Understood.app — a personal ontology

The feeling is the product.

The software that learns the causal shape of your life and tells you what to do next based on what has already worked for you, specifically.

Four axioms from my own record.

Learning Master Key

0.67

If High Learning

Then Affect +67%, Ambition +65%, Insight +62% (same week)

Learning is not a break from work. In nineteen months of data, it was the single highest-leverage lever on every other life domain.

Exercise × Sleep Synergy

0.57

If High Exercise AND High Sleep

Then Excellent stress recovery

Neither lever alone predicted excellent recovery. Only the combination did. The AND is the axiom.

Belief → Entertainment Lag

0.60

If High Belief in week N

Then Higher Entertainment in week N+2

The week I play well is not the week I schedule play. It is two weeks after the week I engage deeply with what I believe in.

Zero Negative Impact

0.95

If Investing in any one life domain

Then Does not secretly cost another

The axiom with the highest confidence in my ontology, and the one I did not believe until I saw it. No hidden tradeoffs.

What it gives you
Output 1

Dependable predictions

What's about to happen in your life, based on what you just did. Confidence-scored, derived from your own record.

Output 2

Real recommendations

What to do next. Grounded in the axioms you've already discovered.

Output 3

Personal history that improves every day

The record compounds. Every new entry tightens the axioms that power the first two.

If you have been one step below where you know you should be, and you are done waiting — this is where that ends.
