In RevenueCat’s 2026 app data a hard paywall converts about five times freemium at day 35 (10.7% against 2.1%; its benchmarks post calls that trial-to-paid and its paywall post calls it download-to-paid), with the same one-year retention for yearly subscribers (27% against 28%). Trials of 17–32 days convert about 70% better than three-day trials. Test it deliberately.
