Frequently Asked Questions
How much does it cost to build a fitness app like Fitbit or Cult.fit?
It depends on what you include — video classes, wearable sync, subscriptions, AI coaching. A tracking-focused MVP starts in the low five figures; a full platform with live classes and AI costs more. Send your requirements and we'll put together a free, detailed quote.
How long does it take to develop a fitness app?
An MVP usually takes 10-14 weeks. A complete app with live classes, wearable integration, subscriptions and AI coaching can stretch to 4-6 months. We build in agile sprints with regular demos throughout.
Can the app integrate with wearables and health platforms?
Yes. We connect Apple Health, Google Fit and popular wearables to sync steps, heart rate, sleep and workouts — so users get one unified view of their progress.
Can you add an AI fitness coach?
Yes. Our AI coaches tune workout and nutrition plans to each user's goals and progress, handle meal recognition, and use OpenAI-powered chat to answer questions and keep people motivated.
What clients say
“We have been working on this project for about 11 months. Navratan and the team at GTS did a great job getting us to a good point and completing the MVP. The project has a very large amount of moving parts that changed continually. I appreciate their patience and persistence in delivering a good product.”
