Stop chasing, start coaching
Quiet clients, missed workouts and unanswered messages are flagged for you, every morning.
Software for online coaches and personal trainers
Programs, check-ins, habits and client chat in one place. Every morning KuntoFit shows you exactly who needs you, and your clients get one simple app to train, log and talk to you.
Week 0
The first week is showing up. Sleep, food, and the session you assigned.










16 weeks
Quiet clients, missed workouts and unanswered messages are flagged for you, every morning.
Drag-and-drop builder, templates, and assign to a whole group in three clicks.
Training, check-ins, habits, payments and chat in one app your clients actually open.
How it works
Drag exercises into days, or start from a template. Sets, reps, supersets and rest, done in minutes.
Send clients a code to join the app. Assign the program to one person or a whole group at once.
They train and log, check in and message you. You see who needs you first and act in a tap.





Why KuntoFit
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
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
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
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
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
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
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.
In the gym
Workouts, habits, and check-ins in one athlete app — so they don’t have to hunt around between tools.




On the floor
Made for the gym, not a dashboard demo.
Coach in your own voice. Clients send photos or short clips for you to review.
Macro targets, recipes and leaderboards in the same client app.
