- 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
The market
Day One charges $34.99 a year. Reflection products monetise annually rather than monthly, so $8 a month is materially above the category norm.

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.
