We revamped CoreMetrics’ brand identity to reflect performance, health, and smart data insights.

Objective:

To enhance the performance, stability, & user retention of CoreMetrics’ fitness tracking app through proactive maintenance, bug resolution, compatibility updates, & ASO improvements—transforming it from a struggling product into a high-performing, user-loved platform.

⚠️ Client Problem

CoreMetrics was an independent fitness tracking app that had launched 9 months before engaging us. It was facing serious issues affecting both user retention and performance:

Challenges They Faced:
❌ Crash rate at 5.7% across Android and iOS
❌ Monthly churn rate over 38%
❌ No in-house development team to handle bug fixes or version updates
❌ App Store Optimization (ASO) was outdated, hurting visibility

✅ Our Solution

We offered a comprehensive App Maintenance package, focusing on four key areas:

What We Did:
1. Performance Optimization
o Reduced app load time from 4.6s to 1.2s
o Improved memory management to prevent crashes on lower-end devices
2. Bug Fixing & Compatibility Updates
o Resolved 100+ logged bugs
o Updated SDKs and integrated Android 14 and iOS 17 support
3. Security & API Monitoring
o Added encryption protocols for user data
o Setup automated API downtime alerts and monitoring with Firebase
4. User Feedback Loop
o Integrated an in-app feedback system
o Launched a bi-weekly hotfix and monthly update schedule
