90% of users abandon an app after only 2 weeks.
Why?
❌ Generic apps that don't reflect the brand's premium level
❌ Complicated or frustrating user experience
❌ Lack of integration with business needs
❌ Zero retention optimization strategy
Result: leads that don't convert, customers who drop off, and
LTV well below potential.
