Contra is a slick app for voicing your most honest opinions. It's pretty simple; you pose a two-sided question and get thoughtful responses and votes from people all around the world. Be careful though: it gets suuuuppper addicting because of the debate mechanism. I've personally spent a few too many hours on it, just trying to prove my point!
Vote Forward makes it straightforward and simple to actually make a difference in the November election. Write letters from the comfort of your own home to swing voters. Letter recipients are ~4% more likely to vote than those who don't get any. 🚀
