TrainerCheck vs Spreadsheets & WhatsApp
This is the real comparison for most independent trainers: not another platform, but the free system you're probably using right now. It costs nothing — until your roster grows and the manual work grows with it. Here's what actually happens as that happens.
Be honest about what this costs you
A spreadsheet and a group chat (or a thread per client) genuinely work for a handful of people. There's no shame in it, and if that's you with 2-3 clients, you probably don't need anything else yet.
But "free" isn't the same as "no cost" — it just moves the cost from your card to your Sunday evening. Every client you add is another chat to open, another row to update by hand, another person you have to remember to chase. The software is free. Your time isn't.
The maths on a normal Sunday
Say it takes 5 minutes per client to message them, wait, copy their numbers into a sheet, and reply — a fair estimate for a quick weekly check-in done properly, not rushed. At 10 clients that's under an hour. At 25 clients, it's over two hours — every single week, on top of the sessions themselves.
That time doesn't buy better coaching. It buys data entry.
What actually breaks down as you grow
| What happens | Spreadsheet + WhatsApp | TrainerCheck |
|---|---|---|
| Sending the weekly check-in | You message every client, one by one | Sends itself, on your schedule |
| Chasing someone who didn't reply | You have to notice, then remember to follow up | An automatic reminder goes out for you |
| Spotting a client going quiet | Buried three weeks back in a chat thread | Flagged on your dashboard automatically |
| Where the history lives | Scattered across chats and spreadsheet tabs | One dashboard, one record per client |
| If you lose your phone, or a client blocks you | That client's whole history goes with it | Nothing lost — it's saved for you |
| What it feels like for the client | Homework in a group chat | A 60-second link that feels like a real program |
| Monthly cost, any number of clients | £0 — plus your time | Flat £25/mo |
So which should you use?
Stay with spreadsheets & WhatsApp if: you're coaching a small handful of clients, the manual check-in is a personal touch you enjoy, or you're genuinely not ready to spend anything on software yet. None of that is wrong.
Switch to TrainerCheck if: Sunday nights are eating an hour or more of real time, you've had a client go quiet without noticing until it was too late, or you want check-ins to look and feel like part of a paid program — without you doing the manual chasing and copying every week.
Common questions
Is TrainerCheck worth paying for instead of a free spreadsheet?
It depends on your roster size. A spreadsheet and WhatsApp genuinely work for two or three clients. Past that, the manual work — messaging each client, copying their numbers in by hand, chasing the ones who didn't reply — can cost an hour or more every week. TrainerCheck automates that for a flat £25/month.
Can TrainerCheck replace WhatsApp check-ins?
For the check-in itself, yes. It sends each client their weekly check-in automatically, reminds anyone who hasn't responded, and keeps every answer in one dashboard instead of scattered across chat threads. You can still message clients however you like.
How much time does automating client check-ins save?
As a rough guide, if a manual weekly check-in takes about five minutes per client, that's over two hours a week at 25 clients. Automating the sending, the reminders and the record-keeping removes most of that. Actual time saved varies by roster size and habits.
What happens to my client history if I lose my phone?
With WhatsApp or chat-based check-ins, a lost phone or a client blocking you can take that history with it. TrainerCheck stores every check-in in one place, so nothing is tied to a single device or chat thread.
When should I move from a spreadsheet to check-in software?
When Sunday admin starts eating an hour or more, when you've had a client go quiet without noticing until it was too late, or when you want check-ins to look and feel like part of a paid program rather than homework in a group chat.
Keep your Sundays. Lose the admin.
