The Brief
Stuck with an unstable app draining your resources? See how we rebuilt Cass Olholm's fitness platform from the ground up.
By early 2025, Cass Olholm faced a critical decision: continue pouring money and energy into patching a fundamentally flawed application, or invest in building the platform she originally envisioned. Her iOS app, plagued by architectural limitations from a previous developer, crashed frequently, frustrated members, and restricted her creative programming capabilities through a clunky CMS.
Cass had already experienced PixelForce's stabilisation work firsthand when we rescued her iOS app from constant crashes. That success gave her confidence to make the bold decision to rebuild completely from scratch rather than continuing to apply temporary fixes to broken foundations.
The original app's problems ran deeper than bugs. Poor user flows confused members. The admin interface made simple tasks complicated. The CMS couldn't handle the sophisticated programming Cass wanted to create. Most painfully, Android users remained locked out entirely while Cass hesitated to duplicate a platform she wasn't proud of.
Cass needed more than repairs. She needed a complete reimagination - a platform that matched her ambition, served her community properly, and finally delivered the Android launch her audience had been requesting for years.
Our Solution
PixelForce approached this rebuild with a comprehensive strategy focused on delivering what Train With Cass should have been from day one.
- Ground-Up Rebuild with Flutter: We chose Flutter as the development framework, enabling simultaneous iOS and Android delivery from a single codebase. This strategic decision meant Cass could finally launch on both platforms without duplicating effort or cost. Flutter's performance characteristics also guaranteed smooth animations, fast load times, and native-feeling experiences on both operating systems.
- Member-Centred User Experience: We redesigned every user flow based on how members actually wanted to train. Navigation became intuitive. Workout discovery felt natural. Progress tracking happened automatically. The interface got out of the way, letting Cass's programming shine through without technical friction interfering with the training experience.
- Sophisticated Admin Portal: We built Cass a control centre that simplified her daily operations. Content scheduling, member management, and analytics reporting now happened through clean interfaces that required no technical knowledge. Tasks that once took hours now completed in minutes, freeing Cass to focus on coaching rather than wrestling with systems.
- Powerful Content Management System: The new CMS unlocked Cass's creative freedom. She could now build complex training progressions, create personalised programming variations, and structure content exactly as she envisioned - without hitting arbitrary technical limitations. The system adapted to her creative process rather than forcing her to work around constraints.
- Enterprise-Grade Infrastructure: Behind the scenes, we implemented AWS infrastructure designed for scale. Automated testing protocols caught issues before release. Monitoring systems provided real-time health checks. The architecture anticipated growth rather than reacting to it.
- Seamless Data Migration: For existing iOS members, we handled migration carefully. Progress data, workout history, and personal settings transferred smoothly into the new platform. Members woke up to an upgraded experience without losing anything they had built.
