The average fitness app is deleted within weeks. We build habit-forming experiences that sync with wearables, personalize every session, and keep members subscribed past January.

HabitsThatStick

Motivation spikes and fades, so retention is the whole game in fitness. We build apps that turn workouts into streaks, personalize plans to real progress, and pull in the wearable data your users already generate. Whether it's a studio membership app or a global fitness platform, we design for the long haul, not the download spike.

ProblemsWeSolve

The friction points that quietly cap growth in fitness, and how we engineer them away.

Brutal post-signup churn

Motivation fades fast and most users delete a fitness app within the first two weeks.

Fragmented health data

Users expect their wearables, HealthKit, and workouts to sync, and a disconnected app feels broken.

Generic one-size plans

Static programs that ignore real progress bore beginners and under-challenge advanced athletes.

Clunky class booking

Studios lose members to waitlist chaos and no-shows when scheduling and payments feel painful.

Weak subscription economics

Without strong retention and upsell loops, subscriber acquisition cost never pays back.

WhatWeBuild

The products fitness teams come to us for, from first MVP to a platform at scale.

Workout and training app

Guided, adaptive programs with video coaching that scale from first-timers to competitors.

Wearable-connected tracker

Real-time sync with Apple Watch, Garmin, and Whoop so every stat lives in one place.

Studio and class booking app

Schedules, waitlists, memberships, and payments that keep classes full and staff sane.

Challenges and gamification

Streaks, leaderboards, and social challenges that turn effort into a habit people defend.

Nutrition and wellness app

Meal logging, macro tracking, and recovery guidance that round out the whole health picture.

On-demand content platform

Live and recorded classes with subscription tiers and offline download for training anywhere.

WearablesandHealthKit

In fitness, credibility comes from the data being right and private. We integrate deeply with Apple HealthKit, Google Fit, and the major wearables so heart rate, sleep, and activity flow in accurately and in real time. Because this is health data, we build to HIPAA-grade privacy and platform health-data policies from the start.

FEATURED BUILD

PulseFit, beating the February cliff

A boutique studio chain had a strong brand but an app that hemorrhaged members after the New Year rush. We rebuilt it around adaptive plans, wearable sync, and social challenges tied to their class booking and billing. Retention held deep into the year instead of collapsing in February.

“Our app used to be a New Year's resolution that got deleted by spring. Now it's the reason members renew, and the wearable sync alone changed how our coaches program.”
