Fitness App Development
Plan, Architecture, Costs
In mobile app development and healthcare IT since 2005, ScienceSoft builds world-class wellness apps with resilient architecture and engaging UX.
Fitness Apps: The Essence
The key goal of fitness app development is to meet the ever-growing demand for easy-to-use, accessible apps that help people maintain physical and mental wellness. Varying from fitness tracking, workout guidance, and nutrition planning to mindfulness solutions, fitness apps make a big difference in their users' everyday lives.
- Key steps: business analysis, requirements engineering and planning, UX/UI design, development and testing, release and maintenance, continuous evolution.
- Team: project manager, business analyst, solution architect, developers, QA specialists, DevOps engineer, regulatory compliance expert (optional).
- Costs: from $50,000 for an MVP and up to $600,000 for a full-featured product, depending on the chosen feature set and development method (native, cross-platform).
With a passionate team of experienced mobile developers and healthcare IT consultants, ScienceSoft provides end-to-end development of fitness apps. We offer business analysis, design, coding, testing, support, and evolution of fitness apps of any complexity.
The Fitness App Market
The global fitness app market was estimated at $1.1 billion in 2021 and is expected to grow sixfold within the following decade, reaching a valuation of $8.1 billion by 2032. The surge in demand for fitness apps is associated with the COVID-19 pandemic that raised public awareness of healthy lifestyle and affected brick-and-mortar fitness businesses.
Fitness tracking
- Manual and automated activity logging: e.g., steps taken, heart rate, calories burned.
- GPS tracking (mapping out the route, calculating the pace and the distance traveled).
- Nutrition logging and calculating the calorie intake by entering the meals manually, choosing foods from the in-app list, or scanning food barcodes.
- Sleep tracking.
- Period and pregnancy tracking.
- Mood logging and journaling.
- Lifestyle tracking (e.g., physical and mental rest, habits, sexual activity, and more).
Personalized user experience
- User profile personalization (logging in age, height, weight, preferred activities to create a tailored fitness plan).
- Goal setting and progress tracking with daily/weekly/monthly reports.
- Custom workout and nutrition plans tailored to a user's fitness level, preferences, and goals (e.g., weight loss/gain, muscle building, regular physical activity).
- Push notifications and reminders to log in your daily activities and compensate for the missed ones.
Training and education
- Pre-recorded, animated, or illustrated workout sessions for an activity of choice (e.g., yoga, workout using gym equipment, stretching).
- Meditation, breathing, and other mental health exercises in a video, audio, or written format.
- Real-time one-on-one video sessions with trainers, meditation teachers, or nutritionists.
- Articles, FAQ guides on a healthy lifestyle.
- AI chatbot providing recommendations based on users' goals, logged-in activities, etc.
- Information on nearby healthcare and fitness organizations.
Community
- Synchronization with social media (e.g., for sharing fitness achievements with friends, logging in via social media accounts).
- Gamification: in-app competitions with daily/weekly/monthly challenges, progress levels, and unlockable rewards like profile badges, discounts, free access to premium content, etc.
- Information about and notifications of a user's friends' recent activity and fitness achievements, peer support.
Security
- Multi-factor authentication (e.g., biometric login, PINs, SMS codes).
- Secure cloud storage, data encryption.
- HIPAA, GDPR, PCI DSS compliance.
Billing and payment
- Secure payment gateways to accept in-app payments (for premium functionality, individual training sessions, etc.) through different channels (e.g., a card, Google Pay, Apple Pay).
- User invoicing and automated sales tax handling.
- Handling payment failures.
Sample Fitness App Architecture
Below, ScienceSoft's mobile app experts outline the key building blocks of a microservices-based fitness app architecture and describe its key components.
- Presentation layer is the app’s UI, the central point of user interaction. For fitness apps that accommodate different user roles (e.g., trainee, trainer, admin), different UIs with corresponding user access rights are created.
- Routing layer serves as an intermediary between the front end and the back end, ensuring a smooth and secure exchange of data.
- Container ecosystem is the app's back end that consists of several microservices and their respective databases, one for each primary module of the app.
LEARN MORE ABOUT EACH MICROSERVICE
Microservices in detail
- User's profile microservice collects and stores user data. Communicating with the payment microservice, it verifies a user's payment status (if applicable) and enables access to premium content or paid app features.
- Nutrition microservice helps log daily food and water intake, calculating the nutritional value of meals by choosing foods from the nutrition database or scanning a food item's barcode, etc.
- Training microservice contains the workout sessions and mental health exercises provided by the app. It allows users to choose their preferred activities and workout difficulty level, log their training sessions, track fitness progress, and more.
- Education microservice is designed to encourage the users' interest in fitness-related topics and provide comprehensive information about a healthy lifestyle in an easy-to-digest format.
- Goals microservice helps users keep up with their fitness goals, reminds them about missed activities, and encourages new accomplishments with push notifications.
- Recommendations microservice collects comprehensive data about a user's goals and activities from all the microservices to generate personalized recommendations and a tailored fitness program. Relevant tips might be provided with an AI chatbot that sends notifications to the user.
HIDE
Independent modules are easy to deploy, scale, and modify, making microservices a perfect option for complex fitness apps that are likely to evolve with new features in the future.
- Setting business goals to be achieved with the future app (e.g., filling a market niche, promoting fitness products or services, etc.), define the expected goals to conceptualize the fitness product.
- Examining the target market segment and the competitors' offerings.
- Identifying the target audience and creating empathy maps to pinpoint potential users' pains.
- Identifying the app's compliance needs (e.g., HIPAA, GDPR).
- Developing a business case for the app, including the development cost and ROI estimations.
In most cases, fitness apps fall under the FDA requirements for low-risk devices as they are designed for general wellness use only, have no relation to diagnosing, curing, or preventing diseases and pose no risk to users’ safety. If your app fits this description, it will not require FDA submission.
- Creating a high-level vision of the fitness app by outlining:
- The app's purpose (e.g., an exercise guide, a fitness tracker, a nutrition advisor) and its competitive edge.
- The core feature set and integrations (if applicable).
- Functional and non-functional requirements, including security and compliance requirements.
- App monetization model (a paid app, in-app purchases, ads, etc.).
- Choosing the mobile platform (iOS, Android, both).
- Designing the optimal mobile app architecture.
- Selecting the best-suited back end technology stack.
- Creating a detailed software requirements specification (SRS).

We use Amazon DynamoDB as a NoSQL database service for solutions that require low latency, high scalability and always available data.
Azure SQL Database is great for handling large volumes of data and varying database traffic: it easily scales up and down without any downtime or disruption to the applications. It also offers automatic backups and point-in-time recoveries to protect databases from accidental corruption or deletion.
We leverage Azure Cosmos DB to implement a multi-model, globally distributed, elastic NoSQL database on the cloud. Our team used Cosmos DB in a connected car solution for one of the world’s technology leaders.
We use Google Cloud Datastore to set up a highly scalable and cost-effective solution for storing and managing NoSQL data structures. This database can be easily integrated with other Google Cloud services (BigQuery, Kubernetes, and many more).
