Zen Planner is member management software for gyms, martial arts schools, affiliate gyms and fitness studios. It combines membership management, billing, scheduling, attendance and workout tracking, giving fitness businesses a comprehensive system to run operations and support their members.

Membership and billing

Zen Planner automates memberships and recurring billing, handling plans, payments and retail so gyms have reliable recurring revenue with less manual work. It's built around the membership model that fitness businesses depend on.

Scheduling, attendance and skills

The platform manages class scheduling and attendance, and supports skill and belt tracking for martial arts, helping owners monitor engagement and progress and keep members motivated toward their goals.

Automation and retention

Zen Planner includes automated communications and reporting that help gyms engage members, follow up with leads and reduce churn — supporting the retention that drives fitness-business profitability.

Who it's for

Zen Planner is ideal for gyms, martial arts schools and fitness studios that want comprehensive member management — billing, scheduling, attendance and progress tracking — in one system. For a fitness business focused on operations and member engagement, Zen Planner is a capable, established choice.

Why gyms choose Zen Planner

Zen Planner appeals to gyms, affiliate boxes and martial arts schools that want a comprehensive, established system covering everything from billing to workout and skill tracking. Its depth — memberships, scheduling, attendance, belt/skill tracking, automated communications and reporting — makes it a genuine operational backbone rather than just a booking tool, and its long track record gives owners confidence. For martial arts schools in particular, the belt and skill tracking supports the student-progress journey that drives motivation and retention.

Getting started and support

Zen Planner provides onboarding and support to help gyms migrate members, memberships and schedules, and configure billing and automations to match how the business runs. Because it's feature-rich, owners typically invest a little upfront to set it up well, after which memberships, attendance and communications run smoothly. Its automation and reporting then give owners the tools to engage members, follow up with leads and understand their business by the numbers — supporting the retention and growth that keep a fitness business healthy over the long term.

In short, Zen Planner offers gyms and martial-arts schools a deep, established operational backbone — billing, scheduling, attendance, progress tracking, automation and reporting — for owners who want comprehensive control and long-term reliability.
