The counter-narrative no coaching platform wants you to hear. Why a growing number of successful coaches are abandoning Trainerize, TrueCoach, and Everfit — and what they're using instead.
The coaching app honeymoon is over
There was a window, maybe 2018 to 2022, when every online coach felt obligated to sign up for a coaching platform. Trainerize, TrueCoach, Everfit, PT Distinction -- the list kept growing, and so did the monthly invoices. The pitch was compelling: professional client portals, workout builders, progress tracking, everything in one place.
Fast forward to today and something unexpected is happening. A growing number of successful coaches -- the ones running $15k-$50k/month businesses, not beginners -- are cancelling those subscriptions and moving their entire operation back to Google Sheets.
This is not a regression. It is an upgrade.
The app fatigue problem nobody talks about
Here is what the coaching platforms will never put in their marketing: most of their features go unused. The average coach uses maybe 30% of what they are paying for. Meanwhile, the 70% they do not use creates complexity that slows them down and confuses their clients.
Think about what actually happens when you onboard a new client onto Trainerize. You send them a download link. They create yet another account. They learn yet another interface. Half of them message you on Instagram anyway asking where to find their program. The "professional" experience you were sold becomes a support burden you did not sign up for.
Now compare that to sending a client a Google Sheets link. They click it. It opens. They already know how to use it. No app store. No login wall. No "which notification settings do I enable?" conversation. It works on every phone, every tablet, every laptop, every browser on the planet.
The simplicity is the feature.
Five reasons coaches are making the switch
1. The cost math finally caught up
Let us do the arithmetic that coaching platforms hope you never do.
TrueCoach charges $30-$100/month depending on client count. Trainerize runs $5-$75/month. Everfit is $20-$80/month. At 30 clients on a mid-tier plan, you are looking at $50-$80/month -- roughly $600-$960/year.
Google Sheets is free. Even Google Workspace (if you want custom domain email and extra storage) is $7/month. The difference compounds. Over three years, you could save $1,500-$2,500 -- money that could go toward a course, a mentor, or your own marketing.
And that calculation gets worse as you scale. Coaching platforms charge more as your client roster grows. Sheets does not care if you have 5 clients or 500.
2. Total flexibility, zero feature requests
Every coach who has used a platform long enough has hit the wall: "I wish it could do X." Maybe you want a custom check-in format. Maybe you need a specific macro calculation. Maybe your hybrid in-person/online model does not fit the app's rigid workout-logging paradigm.
With Sheets, you are never waiting on a product team's roadmap. You build exactly what your coaching methodology needs. Custom scoring systems, traffic-light dashboards for compliance, automated macro cycling calculators, periodisation planners that match how you actually program -- all of it is possible without writing a single line of code.
The coaches who thrive are the ones with a system that fits their brain, not the other way around.
3. Your clients already know how to use it
This is the argument that ends most debates. When someone pushes back with "but apps have client-facing portals!", ask them this: how many of your clients needed a tutorial to use Google Sheets?
Zero. The answer is always zero.
Your clients already live inside Google's ecosystem. They use Gmail. They use Google Drive. Many of them use Sheets at work. There is no learning curve, no download friction, no "the app crashed" support tickets.
A coaching platform adds a layer between you and your client. Sheets removes it. Your client opens a link and sees their program, their check-in, their progress -- instantly. On any device. Without installing anything.
4. Data ownership -- the silent dealbreaker
Here is a question every coach should ask: if you cancelled your Trainerize subscription tomorrow, what happens to three years of client data?
Most coaches do not know the answer until it is too late. Your programming history, client progress photos metadata, check-in notes, exercise libraries -- all of it lives on someone else's server, governed by someone else's terms of service. Some platforms offer CSV exports. Many make it deliberately painful to leave.
With Google Sheets, your data is yours. Every spreadsheet, every formula, every check-in response sits in your Google Drive. You can download it, back it up, migrate it, or hand it to a client when they graduate. No vendor lock-in. No export fees. No "please contact support to request your data."
In an era where coaches are building businesses they want to sell or hand off someday, data portability is not a nice-to-have. It is a business asset.
5. AI-readiness that closed platforms cannot match
This is the reason that will matter most in the next two years, and almost nobody is talking about it yet.
Google Sheets works natively with Gemini. It connects to ChatGPT through plugins and the API. You can pipe sheet data into Claude, into automation tools like Make or Zapier, into custom scripts. The entire AI ecosystem treats spreadsheets as a first-class data format.
Coaching platforms? They are closed ecosystems. Your data sits behind proprietary APIs (if they even have one). You cannot ask an AI to analyse your client's training trends if that data is locked inside TrueCoach's servers. You cannot build automated check-in summaries if the check-in data never leaves Everfit's database.
The coaches who will win the next five years are the ones whose systems can talk to AI. Sheets is the universal adapter. Coaching apps are walled gardens.
What a modern Sheets coaching setup actually looks like
Let us kill the obvious objection: "Going back to Sheets sounds like going back to chaos."
Fair concern. A DIY spreadsheet with 47 tabs, broken formulas, and Comic Sans headers is not the answer. Nobody is arguing for that.
A professional Sheets coaching setup looks like this:
- Branded client dashboard with automated progress tracking, traffic-light compliance indicators, and clean data visualisation
- Centralised coach command centre where you see every client's status, upcoming renewals, red flags, and action items at a glance
- Automated nutrition and training engines that calculate macros, progressive overload, and periodisation from your inputs
- One-click onboarding where a new client fills out an intake form and their entire system populates automatically
- Built-in business metrics tracking MRR, retention, referral sources, and capacity
This is not a pipe dream. This is what GSheetsPro was built to deliver -- a production-grade coaching operating system that runs entirely inside Google Sheets. No app downloads for your clients. No monthly platform fees that scale with your roster. No data you do not own.

"But my clients expect an app..."
Do they? Or do they expect results?
Ask ten clients whether they would rather have a slick app with mediocre coaching or a simple, clear system with a coach who actually has time to review their check-ins because they are not wrestling with software.
The coaches leaving platforms report something counterintuitive: client satisfaction goes up after the switch. Why? Because the time they used to spend configuring app settings, troubleshooting client login issues, and formatting workouts inside rigid builders now goes toward actual coaching.
Your clients do not brag to their friends about your app. They brag about their results.
The bottom line
The coaching app era served its purpose. It professionalized an industry that needed structure. But the market has matured, and so have the tools. Google Sheets in 2026 is not the Google Sheets of 2018. It is AI-powered, automation-friendly, and infinitely customisable.
The smartest coaches are not anti-technology. They are anti-unnecessary-technology. They want a system that is flexible enough to match their methodology, simple enough that clients never struggle, and open enough to grow with AI.
If you are paying $50-$100/month for a platform your clients find confusing and your data cannot escape, it might be time to reconsider what "professional" actually means.
