Build a fitness app for personal trainers—clients see assigned workouts with video demos, log sets and reps, track daily macros with a meal planner, upload weekly progress photos.

Why 2,500+ Fitness Pros Use This

Workout Library with Video Demos

Pre-loaded exercise database with video form guides, muscle groups, equipment tags. Add your own custom movements. Trainers assign workouts, clients log reps and weights—all synced in real time.

Meal Planning with Macros

Build meal plans with auto-calculated calories, protein, carbs, fats. Swap ingredients, scale portions, generate shopping lists. 74% of users who track nutrition alongside workouts see better results within 90 days.

Progress Photos and Measurements

Clients upload weekly check-ins with photos, weight, body measurements. Side-by-side comparison views show visual progress over time. One trainer told us this feature alone reduces client dropout by 35%.

Client Communication Hub

In-app messaging, workout feedback, form check requests. Trainers respond with video clips or voice notes. Keeps everything organized—no more digging through text threads.

Subscription and Payment Management

Charge for training plans, monthly coaching, or one-time programs. Stripe integration handles recurring billing, failed payments, refunds. You focus on training, not chasing invoices.

White-Label Branding

Your logo, your colors, your domain. Clients see your brand, not ours. Paid plans let you remove all platform branding and publish under your own name in app stores.

Lessons from Fitness Apps That Stick

1. Make Logging Workouts Stupid Easy

The faster someone can log a set, the more likely they'll use the app daily. Quick-add buttons, templates for recurring workouts, copy last week's session—every second saved matters.

2. Visual Progress Beats Numbers Alone

Graph weight over time, show before/after photo sliders, highlight PRs. People stay motivated when they can see change, not just read spreadsheets.

3. Push Notifications at the Right Time

Remind clients 1 hour before scheduled workouts. Celebrate streaks. Ask for check-ins on Sundays. Spamming daily motivational quotes? That gets ignored fast.

4. Offer Pre-Built Programs for Quick Wins

Not every client wants fully custom plans. Include ready-made 8-week programs (fat loss, muscle gain, beginner strength). Trainers can tweak them in 60 seconds instead of building from scratch.

5. Integrate Wearables If Your Clients Use Them

Sync with Apple Health, Google Fit, or Fitbit. Auto-import steps, sleep, heart rate. Makes the app feel like a complete fitness hub, not another thing to manually update.

6. Include Rest Day Content

Mobility routines, stretching videos, recovery tips. The best apps keep users engaged even when they're not lifting weights.
