About

I'm Rohan. I build ρ1.

ρ1 makes focused tools for people preparing for what matters to them — an exam, a new skill, a change they've been planning. The kind of person who takes their own time seriously and would rather be ready than lucky.

What I'm building

Right now: PMP Prep, on iOS and at pmp.rho1.ai. Flashcards that schedule themselves, a mock exam at the real 180-question length and domain weighting, and a readiness score that tells you where you stand rather than where you'd like to be.

The free single-exam flashcard apps — PMP, CFA, ITIL and the rest — are being rebuilt, and they'll be listed here again when they ship.

How I build

One thing done well, and your time and attention respected.

On data: PMP Prep collects what it needs to sync your progress between your phone and your browser — that is the whole point of an account — and nothing beyond it. No ads, no third-party analytics, nothing sold. The details are at rho1.ai/privacy. The free flashcard apps are different: they have no account and keep everything on your device.
