Lumbra is a personalized back pain recovery platform that transforms rehabilitation into an intelligent, adaptive experience. The app combines AI-driven workout programming with comprehensive progress tracking to help users overcome back pain through structured, personalized exercise routines.

When our client approached us with the vision for Lumbra, they wanted to create more than just another fitness app—they envisioned a comprehensive recovery companion that would adapt to each user's unique back pain challenges. Understanding the sensitive nature of pain management and the importance of personalized care, we committed to building a platform that would be both medically sound and deeply user-centric.

Creating an effective back pain recovery app required solving several complex problems:

Personalization at Scale: Each user's back pain is unique, requiring individualized workout programs that adapt to their specific conditions and progress

Content Management Complexity: Healthcare professionals needed an intuitive way to create and manage exercise libraries, workout programs, and day-wise plans without technical knowledge

Engagement & Consistency: Back pain recovery requires sustained commitment—we needed to build features that would motivate users to maintain their daily exercise routines

Cross-Platform Delivery: The solution needed to work seamlessly on both iOS and Android while handling media-heavy content efficiently

We built Lumbra using Flutter to deliver a consistent, high-performance experience across iOS and Android:

An interactive questionnaire to assess users' specific back pain conditions

Behind-the-scenes AI analysis to generate personalized workout programs

Smooth, intuitive flow that builds user confidence from day one

Daily & Weekly Streaks: Visual tracking of consecutive workout days to build habits

Freeze Mechanism: Smart auto-freeze feature that protects streaks during legitimate breaks

XP Points System: Rewards users with experience points for completing each exercise day

Progress Dashboard: Real-time insights into recovery journey and achievements

Single Flutter codebase delivering native-feeling experiences on both platforms

Smooth animations and transitions that enhance user engagement

Optimized media playback for exercise videos and demonstrations

We developed a comprehensive ReactJS-based dashboard that empowers content creators and healthcare professionals:
