Kluva is all-in-one software for personal trainers and small training studios in Spain, in Spanish. Trainers run their business from a web dashboard: workout routines and multi-week programs, meal plans and recipes, progress tracking (weight, measurements, photos and check-in forms), chat with each client, and an agenda with bookings, classes with capacity limits and session packs. Payments go through the trainer's own Stripe account with 0% commission from Kluva: subscriptions, packs and one-off payments by card or SEPA direct debit, with VAT invoices issued automatically. Clients follow their plan, log their sessions and book from the Kluva app on their phone. Teams get roles and permissions, and every trainer gets a public page to attract new clients. Plans from €18.15/month (VAT included), with a 30-day free trial and no card required.
