Fitness App by LangDev — Gym Management App

Fitness App by LangDev is an internal product demonstrating end-to-end gym management capability, covering both business operations and the day-to-day member experience.

On the public website, visitors can browse five membership tiers (monthly, 3-month, and yearly), a 7-day rolling class schedule complete with trainer names and session duration, personal trainer profiles with their class specialties, and a retail product catalog (drinks, towels, supplements) with real-time stock status. Prospective members can sign up directly through a form connected to the gym team’s WhatsApp.

For registered members, an Android app (built with Flutter) acts as a “remote control” for their membership: QR-code check-in, tracking remaining active days and personal training sessions, paying bills without queueing at the counter, and automatic reminders when membership is about to expire or a class is starting soon. An iOS version is still in development.
