Check your phone's environmental impact and get insights with myYucuna.

What?

Your phone's footprint. Made visible. In real time.

Every minute on your phone has a carbon cost — but it's invisible, so we never think about

it. Yucuna changes that. It connects to Apple's Screen Time, translates your usage into

grams of CO₂, and shows you exactly where your digital footprint comes from. No guilt, no

lectures — just a clear picture, and simple tools to act on it. Check your impact, spot the

apps that cost the most, and switch on Eco Mode to cut it down.

The challenge.

We spend hours on our phones — and never see the cost.

Digital is invisible. The emissions aren't.

  • 04h37

    The average person's daily time on a smartphone.

  • 02–4%

    Digital tech's share of global CO₂ emissions — more than the entire aviation industry

  • 036g

    CO₂ released by a single hour of video streaming.
