About FolioStuff
FolioStuff is a free, no-login collection of tools and calculators built for people who take their investing seriously. No ads, no paywalls, no fluff - just useful stuff.
What it is
The core of FolioStuff is a growing set of homegrown tools and calculators - things that are annoyingly hard to find elsewhere, or that exist but look terrible and are painful to use. Every tool is built to be fast, mobile-friendly, and actually useful in the moment you need it.
Alongside the tools, FolioStuff also acts as a curated directory of the best stock market resources around the web. Instead of Googling the same sites every time, they're all in one place - screeners, charting platforms, sentiment indicators, economic data, and more.
The goal is simple: give traders and investors a single place to do quick math, make sense of their positions, and jump off to whatever else they need.

Who made it
FolioStuff is a side project by Chris Ray. Built because these tools didn't exist in a form worth using, so I made them. If you have ideas for tools you'd like to see, reach out on X (@itschrisray).
