Donate whenever you procrastinate.
Plenty of Chrome extensions try to stop you from visiting procrastinatory websites. However, I inevitably wind up visiting the site on my phone or deactivating the extension. So instead of literally blacklisting the websites I frequent, why not make myself aware of my habits and do some good for the world?
Sign up, blacklist some websites, and then every time you visit one you will donate 10 cents to charity. Your card will get charged every week, and you get to choose which charity to give to. Pick from Girls Who Code, The Red Cross, and Watsi.
You get to set your weekly donation maximum. Your credit card is safely handled by Stripe. And you get notified every time you procrastinate. Try it out, read more (zachschnell.com/donate/) or check out the source code (github.com/zchr/donate-extension)!
