Help us help science. Twitch Crowdsourcing is our approach to coordinating millions of micro-contributions in spare seconds. We need your help to demonstrate that it's possible.
Each time you use your phone, answer a roughly one-second question about your surroundings. How many people are nearby? Are those people energetic or lethargic?
To join the team, download our Android app and use it to replace your phone's default lock screen. Twitch will appear after your security unlock if you have one.
You've helped us collect the crowdsourced activity map below. Updated as you use Twitch!
