What is One2Tree?
In order to improve our technology, we need to understand how people perceive and judge other people.
Therefore, we created the One2Tree game. In the game, you can rate videos of people in very different contexts. By rating these videos, you not only support us, but you also support the rainforests of Brazil, because for each finished game, our cooperation partner  'One Tree Planted' will plant one tree in Brazil.

Why participate?
As a Startup everything is rare (time, money, etc.).

By participating we offer you free access to our upcoming beta version.
Basically, in exchange for your time we give you access to our technology.
You don't only help us but also yourself and other people who eventually benefit from the technology once it is out.
Moreover, you support the environment by actively contributing to our partner OneTree planted.

We recommend Android users to open the One2Tree game in Chrome.
