The cost of building a custom fitness app depends on what you want it to do and how advanced the experience is.

A simple workout app with basic plans and tracking is usually on the lower side. Once you add things like video coaching, subscriptions, progress tracking, or wearable integration, the cost increases. If you go further with AI-based training or live sessions, it becomes a more serious investment.

On average, you can expect:

• Basic app: around $20,000 to $40,000
• Mid-level app: around $40,000 to $80,000
• Advanced app: $80,000 to $150,000+

The main cost drivers are features, design quality, backend setup, and integrations. Even small details like video streaming or real-time tracking can increase development time.

Also, most apps need ongoing updates after launch, which is something many people forget when planning budget.
