Why KuntoFit

Built for coaches who actually coach.

Assign the plan. Your clients train and log. Check-ins, messages and progress come straight back to you, so your time goes on coaching, not chasing people for updates.

Your morning

Know exactly who needs you, before you open a single chat

Quiet clients, missed workouts, unanswered messages and overdue check-ins are flagged for you.

Open KuntoFit and the people who need you are already at the top, with one-tap message, check-in and plan actions. A short email lands every morning too, so nobody slips through the cracks.

Programming

Build a program once. Run it for 50 clients.

Drag exercises into days, reorder in a second, save as a template.

Assign to one client or a whole group in three clicks, with a preview of who switches plans. Put clients into cohorts, edit the program and everyone gets the update. Need a knee-friendly swap for one person? Change it for them only.

Accountability

Check-ins and habits that keep clients showing up

Your questions, your schedule, their phone.

Ask one client or the whole roster for a check-in at once. Answers, photos and habit streaks land on each client's page, so you can spot a dip and act on it the same day.

Your clients

One simple app your clients will actually use

Today's workout, set logging, rest timer, habits, check-ins and chat.

No spreadsheets, PDFs or WhatsApp groups. Clients see exactly what to do today, log as they train, and send you voice notes, photos or form-check clips in the same thread.

Payments

Get paid in the app. Keep 100%.

Sell packages through your own Stripe on Studio and up. KuntoFit takes 0% commission.

Recurring or one-off packages, from the same place you coach. Stripe's normal processing fee is the only cost.

Trust

Your clients' data stays yours

Our team can't see your clients' training, messages or check-ins.

If you ever need help, you can let support look for 24 hours or 7 days, read-only, and every page they open shows in your activity log. Download all of your data whenever you like.

See all features

In the gym
