Social features and freemium models that turn users into a paying community.
Runners High case
Sleep, meditation & wellness
Content apps with retention designed in: 90,000 new users a month on one we built.
Sleep meditation app caseFeatures fitness apps need
A fitness app keeps users when it fits into how they train: it tracks progress, connects to the devices they wear and gives feedback they can act on. These are the building blocks we have shipped in sports and wellness products.
Subscriptions & freemium
Paywalls and free tiers that convert. Runners High grows a paying community on a freemium model.
In-app chat
Coaches and athletes in one thread. In OnForm, coaches review an athlete’s video and reply without leaving the app.
Video analysis
Slow motion, markup and side-by-side comparison of training videos, built for OnForm’s coaches across 150+ sports.
Wearable integrations
Connect the devices your users wear. For the Reebok Fitness App we integrated the Reebok Smart Ring, so heart rate, recovery and sleep data appear live in the app.
Health data sync
Steps, workouts and sleep from Apple HealthKit and Google Health Connect in one summary, as in the Reebok Fitness App.
Challenges & leaderboards
Challenges, leaderboards and real-life prizes that keep users training, as in the Reebok Fitness App.
Music streaming
Spotify and YouTube Music playing inside workouts, so users don’t switch apps mid-session.
AI technique feedback
Computer vision on the phone camera that measures technique and gives feedback in real time, as in the Tekkers AI football coach.

How much does it cost to build a fitness app?
Most fitness products start with a mobile MVP. See typical ranges on our pricing page, or upload your brief for a free AI estimate.
How long does it take to build a fitness app MVP?
Usually 4–6 weeks of development, after a 1–2 week discovery phase and 2–3 weeks of product design, the same timings as on our pricing page.
Can you integrate wearables and music services?
Yes. In the Reebok Fitness App we integrated the Reebok Smart Ring, Apple HealthKit, Google Health Connect, Spotify and YouTube Music.
Do you build AI coaching features?
Yes. For Tekkers we built an AI football coach that uses the phone camera and computer vision to give players feedback on their technique.
Do fitness apps need HIPAA compliance?
Usually not. HIPAA applies when a healthcare provider, an insurer or their business associate handles protected health information. A consumer fitness app outside that relationship is typically not covered, but privacy laws such as GDPR still apply. We confirm what applies to your product during discovery.
