N=1 Experiment Tracker

Design structured self-experiments with custom metrics. Log daily data, track trends, and compare before/after results. All data stays private in your browser.

Why Self-Experiment?

Personalized Data

Studies show averages. Your body is unique. N=1 experiments reveal what actually works for YOU specifically.

Structured Approach

Define a clear hypothesis, intervention, and metrics before starting. This prevents confirmation bias and cherry-picking.

Compound Knowledge

Each completed experiment adds to your personal health knowledge base. Over time, you build an research-informed protocol.
