Frequently Asked Questions
Who do you use for Merchant Services?
Monstro-X uses Stripe for payments. We support both ACH and credit card payments. You have the option of passing the transaction fees to your customers if your state allows it.
What types of schools, gyms, or studios is this for?
Monstro‑X works for any group-class business—fitness, martial arts, music, dance, coding, cooking, daycare and more. It’s fully customizable to your business. I'd recommend booking a demo to see it in action.
How does it work?
We use systems based on behavioral psychology to help you enroll more students and retain them longer so you can focus on what you do best - teaching!
How is Monstro‑X different from other gym or member management software?
Most membership software tracks payments and attendance—but that’s where it ends. Monstro‑X is built to help you grow. It’s the first gamified member management software that uses behavioral psychology to boost retention, drive referrals, and keep members engaged—just like the social media apps they can’t stop using.
Is there a contract or setup fee to use your membership software?
No. All plans are contract-free, with no setup or onboarding fees. You can cancel or change your plan at the end of any 4-week billing cycle.
Does Monstro-X support unlimited members?
Yes! All plans include unlimited members, unlimited staff, and unlimited use of all features.
