You stay in control of every session, client and payment.
Bookings, payments and no-shows: all handled automatically.
Clients book themselves from your live availability and pay on time. Nutrition, training plans and progress live in one app, instead of three.

01The client goes quiet, does not show, and you just lost €20 and an hour you could have coached someone else.
02It is 9:47pm and another message lights up your phone: „hey, when do we train?“ Again.
03Your clients have a nutrition app, a tracking app, and your WhatsApp. Guess which one they open.
04A booking tool fills your calendar. It does not get your no-show money back. Different job.
05Which of the twenty in your class did not pay this week? You carry it in your head, and one of them is bleeding you.
One app replaces the nutrition app, the tracking app and WhatsApp. This is what is inside.
Set calories, days and style. AI drafts the first version in your nutrition approach in seconds, factoring in the client's allergies and goals. You fine-tune it and send, in the client's language.

Contact, goal, health, session history, payments and remaining credits. Reviews, health questionnaire and client progress in one profile.

Working hours, availability windows and group capacity. Clients book themselves, you just confirm. Recurring slots and personal blocks too.

Prepaid sessions, a revenue overview and who has not paid. The system enforces your cancellation and no-show rules for you.

A public consultation link turns followers into booked consultations right inside the app.

Clients book themselves. Your WhatsApp has finally gone quiet. You open the app in the morning, see four sessions and zero unpaid. Monday no-show credited you instead of stealing your hour. You did not chase anything. You just coach.

Clients book themselves from your availability.

Meal plans, workouts and payments in one place.
Not just another booking calendar.
We compared the five best-known coaching tools (Calendari, Trainerize, TrueCoach, PT Distinction, Everfit). Each covers only a slice. Treneris runs your whole business in one place.

Sindy Kanisová
Certified personal trainer“My clients used to need three apps: one for their meal plan, one for weigh-ins, and WhatsApp to book. Now they have one. They book themselves, so I am not replying to messages all day. I got my time back.”
Payments, cancellation rules, meal plans, progress, clients. Set the rules once and the app enforces them for you. Built with top coaches: what you ask for ships in weeks.

No. A booking tool sells slots in a calendar. Treneris runs the business: payments, no-show rules, meal plans, progress, clients. Not one of five competitors gets your no-show money back.
