Personal Philosophy Journey

Track how a user's views change over time.

Records what somebody believes and shows how it moves. Positions taken today are stored and revisited, so the change over years is visible rather than forgotten - which is usually the only evidence of thinking.

  • Positions recorded with the date and the reasoning
  • The same question re-asked after months
  • Changes shown side by side, then and now
  • Turning points marked - what prompted the shift
  • A long-run view of the whole set of beliefs

Why this audience

This audience has changed their mind about big things and has no record of it, which is a loss they can feel. They think in years, not sessions. Tracking how a worldview actually moved over time is a product only people who take their own thinking seriously would pay for, and that is who is watching.

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.

Is this the one for your audience?

We fund it, build it, and run it. You bring the audience and take a share of the revenue. Nothing to pay and nothing to build.
