AI-Powered Challenge & Rewards Mobile Application
Objective:
Develop a cross-platform mobile application prototype based on an existing UI design and integrate it with backend APIs. The goal was to create an engaging platform that motivates users to stay active by completing challenges individually or with friends while earning achievements and rewards.
Challenge:
The client required a scalable mobile application capable of supporting:
- Guided and self-directed challenges
- Social participation and collaborative activities
- Achievement and reward mechanics
- Seamless user onboarding
- Future expansion with new challenge types and engagement features
Activ8 needed to provide a smooth user experience across platforms while maintaining a clean architecture that would support long-term growth.
Solution:
We developed the application from scratch using Flutter, delivering a modern cross-platform experience for both iOS and Android users.
The platform enables users to:
- Complete challenges independently or with friends
- Follow guided activities and structured programs
- Unlock achievements and rewards based on progress
- Track activity milestones through visual progress indicators
- Participate in a socially engaging experience with minimal onboarding friction
Key Features
AI-Enhanced Reward System
The application leverages Firebase AI capabilities to generate personalized visual rewards, creating a unique and shareable experience for every completed milestone.
Frictionless Authentication
Multiple authentication methods were implemented, including:
- Google Sign-In
- Sign In with Apple
- Firebase Phone Authentication
This allows users to join challenges quickly and securely.
Scalable Architecture
A robust foundation was established using modern Flutter development practices and code generation tools, enabling the client to rapidly introduce new challenge types, guides, and engagement mechanics in the future.
