Post-pandemic pursuit of a healthy lifestyle

The COVID-19 pandemic made us pay more attention to our health. People avoided crowded places and preferred workout apps over gyms. Fitness tracking app users had a great chance to stay home and train just as effectively — this was a perfect match for the changed lifestyle.

A workout app is an easy and affordable way to maintain wellness from almost anywhere.

Increasing use of gadgets

Today, smart devices are accessible and affordable. Smartphones are leading the way, and most fitness tracking apps are installed on mobile devices. By 2030, we will see an increase in the use of fitness apps through wearable devices, but smartphones will still stand out from the competition.

Increasing time spent in apps

According to statistics, 42% of users open their health and fitness apps at least once a day. They believe workout applications and fitness trackers help them achieve their health goals. We can assume that the time spent on fitness apps will only increase as the tech develops.

Apps are part of the gym’s ecosystems

Gyms and sports clubs added mobile apps into their business model. Fitness trackers help to increase the gym’s clients’ loyalty by providing workout history, saving users’ data, and drawing useful graphs and progress bars.

The fitness tracking app market

Fitness apps differ in their logic and features. Workout apps teach users to do their exercises correctly, often providing audio and video guidance and synchronization with wearable devices. Diet and nutrition apps help you track eating habits, set and monitor calorie goals, and find healthy meal planning recipes. Nutrition apps and diet apps help users lose weight in a more interesting and engaging way.

Activity tracking apps, as the name implies, keep track of health indicators and different activities or exercises.

Some trackers are designed specifically for runners or cyclists, some for professional athletes. But most activity tracking apps are suitable for everyone. 

Tracking apps count the number of steps taken and the distance traveled, as well as measure your heart rate and other metrics. You can set goals and view your progress, always having a complete picture of your health condition saved on your device. The progress tracking feature is of great help when you are on your way to losing weight.

The fitness app market is experiencing incredible growth, and it affects all types of fitness apps. We’re expecting to see 4x growth of fitness activity trackers by the year 2026 in the U.S. The trend can be applied worldwide.

How to create a fitness app in 5 steps

The app development process, no matter what type of app it is, generally looks like this: Market research ➡️ Defining platforms ➡️ Choosing features ➡️ UI/UX design ➡️ App development ➡️ QA testing ➡️ Release ➡️ Maintenance. We thoroughly discussed all stages of developing all kinds of apps here.

Fitness app developers follow approximately the same path. Now let’s explore the tracking app niche precisely. How do you actually build a fitness tracker application?

Step 1. Do market research and plan

Fitness application development starts with an idea. But without a clearly defined plan and proper market research, all your fitness app ideas will not become a reality. 

Planning must take as much time and effort as the entire development process to bring real results.

First, determine the specific demographic and user segments you want to target with your fitness tracker app. Then, study existing fitness activity trackers in the market to understand their features, user experience, and strengths and weaknesses. Identify opportunities that your app can capitalize on.

How to choose a target audience for your fitness tracker app

Determine the target demographic and user segments

After that, develop a monetization model to decide how you will generate revenue from your app. Options include in-app purchases, subscription models, ads, or a combination of these. Lastly, ensure that you meet the legal and regulatory requirements related to fitness and health apps in your target market. This may include compliance with data privacy laws and regulations.

Step 2. Define your platforms

What devices does your target audience use? Of course, smartphones have become an extension of our hands, but when you are about to create a fitness app you have to see the full picture. Ask your potential clients if their physical activity is measured by smartwatches, wristbands, pedometers, or other tracking devices. Do athletes watch fitness videos provided by your app on TV? Maybe they are used to switching from smartphone to tablet when they come home and expect all data to be synchronized without delay.

Analyzing your audience’s behavior will help you to make a fitness tracker app that meets all expectations. An app will become indispensable if it is linked to other software the customer is using and follows their activities on all preferable devices.

Step 3. Choose principal functions

The idea to create a fitness app should be helping users achieve their fitness goals. They need to see their progress, track calories burned, stay motivated, and stick to the training routine. 

The critical feature of a fitness app is a well-functioning data processing algorithm that gathers all activity metrics from the device’s sensors. 

We can also add a desktop version and integration with basic utilities such as a calendar, a GPS tracker, and a music library. app screenshots app

Depending on your target audience, you’ll have to implement additional features to develop a fitness tracker app that meets the users’ demands. For example, you can add sleep tracking and mental or emotional state tracking features — or maybe you’d like to add more gamification elements to engage your users. And remember that any feature you choose should benefit the end user in some way.

Step 4. User-friendly design

Even if your workout application has a bunch of useful features, there is always the main one — the reason athletes choose your tracker and not another app. User-friendly design for a fitness app directly affects the UX and determines whether users will like the app or abandon it. Maybe the first thing users need when they open an app is to check their water consumption, set a timer for an exercise, or view yesterday’s number of steps before setting today’s goal. 

Make it easy to navigate and edit user profiles — app users should be able to access everything they might want in just 1-3 taps.

A couple more tips: maintain consistency in terms of design elements, such as colors, fonts, buttons, and icons, throughout the app. It helps users feel comfortable. Use legible fonts and appropriate font sizes. Ensure that the text is easy to read. Keep the interface clean and focus on the core features and information users need most.

All that is pleasing to the eye and easy to use are light and aerial interfaces. Do not overload the user with your design delights – everyone already knows that UI / UX studios can execute cool things. It is better to be user-friendly and use pastel colors and light backgrounds.

Step 5. Develop interactivity

Examples of successful fitness tracking apps show that interactivity is key to creating a fitness app that motivates users and earns their loyalty. In the stage of fitness app development, pay special attention to the gamification and social features of the app. The afore mentioned Strava app, for example, lets you virtually compete with users from the same area and earn rewards while climbing the leaderboard. And in FitBit you can set up a family group chat and start a walking challenge.

Your audience will be better engaged in tracking their progress and health routines if your app incorporates interactive features such as ratings, reward systems, stickers, and colorful stats. People are motivated by earning badges and certificates and sharing these achievements.

Step 6. Release an MVP and get feedback 

MVP — Minimum Viable Product — the first version of your app. You’ve gone through all the stages of the fitness app development process and are ready to release a working fitness tracker. 

How can the MVP approach help make a fitness tracker app that is both effective and reasonably priced? The answer is — get feedback. An MVP can help you gather valuable user feedback before spending the entire budget on a product that doesn’t meet customer expectations. It helps you to implement additional features that were previously overlooked or enhance the functionality of existing ones.

The next you can do is check feasibility. Entrepreneurs are not programmers. Business owners can plan app functionality that is impossible to bring to life from the development perspective. MVP helps to test vital app functions, its scalability and algorithm realization, at the same time being a perfectly working application.

Step 7. Maintain and update your app

Regular maintenance involves monitoring for performance issues and security updates to keep the app running smoothly. Updating the app allows you to introduce new features and improvements that react to user feedback.

Consider scaling if you realize that there’s a market demand for additional features. For example, people are downloading more diet and nutrition apps, and they fit into your original concept. But even if everything is fine and you don’t want to change anything, be sure to maintain your app to fix bugs, speed it up, and adjust it to operating system updates.

Tech Stack

To develop a fitness tracking application, you’ll need to think about the technical stack. It’s a set of tools that are used for the creation of the app. It can also influence the cost of developing the app. At Purrweb, after going through various options, we settled on JavaScript frameworks. The choice turned out to be good, as we have successfully launched 300+ projects using this tech stack.

Back-end Node.js, JavaScript Gives developers a scalable and efficient backend architecture.
Front-end React Native, React.js, Electron.js React Native allows you to save about 30% on cross-platform mobile app development. React.js and Electron.js speed up and simplify web and desktop app development.
Infrastructure AWS, Heroku The scalable infrastructure allows the application to be hosted and provides many useful features such as autoscaling and continuous integration.
Database PostgreSQL, MySQL, Redis Combining different databases allows you to store data and maximize its protection.

How much does it cost to make a fitness app?

Here’s Purrweb’s health and fitness app development cost breakdown. Bear in mind that these are approximate numbers — we based them on our calculation of a fitness app that has basic functionality. 

Stage Estimation in weeks Approximate costs
Project analysis $1,000
UI/UX design $5,400
App development  9 – 10  $36,000 – $40,500
QA (Quality Assurance)  concurrently with the development $5,400 – $6,000
Project management during the whole project $3,950 – $4,100

Overall, you will need approximately $56,000 to create your own basic functionality app, and the application development process will take 920–1020 hours, or around 4 months.

Depending on the number of innovations, the staff involved, and the desired functionality, the app development cost can be lower or higher. Check out our article to get additional information about how much it costs to develop an app.

Monetization strategies for a fitness application

Most of the famous fitness trackers are free in their main functions. However, it doesn’t mean that they are not making money. Let’s see what monetization strategies can help you meet all user needs while earning money.

Subscription. Your app can have different levels of subscription, starting from a free trial and increasing based on the needs of the athletes. Your subscription fee may vary depending on the number of features a user gets or depending on the time they are planning to spend on your app.

In-app purchases. When the audience is loyal and has a strong commitment to your services, they might want to boost their experience with in-app purchases. That can be additional features, such as access to video lessons or personalized training plans, as well as little one-time purchases — certificates, stickers, avatars. 

Ads. An easy way to make money on the app is by allowing other brands’ to publish advertisements on your fitness tracker. Keep the amount of ads reasonable and make sure that users are not irritated. Ads should be thoughtful and match your brand style and niche. 

Scaling. The most complex of monetization strategies is building an ecosystem around your brand.If you have other offline and online products and services, make sure the audience is aware and is willing to use your entire product line to enhance their experience.
