Client management for gyms, PTs, and nutritionists
Theron replaces the spreadsheet-and-WhatsApp roster with a real client management dashboard: invite clients by email, see who accepted, and manage your full list — gym members, PT clients, or nutrition clients — from one place.
Manage your clients — from €35.99/moWhy spreadsheet-based client management breaks down
A spreadsheet works for five clients. It stops working at twenty, once you're tracking who's active, who's assigned which plan, and who needs a follow-up. A real client management dashboard scales with your roster instead of becoming its own part-time job.
How client management works
Invite by email
Send an invite — no manual account setup on your end.
Track acceptance status
See exactly who has accepted and who's still pending.
View your full roster
Every client — gym member, PT client, or nutrition client — in one list.
Drill into any client
Open a client's detail view for their full history and assigned plans.
No spreadsheets
One dashboard instead of a spreadsheet plus a separate messaging thread per client.
Scales with your roster
Works the same whether you have 10 clients or 200.
Works for any client type
Gym members, PT clients, and nutrition clients managed in the same system.
Connects to everything else
Feeds directly into plan assignment, compliance tracking, and session scheduling.
Who uses client management
Gym owners
Managing a full member roster without a legacy gym ERP system.
Personal trainers
Running an online or in-person PT business with more clients than a spreadsheet can handle.
