驊曖體育: Multi-Branch Yoga Studio Operations System Classes, instructors and branch data in one system, built by the same team from version one to version nine.

JoinX built an operations system for 驊曖體育, a yoga studio chain, connecting head office, branches and instructors through a back office, a web front end and iOS and Android apps. Class booking, check-in and attendance all happen in the system, and class performance at each branch is calculated by the system and shown on dashboards instead of being tallied by hand. We began working together in June 2020 and have kept releasing new versions as operations required. An ongoing maintenance contract has been in place since 2025; over six years in, the system is on version nine.

驊曖體育: Multi-Branch Yoga Studio Operations System

Background

Project Background

驊曖體育 runs a chain of yoga studios with multiple branches, a wide range of classes and many instructors. Before the system, classes, attendance and performance at each branch were mostly tallied by hand, which made management costly and left the figures out of date. 驊曖體育 asked JoinX to build an operations system combining a back office, a web front end and iOS and Android apps, designed around how its studios run. It handles class booking and studio check-in and shows how each branch and instructor is doing, so managers can plan classes and allocate resources based on actual figures. JoinX began development in June 2020 and has kept releasing new versions as operations required: version six from October 2024, discount codes added in version seven, version eight in September 2025 and version nine in June 2026. An ongoing maintenance contract has been in place since 2025, so JoinX also looks after the system after each release.

Challenges

Project Challenges and In-Depth Assessment

Building a multi-branch management system, we first worked through how data is defined and how people would use it:

Consistent metric definitions

Across branches, key metrics such as average class size and attendance rate need one rigorous, shared calculation, so head office and branches never work from different numbers.

Different roles, one set of data

The system serves both head office and branches, and instructors, the front desk and members need to see the same data. Each role should see what it needs in the same interface without clutter. Member records are personal data, so access rights and retention had to be planned in line with Taiwan's Personal Data Protection Act.

Easy for non-technical staff

Most administrative and management staff are not technical, so the system had to be intuitive enough to use without lengthy training.

Solutions

Strategic Solutions and Highlights

We took a modular architecture and visual decision-making approach, then added features release by release as operations required:

Modular back-office architecture
Classes, instructors, branches and statistics are separate modules, which makes maintenance easier. Because studio rules change as the business evolves, the modular design lets the system keep evolving and leaves room for new service types or locations.
Multi-dimensional operations dashboard
Managers can switch between instructor, branch and class views to see key operating metrics at a glance and compare how branches are performing.
Metric definitions built into the system
Clear calculation rules are documented inside the system, cutting internal back-and-forth and making the figures more credible in decision meetings.
Interaction designed around decisions
The system goes beyond listing data to emphasise comparisons and trends, using charts to help managers decide where resources should go first.

Tech stack

Technical Implementation & Framework

The back office, web front end and apps share one set of data, keeping all three in sync:

Native App Development: Swift / Kotlin

A stable mobile experience for members and instructors. iOS is built natively in Swift and Android in Kotlin, making full use of each device.

Native iOS and Android development
Smooth experience optimised for mobile devices
Hardware adaptation and stable operation

Frontend Web Development: Vue.js

A consistent, intuitive management back office across devices. Built as a Vue.js single page application (SPA) for smooth page transitions and real-time data, helping managers handle complex scheduling and operations.

Smooth, intuitive SPA management interface
Responsive layout across devices (RWD)
Frontend data processing and integration

Backend System Development: PHP

The data core is built in PHP. It handles large volumes of member data and calculates the high-frequency booking credit deduction logic precisely, keeping credit and class data accurate.

High-frequency booking credit deduction logic
Processing large volumes of member data
Rigorous business logic and API design

Impact

Project Results & Value

Since we began working together in 2020, the system has supported 驊曖體育's day-to-day operations:

Automated statistics replace manual reconciliation

Class booking, credit deduction, check-in and attendance all run in the system, and automated statistics replaced manual reconciliation and report preparation, letting the admin team focus on members.

Class planning based on data

Attendance and class popularity figures guide adjustments to classes and peak time slots, so class planning rests on actual data.

Over six years together, now on version nine

We began in June 2020 and have kept updating the system as operations required: discount codes in version seven, version eight in September 2025 and version nine in June 2026. Through years of releases the architecture has stayed stable, and with an ongoing maintenance contract since 2025, the same team handles development and maintenance, so new operational needs go straight into the next release.
