The desk

Everything you run a practice with, in one place.

Program

Sessions, progressions, on-demand libraries. Hand the week over in one tap.

Fuel

Targets, meal ideas, a food log in plain English. No screenshot dump at 10pm.

Check-ins

Sleep, weight, photos, how the week felt. One thread per client.

Pay

Packages they can buy. Stripe takes the card. You keep the relationship.

From the floor

Coaches stay. Clients come back.

“I stopped living in three apps and a notes file. The floor still gets my voice. The software keeps the rest.”

Nora Ellison

Strength & conditioning, Portland

“I finally have a session waiting when I walk in. She sees the food log. I don’t explain the week from scratch.”

James Okoye

Trains with Nora, two evenings a week

“Check-ins land with sleep, weight, and how it actually felt. Not a voice note lost in WhatsApp.”

Maya Chen

Online coach, 40 clients
