See how your decisions turn out.

Write what you expect. Record what happens.
Build a track record over time.

Different from journaling — each entry connects an expectation to a real outcome.

Example
"Raising pricing won't reduce conversion by more than 10%."
Confidence: 4 Outcome: 2 Gap: −2
That gap is measurable. Over time, patterns become clear — where confidence aligns with outcome, and where it doesn’t.

What is LetsMap?
A simple way to compare what you expected with what actually happened.

1. Record what you think will happen.
2. Rate how confident you are.
3. Later, record what actually happened.

Over time, patterns show where your confidence diverges from reality.

No advice. No predictions. No AI. Just math on your own data.
For people who make decisions that matter.
