Worldview Profile
Build a profile of the user's philosophical and worldview beliefs.
A structured picture of what somebody actually believes across ethics, knowledge, free will, meaning and politics, built from their answers rather than from a personality quiz. It names the traditions their answers sit closest to, and where they are internally inconsistent.
What a v1 does5 features
- A profile across several philosophical dimensions, not one axis
- The traditions and thinkers each position sits nearest to
- Tensions between answers surfaced rather than smoothed over
- Retakes free, with the change tracked
- A shareable summary that is not a personality label
The market
Day One charges $34.99 a year, and reflection products monetise annually rather than monthly. This sells once, at $6 with free retakes: about what two months of Day One costs.

Why this audience
This audience enjoys being categorised intellectually rather than by personality quiz - they want to know which tradition they have been reasoning inside without knowing it. They have the vocabulary and the patience for a real profile. Almost nobody else does.
Before it can launch
No licence, certification or data agreement stands between this and a launch — app-store review and an ordinary privacy policy aside.
How the pricing works
One payment for the full profile, and retakes are free. How the profile moves over a year is the interesting part, and charging for the second sitting suppresses the only data point that makes the first one worth anything.

Opens on the price this idea was costed at, $6.
A quarter is one purchase every four years; twelve is monthly.
1,000 paying — 0.037% of 2.7M followers — × $6 × 2 purchases a year = $12,000 a year
Fifty thousand paying users is the ceiling every one of these pages is drawn against, not a forecast. It opens at a thousand, the bottom of the range, so the first figures you see are the modest ones. What the cap buys is comparability: the same range on every app, and the percentage of the audience it takes as the number that moves.
