Overview
Running a gym involves more moving parts than most people realize. Between managing member renewals, scheduling classes, coordinating trainers, and tracking payments, gym owners often find themselves buried in admin work instead of focusing on their community. Our client operated a growing fitness center with multiple locations and needed a unified platform to replace the patchwork of spreadsheets, booking tools, and manual processes they'd been relying on.
We built them a full-stack gym management app: web-based for staff and owners, mobile-friendly for members.
The Challenge
Gym management software tends to be either too generic or too expensive for small to mid-sized operators. Our client needed something purpose-built for their workflow: multi-location support, flexible membership tiers, a class booking system that handles waitlists and capacity limits, and trainer scheduling that accounts for availability and certifications.
The harder challenge was the member-facing experience. Members needed to be able to book classes, manage their own accounts, and view their attendance history without calling the front desk. That meant building a clean self-service layer on top of the admin platform.
What We Built
We built the platform as a Next.js web app with a mobile-responsive member portal, backed by a PostgreSQL database and a Node.js API layer. Gym staff get a dashboard that surfaces daily check-ins, upcoming class capacity, expiring memberships, and outstanding payments at a glance.
The membership engine supports tiered plans with different access levels, automatic renewal billing via Stripe, and pause or cancellation flows that don't require staff intervention. Class scheduling lets admins create recurring sessions, assign trainers, and set capacity limits, and members can browse, book, join a waitlist, or cancel with a few taps.
Trainer profiles track certifications, availability windows, and assigned classes, making scheduling decisions straightforward. Attendance is logged automatically at check-in using a QR code scan at the door. Owners with multiple locations can manage everything from a single admin account, with per-location reporting on revenue, attendance trends, and membership churn.
