FlexFit Austin – Cross-Platform Fitness Tracking App

Project Overview

FlexFit, a premium gym chain with 4 Austin locations, needed a branded mobile app to deepen member engagement, reduce churn, and compete with boutique studios offering digital-first fitness experiences.

The Challenge

Without a mobile touchpoint between gym visits, FlexFit had no way to keep members engaged remotely. This was driving a 32% annual churn rate as members canceled in favour of digital-first competitors like Peloton.

Our Solution

We developed a full-featured fitness companion app for iOS and Android with deep gym integration:

• Customizable workout plans with exercise video library and progress tracking
• Nutrition logging with barcode food scanner and macro/calorie dashboards
• Real-time class booking with waitlist management and push notification reminders
• In-app trainer messaging, form check video submissions, and coaching notes
• Integration with Apple HealthKit and Google Fit for unified health data

Key Results

• Member retention rate improved by 41% in the 6 months following app launch
• App accumulated 12,000+ active downloads within the first 3 months
• Class utilization across all 4 locations increased by 35%
• Net Promoter Score (NPS) rose to 72 from a pre-launch baseline of 44
