a curiosity series
Little myths about what you already take.
Each one is a single true idea you can play with in ten seconds — and every number on screen is Piru's real model, not a mock-up. Curiosity first; the app comes after.
coffee
Your coffee outlives your coffee.
The caffeine fades, but the metabolite it becomes is still working. A draggable clock and the handoff.
alcohol
Everything else fades in a curve. Alcohol comes down in a straight line.
Zero-order clearance — more drinks make the curve wider, not taller.
grapefruit
A glass of juice can turn one pill into three.
CYP3A4, made visible — and it's oddly specific about which meds it touches.
tolerance
A break doesn't reset you. It resets you in layers.
Three tolerance clocks — fast, medium, deep — and why a week off only feels like enough.
The effect estimator
Watch a dose actually unfold — feeling, energy, compulsion and strain — modeled from published kinetics.
go deeperThe interactive playground
Open every dial — absorption, half-life, transporter affinities — and watch the four lenses respond in real time.
Every myth is one thing Piru's engine does for real, for whatever you take. Meet Piru →
