Custom Metric Log
Create numerical, boolean, or scale-based streams with rapid daily entry.
Personal Data & Analytics Studio
Discover Your Real Personal Leverage.
Log any daily variable and calculate Pearson correlations (r) across 0–7 day lag offsets to discover what actually drives your health and focus.
Correlation Over Speculation
Most self-improvement is based on guesswork. You try a new routine, feel slightly better or worse, and attribute it to the latest change.
MetricBlend provides mathematical proof. By running Pearson r coefficients across multi-day lag offsets, you uncover true cause-and-effect relationships.
Pearson r Coefficient
Measures statistical linear correlation strength from -1.0 (inverse) to +1.0 (direct).
0–7 Day Lag Shift
Uncovers delayed effects that manifest 24 to 168 hours after the input.
Pre-Registration
Prevents confirmation bias by logging hypotheses before collecting data.
Built for Empirical Proof
Designed for practitioners who demand hard data over health trends and generic self-help advice.
Pillar
Custom Metric Streams
Define any daily variable: sleep score, caffeine, deep work hours, mood, or exercise.
Pillar
Pearson Correlation
Calculates mathematical r coefficients (-1.0 to +1.0) and p-values to prove true causation vs. placebo.
Pillar
0–7 Day Lag Engine
