Your clients, your method, your brand. All in one dashboard.
Tesonia brings clients, calendar, plans, diets, chat and progress together in one fast dashboard with your logo on it. Wide bands, small steps and nothing sold separately.
Import your Excel files with AI · Data hosted in the EU (Frankfurt)
The dashboard is in Spanish today; your language is on the way.

Block-based plans
Templates, supersets and your own videos.
Diets and recipes
Macros per meal, reusable recipes.
Chat with attachments
Plans, diets, photos and files inside the conversation.
App under your brand
Your logo and your colour on your clients' phones.
WHAT IT DOES
Fewer scattered tools, more time with your clients.
TRAINING
Programme once, assign to anyone you like.
Build plans by day and block, save them as templates and assign them to several clients in two clicks. Every exercise links to the YouTube video you choose: your technique, your voice.
- Exercise library with your own videos
- Supersets, RPE and notes per set
- Duplicate and tweak per client

NUTRITION
Diets with macros, no spreadsheet needed.
Create recipes once and combine them into diets by time slot. Calories and macros are worked out for you, and your client sees them on their phone.
- Recipes with ingredients and macros
- Diets by day and time slot
- Swap one meal without redoing the plan

TRACKING
Tracking with progress charts, not just numbers.
Weight, sleep, measurements and before-and-after photos, plus charts that cross any variable over time. Clients log their training (sets, weights and reps) from their app, and you see training volume by muscle group and load progression per exercise.
- Comparison charts: weight, sleep, measurements and volume
- Clients log their sets, weights and reps
- Volume by muscle group and load progression
- Before-and-after photos with a slider

COMMUNICATION
Talk to your clients without leaving the dashboard.
Direct chat with every client: attach the plan or the diet and they open it straight from the message, share photos and files, and get an alert when someone stops training.
- Chat with attachments: plans, diets, photos and files
- Your client opens the plan from the message
- Inactivity and renewal alerts

BUSINESS
Diary, appointments and fees under control.
A weekly calendar with video call links, configurable availability and subscription tracking so you know who renews this week.
- Appointments via Meet, Zoom, WhatsApp or in person
- Renewals and cancellations at a glance
- Monthly revenue and average ticket

YOUR CLIENTS' APP
Your brand on their phone, no app stores.
Your clients open Tesonia from the browser and add it to their home screen: today's workout, diet, weight, photos and chat with you, under your logo and colour.
- Home: today's session, next appointment and weight
- Plan: days, blocks and a video per exercise
- Chat: messages, photos and files with you

FREQUENTLY ASKED QUESTIONS
What people ask us before joining.
Another question? Write to us at hello@tesonia.com.
- Can I use my own videos?
- Yes. Every exercise in your library links to the YouTube or Google Drive video you choose. The linked content is yours and must respect copyright.
- What is my clients' app like?
- An installable app for their phone (iOS and Android) with your logo and your colour: the day's workouts with your videos, diet, weight, photos and a chat with you. If you want your own app published in the stores under your name, we can talk about it and quote it separately.
- What happens to my data and my clients' data?
- It sits on servers in the European Union (Frankfurt). You are the data controller for your clients' data and Tesonia is the data processor. Any client can ask for their data to be deleted, and you can do it from their profile.
- Is there a free trial?
- Yes: 7 days free on any plan. We ask for a card at signup and only charge when the trial ends; you can cancel before that from your profile at no cost.
- Can I migrate from another platform or from Excel?
- Yes, on your own. The panel has an "Import" tool: upload your Excel or CSV files as they are (clients, plans, exercises, recipes, diets and weights), the AI interprets them, you review and correct the result and confirm. If something is off, undo it with one click. Coming from another platform? Export to Excel there and do the same.
