Mobile App Optimization Software Resources

I want to start a discussion with experts in the mobile app optimization software community on G2, and I’d like to crowdsource opinions especially from those who care about optimizing e-commerce user experience, retention, and conversions. 

Here are my top picks:

• AppsFlyer - Great for deep analytics, attribution tracking, and understanding how users acquired via various channels behave within your e-commerce app.
• CleverTap - Also top-ranked, excels at user engagement, segmentation, and personalized messaging, which can drive retention and conversions in a shopping app.
• LogRocket - Highly rated for usability and insight into actual user sessions, crashes or UX issues; useful to optimize app performance and user flows in an e-commerce context.
• Fullstory - Helps capture user interactions, session replays and bug-tracking to analyze friction points in checkout funnels.
• Pendo - Useful for user onboarding analytics and feature adoption tracking, can help optimize onboarding flows for first-time shoppers.
• Contentsquare - Particularly good when you want data-driven insights into where users drop off, can help improve product listing pages, checkout steps, or navigation.
• VWO Testing - A/B testing across app features and UI/UX elements, helpful to incrementally improve conversion rates or checkout UX in e-commerce apps.
• Heap - Analytics-driven tool for event tracking and user journey analysis, useful to understand user behaviours in an e-commerce flow.
• Kochava - More attribution and marketing-analytics oriented, which may help understand acquisition from different channels, useful for e-commerce growth strategy.

Tools combining analytics, engagement, session insights, and A/B testing best boost e-commerce performance. Which tool improved your conversions or retention most, and why?
