Nowadays, I feel like we are so inseparable from our phones that we might as well make use of them.

I gathered a list of the Top 11 green apps to download and have on your phone. All the apps are free, with some in-app purchases but you can still make use of them with free options. The list offers apps that help reduce waste, promote renewable energy, second-hand electronics, and overall sustainable living. When I was living in London, my favourite apps were ‘Too Good To Go’, ‘Olio’ and of course ‘Happy Cow.’I gave away and sold so much food and items with the Olio app, got some goodies with the TGTG and found incredible vegan places with the Happy Cow app.
