before you pay.

A note from the developer

I'm a retired software engineer
living with Parkinson's.

I built these apps because I love clean software, I love teaching, and I want every dollar they earn to fund research into the disease I'm living with. Parkinson's affects more than one million Americans and over ten million adults worldwide.

Net proceeds from PartPilot — and any voluntary contributions inside Cognitive Boost — go to The Michael J. Fox Foundation for Parkinson's Research, the world's largest non-profit funder of a cure. I'm not affiliated with the Foundation; I'm one of the millions who believe a cure is possible and want to help fund it.

The 4genera app family

Three apps. One mission.

Each app is designed to be useful on its own — and together they help fund the search for a Parkinson's cure.
