An app to fight climate change

The story so far…

When I learned that beef and lamb were far and away the worst climate change offenders, I gave them up. Can design help other people be more aware?

Also, I wanted to practice mobile app design. Can you say, “pre-conceived notion”?

Let’s ask some people about their food habits

I asked friends and family about their shopping habits, food-buying concerns, and knowledge of climate change.

There are two types of people…

There was a split between people who go to the shop with a list, and people who order everything online. I focused on the first group because some of them already used their phones as a shopping list.

Don’t make them feel too bad

I wanted my app to convince people to buy different foods as they wrote their shopping list. I didn’t want to make people feel bad about what they had already bought.

A fancy shopping list

I wrote down all sorts of ideas but settled on a shopping list app. Everyone I spoke to had a shopping list.

Testing, one, two, three

I didn’t test my assumptions, but here’s how I could have:

Bird’s eye view

I pulled out these features from my list of ideas:

An early casualty

I looked into web views on the iPhone for the recipe browser. It turns out Apple doesn’t allow much in the way of “highlight problem keywords as the user browses the web”. So that feature was thrown out.

Does everything fit?

I like to block out mobile screens with grey boxes first.

Just enough visual design to test

Next I added enough visual design that I could test it with people.

The right time to find issues

Usability testing found lots of issues. For example I showed a given food’s climate impact in “KG C02e”. It’s a standard measurement, but most people aren’t aware of it.

Now make it look better

Mockups are fun. And time consuming. Figma components helped save a lot of that time. Here’s an example screen.

A landing page for visual design practice

I designed three landing pages for practice. Here’s one of them.

I didn’t build it

I don’t have the development skills to build an app. Hopefully one day a billionaire sees this case study and wants to fund the development.
