Chance

About the App

CHANCE is a revolutionary social media platform that connects individuals and businesses passionate about conscious and sustainable lifestyles. The app creates a dynamic space where environmental awareness meets social impact, turning everyday interactions into opportunities for positive change.

When our client first approached us, she had a clear vision: create a social media platform that would unite eco-conscious individuals and businesses committed to sustainable living. However, her previous development attempt had been challenging—multiple App Store rejections led to frustrated resubmissions without addressing the underlying policy issues.

Understanding her struggles and the importance of her mission, we committed to transforming this vision into reality. Rather than building upon the problematic previous version, we decided to start fresh with a solid foundation.

The Challenge

Creating a successful social media platform for sustainable living required overcoming several obstacles:

• App Store Compliance: Previous version faced multiple rejections due to policy violations that weren’t properly addressed
• Complex Social Features: Building a feature-rich social platform with posts, comments, messaging, subscriptions, and real-time notifications
• Business & User Balance: Creating distinct experiences for both eco-conscious consumers and sustainable businesses
• Subscription Management: Implementing robust in-app purchases and subscription handling across iOS and Android
• Performance at Scale: Ensuring real-time responsiveness with growing user interactions and content

The Solution

Strategic Fresh Start with UI/UX Focus

We made a critical decision: start completely fresh rather than inherit technical debt. We dedicated significant time to the UI/UX phase, collaborating closely with the client to create an exceptional user experience that would:

• Meet all App Store and Play Store policy requirements
• Provide intuitive navigation for social features
• Create distinct, valuable experiences for individuals and businesses
• Ensure accessibility and engagement

Result: Due to our deep knowledge of store policies and meticulous preparation, the app was approved on the first try with zero resubmissions needed.
