The members you're about to lose are already in your data.

Coretex reads the scheduling data your gym already has and prints what it finds: who is drifting toward the door, what money is sitting uncollected, and which of your staff actually keep people. Two pages. Names on them. Then an email every Monday.

It starts with a paid diagnostic on your own data. $2,500 to $5,000, credited in full toward year one.

Departing members were flagged far more often than a control group of members who stayed. In your report, this paragraph has names in it: and would be the first two calls to make.

This is the layout, not a leaked report. Every figure on it is redacted, including mine. Yours gets your numbers and your names. The black bars are the point.

The problem

What this actually costs you, quietly, every month.

01

They don't cancel. They fade.

Almost nobody quits outright. Attendance thins first: a week skipped, then two, then a month that nobody notices because the payment is still going through. By the time it's obvious, they left weeks ago and the conversation that would have kept them is long past.

Graded weekly
02

The money goes quiet before it goes missing.

Sessions delivered and never billed. Packages paid for and never used. Balances running to zero with nobody asking about the next one. None of it looks like a problem on any screen you own, because no screen is built to ask.

Named list
03

It is not the same across your staff.

Two people with the same schedule and the same rooms keep clients at different rates. Everyone in the building can feel it. Without measuring it, it stays a feeling instead of a number, and you manage it accordingly.

Scorecard

All of it hides in data you already collect. Coretex reads from Vagaro, Mindbody, Daxko, Zen Planner, ClubReady, and anything else that exports names and dates. It doesn't replace your system, and it never will.

The churn model, on screen

Every client gets a grade.

This is the screen behind the Monday email: the model grades the whole roster, and you read the bottom of the class.

Client grades updated weekly Product mock · not client data
Sample month 14 flagged 9 contacted 4 came back
F was 3x/week, now 1x weeks
D finished a pack, nothing new on the books weeks
C gap 2x their normal rebuy rhythm
B steady, one skipped week in the last twelve
A same three mornings, every week

The model watches attendance rhythm and package state, grades every client weekly, and the Monday email brings you the red rows. Some flags are false alarms, and the list says which; it says so on every list.

How it works

One export in. A report, the lists, and a Monday email out.

i.

Export and send

One file from the system you already run. If it can export dated attendance, it works. You don't change a thing.

ii.

I run the diagnostic

Two to three weeks on your actual history, then the two-page report and a named working list for each leak, walked through with me.

iii.

Then, every Monday

If you continue, Coretex emails you who moved onto a list and who's worth a conversation this week. Push, not pull. You're told; you never go looking.

How it is tested

A churn claim is only worth something if it was checked against the people who stayed.

I rescore every departure week by week using only what was known on each date, then measure it against a control group of members who kept showing up. The control group is what makes the result checkable, and it is why my numbers come out lower than the ones most vendors publish.

A warning only counts if the model flagged the same member two weeks running. The threshold is set on members who are currently active, because setting it on people who already left makes any model look brilliant. Your diagnostic runs that same protocol on your history and prints your catch rate, your warning time, and your false alarms, with the misses beside the hits.

What this cannot tell you
It can't see life. A new job, a move, an injury, a baby. A real share of departures give no warning at all. No model sees those coming, and anyone who says otherwise is selling.
It's wrong sometimes. Some flagged members turn out to be fine. A flag is the start of a conversation, not a verdict, and every list says how often it misses.
It's been proven on one gym. A serious test, not a universal law. That's exactly why the front door is a diagnostic on your data instead of a promise about it.
It won't tell you what it saves you. I don't publish savings numbers, because I'd be making them up. You know what a member is worth. I leave the multiplication to you.

The diagnostic pays for the software.

The fee's credited in full toward an annual plan. After that it's $297 a month per location. Everyone gets the same product; bigger rosters pay a little more. That's the whole number.

Things people ask.

Does Coretex replace my scheduler or POS?
No, and it never will. Coretex reads from the system you already run. You keep your scheduler, your billing, your front desk workflow. It sits on top and tells you what the data's been trying to say.
Why is the diagnostic paid?
Because it's two to three weeks of real work on your real data, and because the report's worth having even if you never subscribe. The fee's credited in full toward year one, so if you continue, the diagnostic effectively cost you nothing extra.
How accurate is it, really?
Honestly: better than guessing, and not magic. The model is scored against a control group of members who stayed, using only what was known on each date, so the result is checkable rather than flattering. It catches most confirmed departures with weeks of warning, and it is wrong a real fraction of the time. Rather than ask you to trust a number from someone else's gym, the diagnostic runs the same test on your history and reports your figures, misses included.
