Test a 3-day against a 7-day free trial, US and abroad separately
Near-even in the US; 7-day converted ~2% better internationally (early data)
Mixedpaywallexperimentation
What they did
A/B test of 3-day vs 7-day trials, also varying the reminder (2 days vs 1 day before the trial ends). Segmented US vs international. Next: check usage on days 4-7 of the 7-day trial, since shorter trials save AI voice costs if conversion and ARPU hold. Android users are more sensitive than iOS.
What happened
US: conversion differs 0.3-0.7%, ARPU ~20 cents, 3-day cancel rate 5-7% higher. International: 7-day ~2% higher conversion. Preliminary.
In their words
The Superwall Podcast · Morrie Schonfeld - How I built a $500k/mo ai app (so you can just copy me)“So like so far, conversion like really mildly different in the United States on 7 versus 3, like point uh 0.7 to 0.3% difference.”
“Internationally, if we look at 3-day versus 7-day, conversion rate was a lot different. It was like 2% difference. 7-day was 2% higher.”
“Like you'll get notified 2 days before your trial ends versus 1 day before your trial ends, and like that leads to a difference in conversion.”
