FAQ

Questions fitness founders ask us.

Didn't find yours? Ask us directly — we reply within 24 hours.

How much does it cost to build a fitness app?

It depends on features, platforms, video and wearable integrations. A focused MVP typically ranges from $10,000 to $30,000; we give you a detailed estimate after a free discovery call.

How long does development take?

Our fitness products reached full release in 4–9 months — Commit in 4, Family F.C. in 5, BURN in 8, eargym in 9. An MVP can be ready much sooner.

What features should a fitness app have?

Video and audio workouts, a training calendar, activity tracking, wearable sync, progress stats, social features and subscriptions. We help you pick the few that matter for launch.

Do you integrate with wearables and health platforms?

Yes — Apple HealthKit, Google Health Connect, Apple Watch, Wear OS, Garmin, Strava and Bluetooth devices like the Luminette light-therapy glasses.

Can you add AI to our existing fitness app?

Yes. We start with the use case closest to retention — usually personalised plans or an AI coach — build a proof of concept on your data, then roll it out with cost and safety controls.

Does Perpetio have fitness app experience?

Yes — from BURN, the workout app of a creator with 350M+ views, to live personal training, kids football coaching, light therapy, corporate wellness and goal-accountability apps.
