“A free trial in our calendar app is important because they've got to get through a full week to see the value. But in our weather app, there's a big storm coming and they just want to use the app for that storm period — a free trial might not convert well.”

Free trial strategy must match the app's usage rhythm, not just the calendar

WeCal needs a seven-day trial because users need to experience a full week to see the agenda view's value. The weather app faces the opposite problem: storm-chasers want a single-session peak and leave. The same seven-day trial that converts calendar users repels weather users. Trial design must be derived from the core usage moment, not copied from another app.
