backend process we need to transcode the media files in various media format to make supportable to all major browsers and devices. For that either we can use open source software like that FFMPEG or a third-party solution like that Amazon Elastic Transcoder.

One can also use PHP to some extent for server side, or the App Developer can choose JAVA. Other options it is better to include Clojure and HTML5 languages. Each task should be connected to the so-called “access point” to establish the link. Also, keep in mind if the concerned App Developer’s server is in the USA then the users’ located in China should not suffer from low bandwidth so it is recommended to take data centers in different places for better bandwidth.

Self Intuitive & User-Friendly UX/UI

Use minimal animations if required but make the app look visually appealing and smooth. The customers or users of the app should not get confused with the plethora of different options provided in the fitness app. It is better to keep the fitness simple, crisp and handy and in choosing the colors used for the app.

Team Structure

To make a superior application, you may need a mobile app development partner, a group of people who will make strategies, designs, development, and testing. Therefore, it is very important to choose right potential candidates and to evaluate them from time to time. Following are the key personnel those you should hire for sure-

Project Manager: He/she should be an expert on mobile industry having a precise knowledge of what works and what does not. You can perform the role as well provided you are confident of your existing knowledge and managerial skills. The project manager will make a deep market study and will suggest best things to do.

Developers – Developers are the real key movers and shakers who are creators of the app from scratch. A native app is much better than a web app. The team needs to have both Android Expert and iOS developers. They will be under the guidance of project managers. Now, it is important that you make an agreement with the team of developers so that they will provide technical support and will update the app from time to time against any bug fixing.

Designers- This group cannot also be ignored. No matter how strong your app may be regarding coding, if it fails to attract the view of users during the course of usage, it may soon be uninstalled. Therefore, good UX/UI designers are required to make a good choice of color, background, elements, etc. They make the frame look good on screen.

Testers- Testers are the certifiers. They are restless until they find a flaw in your app. Only when they test the app against every possible combination that they certify it as without errors, your app may mark its footprint in the application market. If the testing team is strong, the app will hardly need in updating against bug fixing in the near future.

Time Duration

The time duration could be anything between two to four months depending on the complexity and the size of the app.

  • Technical documentation (may take up to 40 hours of work)
  • UI/UX design (usually takes around 45-70 hours)
  • Front-end and Back-end development (the longest parts, takes up to 200 hours each)
  • MVP testing (around 80-100 hours)
  • Polishing and bug fixing (30-50 hours at best)

Cost of Health & Fitness App Development

Cost of developing a health & fitness app largely depends upon 3 factors – the complexity & size of the app, the number of platforms you want your app to run on and the country of development center. This is because different countries have their different hourly charges, for instance:

  • U.S. based developers: – $50 to $250 per hour
  • Eastern Europe based developers: – $30 to $150 per hour
  • India based developers: – $10 to $80 per hour

Below is the basic estimate in the ideal case (An average app with average features, developed for Android program and the center of development in India). Let’s break down the costs for different activities:

  • Technical documentation (40 hours – $1000 to $2000)
  • UI/UX design (60 Hours – $1500 to $3000)
  • Front-end and Back-end development (400 Hours – $10,000 to $ 20,000)
  • MVP testing (80 Hours – $2000 to $4000)
  • Polishing and bug fixing (40 hours – $1000 to $2000)

Adding-up all the costs, an average health & fitness app costs around $15,000 to $30,000 for a single platform (either iOS or Android). Choosing a cross-platform app or adding more features may raise the cost up to $50,000. However, spending around $50,000 guarantees your app to stand ahead in the competition.
