Momingo's 2 tactics

When someone closes the paywall, give them a free week of Pro anyway
Paywall closers who paid rose from 0.4% to 4.5%

Onboarding is benefit-led (not features) with social proof on every screen. Tapping the free trial shows 'Welcome to Pro'; tapping X shows 'Enjoy a week of Pro on us' and walks the user through Pro features. During the week, Pro-labelled notifications (bus/train alerts) show what goes away without a subscription, and ads are removed. Before the week ends the app says it's about to end, then offers a discount.

Judge ad spend on 3-month customer value, not first-month return

Rather than month-one ROAS (spent $1,000 this month, made how much this month), evaluate how much a cohort makes within three months against CAC, which allows paying a higher CAC.
