The Most Successful Fitness Tracker Apps

Features of a Fitness Tracker Application that Bring Profits

Before thinking about how to make a fitness tracking app, let’s see what features are in demand nowadays. After all, you have to launch something your target audience needs, so it makes sense to look into that. 


Allow to fill in a personal profile for everyone. Name, age, gender, and preferred workout type alone will give you lots of info to show targeted ads or the most fitting training. This feature may also help you estimate the number of calories lost during the workout or running session.

Push notifications

Push notifications have to be personalized as much as possible, depending on the most used features, set bodybuilding goals, progress, and even suitable deals from your eStore.

fitness tracking app should contain push notifications


Various trackers for nutrition, fitness, and overall progress make these apps even more personalized and engaging. You can send notifications to the users when they reach a new milestone to remind them to use the app more often.


With user consent, of course, offer geolocation tracking so that they can see where they ran or went and how long the distance was. Offer the best places for working out, the ability to build routes beforehand, etc.


Make fitness fun with some gamification, like rewards for running or walking a certain number of miles. The rewards can be discounts for your eStore items or points that can be later exchanged for a week or a Premium plan.

Other notable mentions are social login and sharing, wearables synchronization, setting goals, and sleep tracking.

OK, with the list of features you can use for the program, we can proceed to see how to build a fitness tracking app.

Stages of Fitness Tracker App Development

So, how to make a fitness app? What steps do you have to know about? How to make sure you don’t miss out on anything? ProCoders has a neat step-by-step guide on how to develop a fitness tracker app.

Step 1: Research the market and create a concept

Thorough market research shows you:

  • What the audience expects from similar products
  • What your direct and indirect competition is
  • What niche is the most popular nowadays, and more.

All this helps you see how to create a fitness tracker app that meets users’ expectations. With this in mind, you have to create a concept where you’ll have info on design, features, messaging, etc.

Step 2: Choose the features you want for the fitness app

Some entrepreneurs want to launch a really useful app so badly that they stuff it with features right away. First of all, it’s going to confuse people and the fitness tracker app you’ve started won’t have one clear goal you can market. Besides, more features mean more developers and/or more working hours, which also makes the price skyrocket.

So, it’s better to position your app in a niche where it can be useful (that’s what we’ve done all that market research for).

Step 3: Design the interface with UX in mind

An intuitive interface makes a difference. Hiring a designer with experience in the Health & Wellness industry will ensure that your idea finds the right way into the real application. You’ll have to pick colors, buttons location, menu, profile design, font, its size, etc.

All that should not decrease loading speed and other user experience metrics, so there’s a lot to think about.

An expert can help you make the right choice so the app reflects what you wanted to launch and suits your target audience.


Step 4: Develop a prototype and an MVP

A prototype will help you see how your app may look after development and testing. It’s suitable for first presentations when you’re looking for sponsors or researching the target audience.

An MVP or a minimum viable product is a working version of your program with basic features like registration, a workout or two, and progress tracking. You can pitch it to potential investors or even launch as a beta version to get the first reviews and revenue.

Step 5: Build a fitness tracker app and test it

Hiring the right people with the proper skills is essential for this step. If you don’t already have a team or need additional staff, make sure to turn to ProCoders. We’ll find the experts who will bring value to your app and use their skills and experience to make it as good as it can be.

The building of the program will consist of frontend and backend development. After compiling the two, it’s absolutely crucial to test the application. For that, a specialist uses a combination of manual and automatic tests.

ProCoders highly recommends hiring QA specialists instead of trusting the testing to developers. Qualified pros know what software to use and what types of assurance your product needs.

Step 6: Launch, gather feedback, and consider improvements

The final step is to launch the product and execute your marketing efforts. It’s important to gather initial feedback to see where the app may need improvement and make changes to the new version.

And there you go!

Tech Stack You Need to Build a Fitness Tracker App

Another important topic is the tech stack your developers need for a fitness tracking app start.

  • SDKs for wearables integration – Fitbit, Misfit, Nike+, etc.
  • APIs and SDKs for tracking data – Google Fit or Apple’s HealthKit
  • Running features – Tomtom
  • Barcode scanning – Nutritionix API, Open Food Facts
  • BMI calculator API – written in PHP, Node, .NET, Java Ruby, etc.

FAQ. Here is even more information on the topic of the development of your fitness tracker app
How much does it cost to create your own fitness tracker app?

$60-80K or more if we’re talking about a full-on fitness tracking mobile app development from scratch. The final number depends on a lot of things, including the kind of app you want, how fast you want it, and how many people you already have on board.

Which factors influence the fitness tracking app development cost?
  • The scale of your app, cross-platform or native development, the time you have, their level of expertise (junior, middle, or senior)

If you’re not sure about any of those things, we can’t provide you with a clear estimate. But ProCoders Discovery Phase can! Provide us with the information about your idea, budget, time expectations, etc., and our analysts will come up with the most optimal plan and numbers for your situation.

How to monetize your fitness tracking app?

You can provide paid materials, subscriptions, paid advertisements, and an online store.

  • Paid materials – special workouts, health and wellness webinars by top experts, meal plans, etc. will come in handy for the users and bring extra revenue for you.
  • Subscriptions – it can be one Premium subscription or several plans for any budget. You can also have a free plan with relevant ads and limited access to workouts or other special features.
  • Paid ads – relevant advertisements won’t stain the quality of the experience and will earn you extra something.
  • eStore – selling physical goods like yoga mats, sportswear, dumbbells, etc. will increase revenue and make customer experience more wholesome.
What tips are there to save on cost to create a fitness tracking app?

Focusing on essential features, building a cross-platform app instead of two separate ones for iOS and Android, and hiring remote staff for the job are some things you can do to save money on developing a fitness tracker application.

You can add more features when the program starts bringing money. And hiring additional staff or a whole team via a staff augmentation company like ProCoders will ensure you get a high-quality product without overpaying for an in-house team (or additional full-time staff for an existing team).


Starting a fitness tracking app can be difficult, but once you research the market and make your positioning clear (what app you want to make, how it’s going to be useful, what the target audience is), it becomes much easier.

By including the features like profile personalization, geolocation tracking, nutrition and workout plans, and progress tracking, you’re going to have a very promising product.

As to the technical part, ProCoders can help you with it by finding top-notch professionals with the necessary tech stack knowledge and experience. We’ve already helped develop fitness apps, so be confident to apply to our Discovery Phase to discuss your idea!
