Members cancel weeks before they tell you
The renewal date is not when someone decides to leave. It is when it becomes your problem. Theron puts each member’s 7-day adherence next to their renewal date, so the ones who are drifting are visible while a message from you still means something.

Retention is a data problem before it is a marketing problem
Most tools sold as retention software are outreach tools. They send the lapsed-member email, the “we miss you” campaign, the discount offer. All of that fires after someone has already gone quiet — which is to say, after the decision.
The expensive gap is earlier. Somewhere between six and two weeks before a cancellation, a member stops logging, then trains less, then stops answering. Every one of those is visible if you can see what they are doing. None of them is visible from a door swipe or a billing record.
That is the whole argument for Theron here: the members use the app you give them, so what they do comes back to you as data rather than as a feeling that someone has not been around lately.
The four signals, in the order they appear
Training frequency falling
Not "did they badge in" — did they log a workout. A member who came twice a week and now logs once a fortnight is on their way out, and the gap opens long before anyone mentions cancelling.
Food logging stopping
The first thing people quietly drop is the tracking. It is the earliest signal you get, and it is invisible unless the member is logging in an app you can see.
The plan going stale
A programme assigned three months ago that nobody has revisited is a member being processed rather than coached. The assignment date is on the record.
The renewal date arriving
By the time this is the signal, it is a conversation about price rather than progress. It is on the list so you see it a month out, not on the day.
What it does and does not do
If you came here for automated win-back campaigns, the last two rows are your answer and you should know now rather than after a trial.
| Capability | In Theron |
|---|---|
| Adherence per member, measured | Yes. A 7-day compliance figure on every member, from what they actually logged in the app you give them — not from door swipes. |
| Renewal dates on the member list | Yes. Every membership carries its own renewal date, visible next to the adherence figure rather than in a separate billing screen. |
| Churn and renewal rate across the gym | Yes. The revenue panel reports renewal rate, churn rate, active clients and average revenue per client. |
| Notification when a member changes goals | Partial. You are told when a member updates their goals. There is no rules engine for arbitrary triggers. |
| Automatic churn-risk scoring | No. Theron shows you the signals; it does not compute a risk score and rank your members. You read a falling number and decide. |
| Automated win-back emails or SMS | No. Nothing is sent on your behalf. Export to Excel and run sequences in the tool you already pay for — or, better for retention, send the message yourself. |
Why we do not send the message for you
We could. It is not a hard feature. We have not built it because an automated “we miss you” from a gym is recognisable in about half a second, and the members who most need reaching are exactly the ones who will ignore it.
A message from a coach who noticed, in the week it happened, referring to something specific, is a different object entirely. Theron’s job is to make sure you notice in time to send it.
Not a separate product
Retention is not an add-on module here — it is the same member list, the same dashboard. From €29.99 a month for 10 member seats, any seat count from 10 to 500 at the same per-seat rate. Your members pay nothing.
