Personalization: ML to tailor ads and offers

On the podcast: how Duolingo prioritizes clarity over persuasion on their paywalls, why they offer users multiple free trials instead of just one, and how adding friction to their trial reminder flow actually boosted conversions.

This conversation is shorter than usual and will be featured in RevenueCat’s State of Subscription Apps report. Each episode in this series will explore one crucial topic and share actionable insights from top subscription app operators.

Top Takeaways:

🎯 Prioritize clarity over persuasion on your paywalls
Show users a timeline of exactly what happens during their trial, when they'll be charged, and how refunds work. Duolingo found that removing uncertainty about the purchase process drives more conversions than trying to sell harder.

⚡Shorter trials compound experimentation velocity
Cutting their free trial from 14 days to 7 doubled Duolingo's experimentation velocity. Faster feedback loops let the team kill losing tests sooner and run significantly more experiments per quarter.

🔬Adding friction to trial reminders can boost conversions 
Duolingo tested letting users pick which day they get their expiration reminder. The extra step signaled transparency, built trust that they wouldn't be surprised by a charge, and gave them time to experience real value before deciding.
