Fitness app development teams that keep users coming back, not just signing up.
Hire dedicated senior engineers from a staffing partner founded by a four-time founder. We place engineers in the Philippines who build workout, wearable, nutrition, and subscription apps that hold onto users past the first week. Pre-vetted, full-time, and ready in 7 days.

Not a dev shop building it for you. Your fitness app team, building with you.
Most fitness app development companies quote you a six- or seven-figure fixed-bid project, build it behind a vendor wall, and hand it back. We staff dedicated senior engineers into your team. You own them, manage them, and keep them.
The turnkey vendor model
The big custom-software shops
- Fixed-bid project, scoped up front, priced in the hundreds of thousands
- Engineers walled off behind an account manager
- 30–40% overhead for layers you never meet
- Hand-off at the end, and the knowledge walks out the door
The Full Scale staff-augmentation model
Dedicated engineers, embedded in your team
- $35/hr fully loaded, scale up or down as the roadmap changes
- Engineers in your standups, Slack, repo, and roadmap
- No vendor wall and no PM tax, you manage them directly
- 93%+ retention means the engineers, and the knowledge, stay
Co-founded VinSolutions, the #1 CRM in the auto industry ($150M+ exit), and founded Stackify
Built by a founder who has shipped and sold real software
Full Scale was founded by Matt Watson, a four-time founder and CTO with 20+ years in software engineering. He co-founded VinSolutions, the #1 CRM platform in the auto industry, acquired for around $150 million, and founded Stackify, a developer-tools company he later sold. He also wrote Product Driven, the engineering-leadership method every Full Scale engineer is trained on.
Full Scale exists because Matt kept hitting the same wall as an operator: good products stall when you can't hire and keep good engineers. That is the problem we solve, and it is why we vet for the senior, product-minded engineers most staffing shops never find.
Engineers experienced across the fitness app stack
We don't sell you a pre-built product. We staff engineers who have shipped consumer health and fitness software before and know what it takes to keep users engaged past the first week.
Workout & training apps
Guided workouts, training plans, video coaching, rep and set tracking, and progress logging that users actually return to.
Wearable & device integration
HealthKit and Google Fit integrations, smartwatch apps, heart-rate and sleep sync, and the messy edge cases of real device data.
Nutrition & wellness
Meal and calorie tracking, macro logging, hydration and habit tracking, mindfulness, and wellness coaching features.
Social & community features
Challenges, leaderboards, friend feeds, group classes, and the social loops that turn a workout app into a habit.
Subscriptions & monetization
In-app purchases, subscription tiers, free trials, paywalls, and billing built to App Store and Play policies.
Fitness data & analytics
Activity dashboards, progress charts, cohort and retention analytics, and machine-learning pipelines on workout and biometric data.
Engineers who treat health data like the sensitive data it is
Fitness apps collect biometric and health data, and the app stores enforce real rules about how you handle it. Our engineers build privacy and consent in from the start, not as a checkbox before launch.

Why most fitness apps lose users, and how to not be one of them
The mistake isn't going offshore. It's hiring the cheapest developer you can find and hoping retention sorts itself out. I call that cheapshoring, and in consumer fitness it's how you end up with an app that downloads well and gets deleted in a week.
A fitness app lives or dies on whether people come back. That takes engineers who care about the product, not just the ticket, who notice that a slow sync or a clunky onboarding is why users churn. That's a hiring bar, not a rate, which is the whole reason we accept under 3% of applicants and train every engineer on the Product Driven method.

Fitness App Development Services, answered
- Do your engineers have fitness and consumer app experience?
- Yes. We staff engineers who have shipped consumer health, fitness, and wellness apps, including wearable integrations and subscription billing, and who care about retention, not just the build.
- Can you integrate with HealthKit, Google Fit, and wearables?
- Yes. Our mobile engineers have built HealthKit and Google Fit integrations and smartwatch apps, and they know the device-data edge cases that break most fitness apps.
- Is this a fixed-bid project or a dedicated team?
- A dedicated team. We are a staff augmentation partner, so you get engineers embedded in your team at $35/hr, not a turnkey project quote.
- How fast can a fitness app team start?
- Seven days from the first call to engineers in your standups, drawing from a pre-vetted bench.
- Who owns the code and the IP?
- You do, from day one. Our engineers work in your repositories under your process.
