Simple & easy to use
The Shop Ethical! app is a great starting place if you're wanting to shop more ethically. The ratings give a broad but good overview of how ethical (or unethical) a company is - ratings are not for products themselves. I use this app all the time to check the 'eco credentials' and ethical nature of the company behind products I'm interested in buying. I find it especially helpful when comparing similar items, it helps me to choose the more ethical one as you see a list of alternatives in each category. Overall I would rate 4* because there's always things that can be improved; I especially find it frustrating that sometimes I can't find ratings for particular companies or brands, so I have to do my own research to find the name of the overarching company. But overall it's a great app and very simple to use, although the ratings could be confusing for someone new to it.
