I've been using it while playing Where Winds Meet, and when I get lost in the game, I passively give back to my community. Fitting for the month of December.

It's called Canopy and is on Overwolf. You earn points while you play any detectable game and donate to tree-nation.com or a nonprofit of your choice. While you play, ad revenue generated from the app is used directly to fund these donations.

I'm working on a standalone open-source executable, which will detect any installed steam game (and other games too)

I also just implemented nonprofit choice, as well as a holiday calendar to earn unique stickers, borders for an overlay window (window display toggleable), themes for the app, and boosts to increase your overall point gain.

The main window shows ads on a secondary monitor. You can minimize it, but without ads showing, there are no funds being created and no donations being made.

As an aside, that Where Winds Meet game is something else, I gotta say.
