Competitors charge $180–220/mo once you add nutrition, payments, video and automation add-ons. Here every feature ships in the plan — and client payments cost 0–1%, EU-first, while many platforms sell payments as a separate paid add-on.

Get startedFrequently asked questions
Χρειάζομαι κάρτα για να δοκιμάσω;
Όχι. Κάθε νέος λογαριασμός ξεκινά με δοκιμή 30 ημερών σε όλες τις λειτουργίες, χωρίς κάρτα. Όταν τελειώσει, κρατάς όλα τα δεδομένα σου και συνεχίζεις στο δωρεάν πλάνο.
Πρέπει να πληρώσουν και οι πελάτες μου;
Όχι. Οι πελάτες μπαίνουν δωρεάν με πρόσκληση από τον προπονητή τους και δεν χρειάζονται δικό τους πλάνο.
Τι κοστίζει να δέχομαι πληρωμές από πελάτες;
Η προμήθεια της πλατφόρμας είναι 1% στο πλάνο Solo, 0,5% στο Trainer και 0% στο Gym. Στο δωρεάν πλάνο οι πληρωμές δεν περιλαμβάνονται. Οι χρεώσεις του παρόχου πληρωμών είναι ξεχωριστές.
Υπάρχει έκπτωση για ετήσια πληρωμή;
Ναι — η ετήσια πληρωμή αντιστοιχεί σε δέκα μήνες, δηλαδή δύο μήνες δώρο, σε κάθε πληρωμένο πλάνο.
Μπορώ να ακυρώσω όποτε θέλω;
Ναι, οποιαδήποτε στιγμή. Δεν υπάρχει δέσμευση και δεν χάνεις δεδομένα: ο λογαριασμός σου συνεχίζει στο δωρεάν πλάνο.
Χρειάζεται να κατεβάσω εφαρμογή;
Όχι. Δουλεύει σε οποιονδήποτε browser και εγκαθίσταται στην αρχική οθόνη σαν κανονική εφαρμογή, χωρίς app store. Λειτουργεί και εκτός σύνδεσης.
Είναι στα ελληνικά;
Ναι, πλήρως — και στα ελληνικά και στα αγγλικά, με έναν διακόπτη στην κορυφή κάθε σελίδας.
Τι κάνει ακριβώς το AI;
Ετοιμάζει προσχέδια προγραμμάτων και πλάνων διατροφής από τα δεδομένα του πελάτη. Εσύ ελέγχεις, διορθώνεις και εγκρίνεις πριν φτάσουν σε αυτόν — οι θερμίδες και τα μακροθρεπτικά υπολογίζονται ντετερμινιστικά, όχι από το μοντέλο.
Μπορώ να το χρησιμοποιήσω μόνο για τον εαυτό μου;
Ναι. Το δωρεάν πλάνο είναι ακριβώς αυτό: προπονείσαι μόνος σου, χωρίς πελάτες και χωρίς AI. Δεν χρειάζεσαι πρόσκληση από προπονητή.
Δουλεύω με ομάδα προπονητών — τι χρειάζομαι;
Το πλάνο Gym: περιλαμβάνει 3 θέσεις προπονητών και 250 κοινόχρηστους πελάτες, με επιπλέον θέσεις κατόπιν χρέωσης.
