Not quite an app, yet, but Hannah and Liam’s Zero Waste Spot is already awesome! Its an interactive map of zero waste stores all over New Zealand, it is comprehensive and its easy to use. My inner librarian is so relieved! Its sooooo nice to have all this great information in one place – and accessible! And if you see something is missing you can suggest markers so its just going to get better and better.
If you are an app developer and would like to be part of a team working on developing the zero waste spot app Hannah, Liam and I would love to hear from you, email@example.com
The Regional Shopping Guides might also be useful, its a written version of the Zero Waste Spot and they have some extra, non-mappable info.
