The project

Two users, opposite needs

A coach needs a workspace for building plans, managing clients and running the business. A client needs today’s workout on their phone and nothing else. One product had to serve both, without either side feeling like an afterthought.

Two apps, one system

Coaches work in a web app. Clients use a phone app. Both run on the same data, so when a coach changes a plan, the client sees the change straight away.

Keeping score

Showing up is the hard part of training, so the app keeps score. Workouts earn points, clients compete in a weekly league, and milestones earn badges.

For gyms, and for each coach

A gym can bring several coaches under one account, with shared templates and invites. Each coach also gets their own small website, so new clients see their coach’s brand first, not the app’s.

The coach’s desk

The whole business, in one browser tab

The web app a coach runs their day from: clients, programs, calls and payments.

Client management
Every client, plan, check-in and history on one roster. Sub-coaches see only the clients assigned to them.
Program builder
Workout and nutrition programs built once, saved as templates, and adjusted per client without touching the template.
Check-ins and progress
Weekly check-ins with body metrics, wellbeing scores and progress photos, charted over time.
Live video calls
Coaching calls run inside the app, next to the client’s plan. No meeting link to send.
Chat and community
Real-time messages with every client, and a community feed for the whole roster.
Packages and payments
Coaches sell packages in the app and get paid through Stripe, straight into their own account.
