## What is Cerne?

Cerne is an app that connects technology and nature to help you measure, understand, and reduce your carbon footprint.
With the power of iPhone augmented reality, you can identify tree species, measure trunk diameter and height, and discover how much CO₂ each tree can capture.

Key Features
	•	Carbon sequestration calculation: Use the camera to record trees and instantly see their potential for CO₂ capture.
	•	Smart mapping: Every entry is saved on a large collaborative map that shows the real impact of each tree and the community.
	•	Individual and collective data: Track your personal contribution and see the combined results of all users in real time.
	•	Biodiversity revealed: Learn about the species present in your region and help expand knowledge about local flora.
	•	Impact reports: Get clear statistics on CO₂ neutralized and estimated oxygen generated from the trees you register.

How It Works
	1.	Capture and identify – Photograph the tree, identify its species, and record diameter and height using the camera and augmented reality.
	2.	Calculate and track – Cerne estimates carbon sequestration potential and oxygen release, creating a history of your positive impact.
	3.	Share and engage – Invite friends and watch the community’s strength grow, with data revealing the total carbon removed from the air.

Why Use Cerne

Every tree counts for the climate. By registering your discoveries, you contribute to a global database that supports environmental research, encourages reforestation actions, and promotes a more sustainable lifestyle.

The app helps you visualize the real impact of small actions, turning every record into valuable information for the planet.

Download Cerne and join a community that believes technology and nature can work together to reduce CO₂ and improve the air we breathe.
