Loyalty over WhatsApp, for businesses worldwide
Retainx for gyms

Catch the member who stopped showing up before they cancel.

Attendance predicts renewal. Retainx flags the drop-off early and pulls members back with the right nudge.

The retention problem

A gym member who stops attending is a member who will not renew, and you usually find out only when the payment fails. Attendance is the leading indicator, but few gyms act on it in time. Retainx watches visit frequency, flags the member whose attendance has fallen off a cliff, and sends a message that re-engages them while there is still a relationship to save.

Attendance drop
Hi Diego, the floor has been quiet without you, two weeks now. Come in this week and your next PT session is free. Want me to book it with Sam?

Strong week, Priya. Four sessions in. One more and you earn a free recovery massage. The squat rack is calling.
Renewal nudge
Hi Lucas, your membership renews next week. Renew early and lock this rate for the year plus two guest passes. Shall I set it up?

Hi Mia, bring a friend who joins this month and you both get a month on us. Who is your gym partner?
A sample insight from your first month

From check-in payments and any card or UPI transactions, plus manual check-ins your staff can log.

Can I message about classes?
