Measure how accurate your judgment actually is.

Write down what you think will happen. Rate your confidence (1–5). Later, record what actually happened. LetsMap measures the gap.

Most people never measure whether their confidence was justified.

This isn’t about journaling — it’s about measurable accuracy.

Example
"Raising pricing won't reduce conversion by more than 10%."
Confidence: 4 Outcome: 2 Gap: −2
That gap is measurable. Over time, you'll see where you overestimate, underestimate, or get it right.

What is LetsMap?
A structured system for measuring how accurate your judgment is.

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

Over time, patterns show where confidence diverges from outcome.

No advice. No predictions. No AI. Just math on your own data.
Built for people who make decisions that matter.
• Founders, PMs, operators
• Measurable signal, not journaling
• Your data. Your patterns. Nothing else.
Common categories:
• Work • Money • Health
• Relationship • Personal
