The Coaching App That Works Like an ERP — Without the Bloat
What a coaching app should actually do: clients, plans, progress, sessions, and a client app in one place. Here is the coach ERP Theron gives trainers and nutritionists.
Ask ten coaches what a "coaching app" is and you get ten answers: a booking calendar, a macro tracker, a workout logger, a chat thread, a PDF plan sent over email. Each solves a slice. None of them run the business. What a coach actually needs is closer to an ERP — one system of record for the whole practice — just without the enterprise weight that word usually drags in.
This is what Theron is built to be: a coach ERP that runs on the two things a coaching business is actually made of — clients and the plans they follow — with everything else arranged around them.
What a coaching app has to cover
A coaching business, stripped to its parts, is a short and stubborn list. A real coaching app has to hold all of it in one place, or you end up stitching apps together and losing the thread between them:
- The client — who they are, their goals, their history
- The plan — nutrition, training, or both, built and assigned
- Progress — are they adhering, are they improving
- Sessions — when you meet, and whether they showed
- The client's side — how they see their plan and log their days
- The business — your numbers, your data, exportable and yours
Miss any one and it leaks into a spreadsheet, a notes app, or your memory. The point of a coach ERP is that none of it leaks.
What Theron provides for coaches
Here's the whole surface, mapped to that list — this is the "what we provide" answer, concretely enough to judge the fit yourself.
Client management in one dashboard. Invite clients by email, see who's accepted, and manage every one from a single gym and coaching dashboard. No contacts app, no spreadsheet of names — the client list is the spine of the system, and everything hangs off it.
Reusable meal & workout plans. Build a plan once, then assign it to any client it fits. This is the feature that pays for the software: most coaches rebuild the same plan by hand for every client, and that time never comes back. Nutrition plans, training plans, or both together — one builder.
Progress & adherence tracking. Compliance, weight trends, and goal progress per client. The job isn't the dashboard looking busy — it's catching the client who's drifted while it's still a conversation and not a cancellation. Retention is the number a coach ERP has to move.
Session scheduling that knows the client. A week calendar of recurring training, assessment, and consultation sessions with attendance status — session scheduling tied to each client's plan and progress, not floating in a separate booking app.
A client app included. Every client gets the Theron iOS and Android app — their plan and their progress in their pocket, which is where adherence between sessions actually happens. Clients are not charged for it.
Your data, exportable. Clients, plans, and revenue to Excel anytime. A coach ERP you can't leave isn't a system, it's a hostage situation — so export is a first-class feature, not a support ticket.
Built for coaches, not for chains
The reason most "all-in-one" platforms feel heavy is that they're facility ERPs — built for a multi-location chain and sold down to coaches who use a fraction of them. Theron is scoped the other way: it does the coaching corner completely and deliberately leaves out what a solo coach or small studio doesn't run.
No POS. No subscription-billing engine. No door access control. No lead-scoring pipeline. If you need those, you run a facility and want a facility ERP — read gym ERP vs modern software for that call. If you run a book of clients, those modules are just menus you never open.
That focus is why it's same-day, not an onboarding project — and why pricing is published: from €35.99/month for up to 10 client seats, then per seat as you grow, added or removed anytime and billed pro-rated. Seven-day free trial, no credit card.
Who it fits
Theron is the right coaching app if you are a:
- Personal trainer running clients on training plans — personal trainer software with scheduling and progress built in.
- Nutrition coach or dietitian running clients on meal plans — nutrition coaching software for macros, adherence, and plan reuse.
- Small gym or studio where member results are the product, not facility access — a lightweight gym management dashboard without the ERP bloat.
If two or more of POS, membership billing, and access control are load-bearing for you, it isn't the fit — and a lighter tool would be a gap you'd fill with spreadsheets. Be honest about which business you run.
Conclusion
A coaching app shouldn't be a single feature pretending to be a system, and it shouldn't be a facility ERP wearing a coach costume. It should be the handful of things a coaching business is actually made of — clients, plans, progress, sessions, a client app, your data — held in one place and built properly. That's the coach ERP Theron provides: the whole job, none of the bloat.
