Fitness products people stick with.
Coaching apps, gym platforms and connected fitness products — with wearable integration as a first-class citizen and the engagement design that keeps people coming back.
A fitness app wins on week three, not day one.
Anyone can ship a workout tracker; keeping people in it past the initial burst is the real engineering and design problem. We build wearable integration as a foundation so HealthKit and Google Fit data flows in instantly, keep metrics synced in real time across watch, phone and web, and design the habit loops, challenges and coaching that turn a download into a daily routine. Retention is the number we build toward.
The sector, honestly.
Fitness software has one brutal metric: retention. The market is full of beautifully designed apps that users abandon in week three. Winning means meeting people where their data already lives — their watch, their ring, their wearable — and giving them a reason to return.
We build connected-fitness products with HealthKit and Google Fit integration as a foundation, real-time sync across devices, and the coaching, habit and community design that turns a download into a daily habit.
Behind the app, we build the gym, studio and trainer operations — membership, booking, payments — so the business side runs as smoothly as the workout on screen.

The hard parts, handled.
The principles we build by in this sector — and what each one means once the system is live.
Retention is the metric
We design for the return visit, not the install — habit loops, streaks and timing tuned to keep people coming back.
Meet the data where it lives
HealthKit and Google Fit are first-class, so users’ existing watch and wearable data flows in from day one.
Real-time across devices
Workouts, metrics and progress stay in sync across phone, watch and web without the user thinking about it.
Coaching that feels personal
Programmes and nudges adapt to the individual, because generic plans are the fastest route to churn.
From startups to scale.
