Fitness & Workout App Development
Last updated: February 2026
A fitness app with structured workout plans, a video exercise library, progress tracking, wearable and HealthKit integration, nutrition logging, and subscriptions.
Technologies Used:
Overview
We build complete fitness and workout apps that combine guided workout plans, a searchable video exercise library, progress and body-metric tracking, nutrition and calorie logging, and wearable integration with Apple HealthKit and Google Fit. A subscription layer unlocks premium plans and coaching, and a coach or admin panel lets trainers manage programs and members. It is built for fitness coaches, studios, and wellness startups that want a branded app to deliver programs, retain members, and earn recurring revenue rather than rely on generic platforms.

Frequently Asked Questions
What drives the cost of a fitness app?
The main cost drivers are video content delivery, wearable and HealthKit or Google Fit integration, the nutrition database, personalized or AI-driven plan generation, and the subscription layer. A workout-and-tracking MVP is much lighter than a platform with live classes, coaching, and a community feed. We scope it to your goals and give you a fixed quote.
Can it sync with Apple Watch, Fitbit, and other wearables?
Yes. We integrate Apple HealthKit and Google Fit, which pull data from Apple Watch, Fitbit, and most major wearables for steps, heart rate, and calories. This keeps the app as the single source of truth for a member's activity without us building a separate integration per device.
Can you build the subscription and in-app purchase system?
Yes. We implement subscription tiers and in-app purchases through Stripe and the App Store and Google Play billing systems, with receipt validation and entitlement logic so premium plans and coaching unlock reliably and stay store-compliant.
Does it run on both iOS and Android?
Yes. We build with React Native so the app ships to both iOS and Android from one codebase, while still using the native HealthKit and Google Fit layers on each platform for accurate health data.
Do you handle app store submission?
Yes. We manage the full submission to the App Store and Google Play, including health-data privacy disclosures, subscription configuration, and listing assets, and we push the builds through review for you.
