How to build a fitness web app – no coding needed

Staying consistent with workouts can be challenging. Tracking my progress manually felt like a chore, and most fitness apps such as Strava or Fitbit were either too complicated or packed with features I didn’t need.

I wanted a simple, distraction-free way to log workouts, set goals, and monitor progress without dealing with unnecessary clutter or subscription fees. So, instead of searching for the perfect app, I decided to build my own.

Normally, developing an app like this would require coding skills, a database, and a lot of setup. But with Hostinger Horizons, I could build a fully functional custom fitness web app without writing a single line of code.

In this guide, I’ll walk you through how I created my fitness web application – from planning and design to deployment and testing – so you can build your own in minutes.

Fitness web app planning and design

Before jumping into the build, I outlined what I wanted my app to do:

✅ A simple dashboard where users can log workouts (where I can save my exercises, sets, reps, and duration).

✅ A goal-setting feature to track progress.

✅ A way to generate workout summaries based on past activity.

✅ An intuitive user interface that makes logging workouts quick and easy.

I didn’t want to spend weeks coding or worrying about technical setup, so I used Hostinger Horizons to design my app. Here’s why:

• No coding required. I can just describe the app I want to create, and AI will generate it.
• Instant updates. Refine features, improve UI, and fix bugs in real time.
• One-click publishing. Once the app is ready, it can go live immediately.

Getting started is simple: Hostinger Horizons includes a free plan (5 messages/day) to start developing your web app. You can also purchase a Hostinger Horizons plan to unlock more credits. The starter plan, starting at $19.99/month, gives you 100 messages/month.

How I created a fitness web application with Hostinger Horizons

With my plan purchased, it was time to start building my fitness web app.

Step 1: Setting up the project

To start, I went to hPanel → Websites → Websites list → Add website → Hostinger Horizons. This opened the project’s start screen, where I described my app idea.

Prompt example:

Create a fitness web app where users can log workouts, track progress, and set fitness goals. The app should have a simple dashboard for tracking exercises, sets, reps, and duration.

The tool instantly generated a basic interface with a workout log and a goal-tracking section.

Step 2: Refining the app logic

The first version worked, but I needed to refine it before launching. This helped me avoid common mistakes first-time web app builders make.

Key improvements I made:

✅ Added a goal-setting feature. Users can now set weekly and monthly workout targets.

✅ Improved UI layout. Adjusted button placements and color schemes for a better experience.

✅ Workout history tracking. Enabled users to view past workout logs.

✅ Optimized progress summaries. The app now generates weekly summaries based on logged workouts.

Prompt example:

Improve the UI by making the workout entry fields more structured and adding a visual progress bar for goal tracking.

The AI quickly made the adjustments, giving my app a cleaner look and a more intuitive interface:

I also wanted to experiment with a more minimalistic, menu-driven layout:

Step 3: Testing and debugging

Once my app was functional, I followed key web app testing steps to ensure everything worked correctly.

I tested different scenarios, including:

• Logging multiple workouts in a day.
• Editing and deleting previous entries.
• Checking if progress tracking is updated correctly.

When I found a small glitch with a blue line appearing in the middle of the screen, I asked the tool to fix it.

Troubleshooting prompt example:

There's a blue line in the middle of the screen. Can you please get rid of it?

The AI analyzed the issue and provided a quick fix, explaining what it had done:

Fitness web app deployment

After refining my app, I published it with one click from the editor. Now, it was live and ready to use:

To give my app a custom domain, I connected it directly through Hostinger Horizons. You can also manage domains through hPanel → Websites list.

I can also easily tweak features anytime since the tool lets me edit the app after publishing. For example, after a few days, I realized I needed a personalized workout suggestion feature. Instead of building a new app from scratch, I simply entered:

Prompt example:

Add a feature that suggests workouts based on past logged exercises and goals.

Within seconds, Hostinger Horizons updated my app with AI-generated workout recommendations tailored to user history.

Using my app in real-world scenarios helped me make more

improvements to my fitness routine. If you want to try my fitness tracker, feel free to test it out!

Conclusion

I now use this app every day to log my workouts and track my progress, and I can quickly add new features whenever I need them. This app will allow me to replace my gym membership with my app-based workout, and I know there’s a growing population of people around the world following the same trend. In fact, 60% of fitness app users report making the switch from gym memberships to app-based workouts. I think being able to tailor your own fitness app experience is a complete game-changer.
