So, how can you get income from your app? There are several ways to make your app profitable. Let’s go through them.

Paid apps. Before accessing the app, users should pay for it. The price of an app is formed by its features and content it offers. The mobile iOS or Android platform of the workout app also affects its cost. iOS apps are more expensive. Therefore, the price of paid apps will vary respectively.

In-app advertisements. If you distribute your fitness application for free, you can suggest users buy items with your app. The offer includes a personal nutrition plan or healthy diet recipes based on users’ preferences and habits.

In-app purchases. This model implies that you offer your workout app partially for free. After gaining enough audience, you can provide premium experiences as in-app purchases. For example, in-app purchases may include personal coaching services or an add-free subscription.

Ads. Your app can bring profit if you cooperate with other fitness- or sports-related companies. Typically, the fitness application includes a cost-per-click or cost-per-mille commission. Also, you may include the ads of rewarded videos and rewarded surveys that give users points for certain activities.

Sponsored content. You can partner with fitness professionals and share their content in your app. Thus, users will gain expert information and advice on fitness through your solution.

5 steps when developing a fitness app: Codica’s practice

When it comes to fitness app development, we recommend going through a particular development process. It ensures that the app you create fits users’ needs and will be in demand. Let’s see what such steps are and how they help deliver a high-quality workout app.

Step 1. Product discovery

The product discovery phase is a step when you discuss your project with the workout app development team. At this stage, you describe the general idea of your fitness application to the team. In such a discussion, the team gets answers to a set of questions, including the following ones:

  • What are the business objectives of developing a fitness app?
  • What is the target audience that will use the workout app?
  • What are the competitor apps?
  • What is the project’s timeframe?
  • What is the budget for creating a fitness application?

Below is a short video that helps you learn more about the product discovery stage in web app development.

Based on the product discovery outcomes, the team plans how to create a fitness app. In particular, they plan your app’s features, architecture and design.

Step 2. Prototyping and user experience design

Prototypes are drafts representing the flow and structure of the app. They are necessary to show the arrangement of the app’s menus, fields, and buttons. As prototypes are clickable, you can see how your app will work during the fitness app development.

Prototypes are helpful as they simulate user interaction. Also, you can test them with users and make changes if necessary. Prototypes require less effort for development. So, making changes at this stage will be cheaper when you create a fitness app.

Step 3. Fitness app development

We recommend that our customers start the development process by creating a minimum viable product (MVP) first. There is a range of advantages in MVP app development services. In this version, the product holds basic features. So, it requires less effort for development and can be launched in the market earlier. Thus, you save time and cost of building a fitness application.

MVP is a workable presentation of a product. So, you can see how people use your product and what they would like to improve. Furthermore, such testing of the MVP in use shows the potential investors if your product will be in demand.

Our team uses JavaScript, Ruby on Rails and their frameworks to cover the front-end and back-end. Also, we include third-party integrations to ensure that the app is stable and secure.

We apply the best project management practices. Such an approach improves the team’s communication with a customer. Furthermore, it helps our project managers to optimize the development team’s work. The result of the joint work is a convenient and user-friendly product.

Developing a product, we move in iterations. This allows the development team and customer to see that the app development is moving in the right direction. If needed, the customer and the team can make the necessary changes at any stage.

Step 4. Quality assurance and optimization

After the product has been developed, we check and refine it to deliver the best result. That is why we thoroughly test the solution to make it work correctly.

Also, we perform code reviews and refactoring. This allows us to speed up and stabilize the solution work. Thus, we ensure the smooth running of the app.

Step 5. Support and maintenance

After the fitness app development, the team provides the customer with support and maintenance of the solution. This ensures that the workout app runs properly with different devices and operating systems.

At Codica, we use these stages in our mobile app development process. So, our customers receive tailored solutions that their users enjoy.

Basic features in fitness applications

There are three main types of information that fitness apps show:

  • Activity tracking;
  • Diet and nutrition;
  • Workout and exercises.

Based on these aspects, you can plan functionality for your solution. Let’s discuss in more detail what features are helpful to have in your fitness and workout app.

User profile

A user profile in workout apps typically includes the parameters that help personalize training. Users enter their body measures and age, activity level, and other parameters. This feature should also enable your users to enter the following data:

  • Weight goal;
  • Workout goal;
  • Nutrition preferences;
  • Progress dashboards.

Below is how a user profile looks in BetterMe, one of the top fitness apps. Each user profile item is changeable. You can edit your profile settings at any time. So, you always get the fitness plan that fits your current physical and daily life parameters.

Workout catalog

This is the core of any fitness app. You can deliver exercise videos, both live streaming, and available online on-demand. Also, you can include exercise images with voice explanations.

Since everyone has a different level of physical activity, the workout plans should correspond to them. So, it is advisable to include workouts starting with low and up to high impact. When you make a fitness app, provide your users with the ability to adjust, schedule, and plan workouts.

It is helpful for your users if you create a fitness app with the following points for this feature:

  • Time, equipment, and description for each exercise;
  • Easy switching between exercises;
  • Text-to-speech tool for voice tips with the support of many languages, like Google’s text-to-speech integration;
  • Workouts calendar or schedule dashboard.

Below is an example of exercises presented by a popular full-body workout app by VGFIT.

Maps with routes and geolocation

This is a necessary feature for the apps that track the users’ activities during running, cycling, or swimming. They can use it while the activity is in progress or after it is completed. It is helpful to include the following aspects in the routes when you create a fitness app:

  • Highlighting the points of the route that the user passed;
  • Point to the efficiency of the workout;
  • Providing data on the speed of movement and calories burned;
  • Weather forecast and air quality integrations.

For example, the RunGo app helps users create and share running routes with acquaintances.

You can help users apply the fitness solution more efficiently by sending notifications. They remind users of the workouts they need to do today or diet and nutrition plan. Also, you can notify users of the results they achieved today.

Notifications should encourage users to stay with the app. So, it is helpful to use motivational quotes and positive messages when making a fitness app. They will inspire users to train with the app more. Below is how the Six Pack in 30 Days app congratulates users on the finished workout.

Consider the following aspects for notifications in the fitness application development:

  • Notifications should be prompt and concise;
  • Include a log of notifications allowing users to keep track of their activities;
  • Enable users to manage and personalize notifications.

Nutrition plans and calorie counting

Nutrition is a vital part when it comes to keeping fit. The top applications offer calorie counters and meal plans to watch diet and nutrition. They also offer recipes based on the users’ fitness goals and preferences.

The nutrition planner enhances users’ experience by including the following options when you build a fitness app:

  • Bar code and food scanning allowing an instant count of calories;
  • Dynamic adjustment of recommended meals based on calories consumed and burned;
  • Tracking water intake.

Integration with audio streaming services

People like doing exercise or running to their favorite bits. Provide users with a smooth choice of songs. For this, you can integrate the solution with music streaming platforms, such as Apple Music or Spotify.

When you make a fitness app and add integration with the music service, the following is advisable:

  • Offer users the feature of creating and sharing playlists;
  • Let users choose the pieces that fit their workout tempo;
  • Bring up the tracks that helped users achieve better results.

Integration with educational materials

Educational content may include tips on diets and healthy lifestyle. Users can pick valuable recommendations that they can fit into their workout routine.

To make your users happy, consider the following aspects of fitness app development:

  • The content should relate to your users’ interests;
  • Offer concise audio, video, or blog pieces;
  • Customize the offered content to the users’ fitness results.

Including a content management system (CMS) that conveniently displays the materials in your app is also helpful.

Integration with wearable devices

Workout app development also includes integration with smart devices that give valuable statistics. These include smart watches, fitness trackers, and heart rate monitors. Such wearables help users see their results and keep track of their progress.

Leaderboards and social media sharing

Leaderboards and sharing their results on social media motivate people to achieve more. This is also how they can spread the word about your application. So, it is advisable to include these features when developing a fitness app.

Overview of Impact Fitness Application by Codica

How it started

Impact Personal Training is a fitness gym based in Luton, United Kingdom. The facility gathered professionals who create personal exercise and nutrition programs for clients. The gym aims to create an atmosphere that helps clients move at their pace.

During the spread of COVID-19, Impact’s clients could not attend the gym. So, the center decided to offer their clients a fitness app with the opportunity to stay fit while being at home.

Impact fitness app stats

The Impact fitness app includes 400+ exercises and 2000+ performed workouts. 400+ users downloaded this app on their mobile devices and desktops.

Solution delivered

Codica created the fitness app from scratch as an MVP (minimum viable product) with basic features. As the trainers and clients used the app, they started providing feedback to the Impact company on the desirable features.

Based on our expertise, we improved the app features upon users’ recommendations. As the app had more features added, we also optimized it to reduce server loads.

UX and UI design

We created the UX design and prototypes of the app in collaboration with Impact Personal Training. Trainers prefer desktops to assign tasks. Meanwhile, clients usually use mobile devices to track their fitness progress. With our UI/UX design services, we created UX prototypes for desktop and mobile versions of the solution.

UI design is a vital part of your fitness app. The graphic part creates the first impression for your users. Thus, UI design can define if users will like your app and whether they will use it longer.

For the Impact app, we chose a dark theme that resembles the design of the Impact sports gym. This part also includes the look of UI elements, such as colors, fonts, and icons.

Impact fitness app features

Desktop and mobile app

At Codica, we choose to develop apps as PWA (progressive web apps). There are several reasons for that. Let’s discover what they are.

A PWA is a solution that brings the full experience like the native apps but with more convenience for users. The PWA can be accessed from desktops and mobile devices with the same rich features. Also, users don’t need to install the PWA, as they can access it directly from the browser.

For example, one of our customers needed an app that helps cyclists with getting insurance. We created a lightweight and secure insurance progressive web app. It allows users to report an accident from their smartphones. Also, the app enables you to receive insurance policies and payments.

As we know the peculiar aspects of progressive web apps development services, we were also ready to help Impact Personal Training. The initial need of Impact was to make a fitness app for desktops and mobile devices. That was because the Impact trainers prefer desktops, and their clients opt for mobile devices to use the app.

So, we decided to develop the Impact fitness app as a PWA. Thanks to its cross-platform nature, the Impact PWA is well-adapted for both desktop and mobile devices.

Below you can watch a brief video that shows how this app works.

Features for clients

Exercises for personal fitness programs

The exercises you include in the app should be versatile and contain detailed descriptions. It is also helpful to have videos. Such videos also show comments on how to do the exercises correctly.

We included a convenient menu with exercises in the Impact fitness app. It shows the number of sets, reps, and tempo for exercises. Each exercise includes a detailed description and video of how to do them correctly.
