What does a fitness app include?
All parts connect through the same backend to keep workouts, bookings, members and revenue in sync.
Most fitness platforms have three parts: an app for members, tools for coaches, and an admin portal for your team. Your proposal lists the features for your app.
Member App
The app your members use every day to achieve their fitness goals, track their progress, and stay connected with classes and trainers.
Sign-up, profile and goals
Workout plans and video library
Class booking and check-in
Activity, nutrition and body tracking
Challenges, streaks and badges
Subscriptions and in-app payments
Push reminders and community
Connect your fitness app to the tools you already use
A fitness app is more useful when it uses the data and systems your members already have: health data, wearables, payments and your booking system.
Apple HealthKit and Health Connect
With the user's permission, your app reads and writes steps, workouts, heart rate and sleep data on iPhone (HealthKit) and Android (Health Connect).
Wearables
We connect Apple Watch and Wear OS apps, and devices such as Garmin and Fitbit through their official APIs.
Payments and subscriptions
Members pay through Stripe or Apple and Google in-app purchases, with recurring subscriptions, free trials and refunds.
Booking and gym management systems
We connect your app to your existing booking, membership or CRM system through its API, so members and staff use one set of data.
Video
Users stream workout videos on demand, and coaches run live or one-to-one video sessions.
Notifications and messaging
Reminders, streak alerts, class updates and real-time chat between members and coaches.
