Influx - 2026 Pricing, Features, Reviews & Alternatives

nflux is complete gym management software built on more than 10 years of continuous development, with a core development team that isn't outsourced and experience in fitness technology extending well beyond that.

The platform has been developed and refined alongside real gyms over many years, providing a solid foundation while continuing to evolve as technology and the way members interact with gyms changes.

Manage memberships and passes, payments, classes, courses, appointments, staff, training, communications and reporting from one connected system. Online sign-ups, trials and drop-ins, multi-location management, kiosk check-in and integrated shop features are also built in.

Automation runs throughout Influx, helping reduce everyday administration across member communications, bookings, payments, attendance, appointments and waitlists. Set your own rules and let Influx handle actions such as reminders, notifications, absence and no-show communications, payment follow-up and smart waitlist offers.

Members have their own app for bookings, payments, purchases, waitlists, training and social spaces. Joining and purchasing follows a familiar checkout-style process, making it straightforward for members with different levels of technical confidence. Coaches have their own app for schedules, classes, appointments, attendance, visitors, cancellations and programmed workouts.

Reporting gives gym owners visibility across attendance, memberships, retention, cash flow and invoicing. Influx also integrates with services including Stripe, Xero and Mailchimp.

Influx combines an established software foundation with technology that is continually maintained and upgraded. Core features are included as standard, with pricing designed to adjust with active member numbers — from new gyms through to established and multi-location fitness businesses.
