Why: the goal or problem

Imagine a personal notebook for saving and finding notes. Everyone needs useful basics, while PDF export costs extra to provide.

How: work toward a solution

A fictional personal notebook starts with free editing and locked PDF export. Try each feature, advance the shared three-day clock, then explicitly upgrade: editing stays free, while upgrading unlocks export. Unlike the trial, passing day three does not remove free editing. No money moves; prices, taxes, fees and refunds are omitted.

A lasting free tier with optional paid features.

What: the concept

Freemium keeps a usable free offering while charging for enhancements. The boundary is functionality or allowance, rather than a temporary evaluation deadline.

Fund the free tier sustainably; combine with subscriptions or non-consumable upgrades.
