How To Create A Fitness App: 6 Steps

Step 1. Research your market

The first step is to study your target fitness app market and decide what type of app to build. Before starting development, you need to identify your competitors, understand their strong and weak points, and see how they solve user problems. Use this information to analyze the market thoroughly and choose which type of app to create.

Step 2. Decide on the app’s monetization model, platform, and features

After understanding the market, choose whether to launch on iOS or Android. If most of your target users are on Android, start with a basic version (MVP) there and consider iOS later. While having your app on both platforms costs more, it helps reach more users and can be worth the investment.

Next, plan how your app will make money. You can pick from various strategies or combine different approaches that work well together.

You now understand what basic features a fitness app needs. But to stand out, do more research and test extra features based on your app’s purpose and what your users want. These additional features could be what makes users choose your app over others.

Step 3. Prototype and user testing

The best way to check if your app idea will work is to create a basic version first (MVP). This version only needs the most important features.

Next, let a group of your target users try out this basic version. Get their feedback and note what changes are needed. This early testing helps you understand how users interact with your app and helps avoid costly changes later during development.

Step 4. Choose your tech stack

Once your solution gets approved, you need to pick the right technology for your workout app. This choice affects how much your fitness app development will cost. It also determines what your app can and cannot do.

Here are the main technology options for building a fitness app:

• Native app: These apps are built using Swift (for iOS) or Java/Kotlin (for Android). Since these programming languages are made for specific platforms, the apps can use all device features and work very smoothly.
• Cross-platform: While native apps work great, they take longer to build and cost more. If you want your app to work on multiple platforms at once, you can use tools like React Native, Flutter, or Kotlin Multiplatform.
• Progressive web app (PWA): This is a special type of web app that works on any device, both as a website and mobile app. It’s a good choice if you want to start small and don’t need to connect to device hardware.
• No-code/low code: Some tools let you create fitness apps without knowing how to code. However, apps made this way have limited features and might not give users the best experience.

Step 5. Develop, test and repeat

During this step, developers build the app according to the approved plans. This includes creating both the frontend (what users see and interact with) and backend (how data is processed, stored, and kept secure).

A big part of development time goes into testing and fixing problems. Quality assurance teams check the entire user experience, make sure features work correctly, and look for any bugs in the code.

Step 6. Launch and maintain your app

When you reach the final stage, your custom fitness app is ready to be published on app marketplaces.

However, your job isn’t done after launch. You need to watch how your app performs and fix any problems that come up during use. You can track your app’s performance using tools like Google Analytics and Mixpanel to spot and solve issues quickly.

To make your app successful and profitable, you also need good marketing and customer support. Share your app on different platforms, keep your training materials current, and pay attention to what users say about your app.

Essential Features In A Fitness App

Every fitness app has its own purpose and helps users in different ways. But there are some basic features that every good workout app should have to make it easy and helpful for users.

• Sign up/Log in: Users should be able to make their own account and sign in using their app details or other accounts like email and Facebook.
• User profile: Once users have an account, they enter their health details and fitness goals. This helps the app suggest the right fitness plan for them. The more information users share, the better advice they get.
• Third-Party Device Connectivity: Today’s fitness apps need to work with more than just phones. With devices like the Apple Watch becoming popular, apps must connect with other smart wearables. These third-party devices are now a must-have feature for workout apps. Wearable fitness technology helps apps collect user information and stay connected with users.
• Blog or diaries: This feature can be used as a food diary (for tracking meals) or a blog (for sharing workout tips and health advice). People who use fitness apps usually care about their health and lifestyle. A blog helps you share useful information with users, build your brand, and keep users coming back.
• Social media sharing: Adding social media features to your app is smart for many reasons. When users share their progress with friends and family, they feel more motivated and inspire others to get healthy. This also helps you get new users through word-of-mouth.
• App integration: Since phones like iPhones and Samsung devices have their own health app, your app should work well with these built-in apps to share data easily.
• Notifications & reminders: If you want users to keep using your app regularly, this feature is crucial. Sending them reminders (for workouts, entering data, etc.) encourages them to open and use your app more often.

To make your app better than others and give users a great experience, think about adding these extra features.

• Heart rate tools integration
• Motivational goal tree
• Game elements
• App community
• Competition or practice-together mode

Monetization Strategies For Fitness Apps

Looking at the numbers, the fitness app market shows great promise, with many apps making good money in recent years. If you want similar success, you need to know how to create a fitness app that brings in revenue.

• Subscription: Users need to pay to use your fitness app’s features. One good way is to offer a free trial period. If users find your app helpful, they’re likely to pay or subscribe to keep using it.
• In-app purchases: Give users basic features for free, but charge for advanced options. This could include extra workout programs or talks with fitness experts.
• Advertisements: You can make money by putting ads in your fitness app. But be careful about how many ads you show, where you put them, and how long they run so users don’t get frustrated.
• Fees: Another way is to work with online fitness coaches through your app. When users sign up for training programs on your platform, you can charge a fee.

How Much Does It Cost To Build A Fitness App?

The cost changes based on many things, like what platforms you want to use, what technology you need, how complex your app is, and where your development team is located.

Your app development team figures out how many hours they’ll need to work, which helps set the total fitness app development cost. Usually, it takes 4-6 months to build a medium-complexity fitness app.

If developers charge $50 per hour, making a full-featured fitness app could cost between $60,000 and $160,000.
