订阅应用的流失消除器

Act as a specialist in reducing churn for subscription-based software. Users sign up for my app, but they cancel before I can generate meaningful revenue. Solve this problem completely: design an onboarding process that helps new users experience the product's value from their very first session, a feature that makes the app part of their daily routine, a re-engagement system that identifies users before they cancel, and a realistic estimate of the reduction in churn over the first 30 days after implementing all of these improvements.
