Demonstrations are the lifeblood of democracy. They are the way to influence and be heard. There are all kinds of methods for counting people in demonstrations: Counting heads, locating phones, analyzing drone images,... We came to offer a more accurate count, which verifies that the protester was indeed at the demonstration - in the right place, and at the right time. And counting all of them - both those who came at the beginning and left in the middle, and also those who came after him. And what's more - the count is anonymous: no need to register, no personal information. Just install the app, run it, and press the "Count Me!" button
