Green your world. Know your Impact.

WasteNot is a free app that helps you find and share good ideas that can reduce your waste and your impact on the environment! Then watch to see how big of a difference you and your ideas can really make, and see where people are using them worldwide!

WasteNot was built on iOS 2, launched in 2010, and continued to work on all versions of iOS including iOS 8 without a single code change. We are currently working to update WasteNot to support the many changes Apple has made to iOS to allow WasteNot to work on iOS 9 and later.

    Please consider supporting our development efforts and help us keep WasteNot free for the world:

See how much you've helped save the earth!

  • Browse and Search for good ideas (we call them "Seeds") to find simple things you can do to reduce your impact on the environment.
  • Plant Seeds to share your good ideas with people around the world.
  • Water Seeds to let us know that you're using an idea in your life. We keep track of all of the waterings so you can see how much of a difference you and everyone using WasteNot are making. (And your privacy is important to us, so all information you provide to us is anonymized.)
  • Check out our interactive world maps that let you zoom in to see where Seeds have been watered.

Pricing & Donations:

In order to celebrate Earth Day and the SF Green Fest this month, and make a bigger impact by getting WasteNot into more people's hands, we've decided to give WasteNot away for free! We won't be able to keep it that way forever, though, unless we receive donations, or find partners/sponsors to help cover our costs.

If you would like to make a donation, become a sponsor or partner, to help us continue to offer WasteNot for free, Sponsorships@KismetWorldWide.com or donate now via PayPal:

Localized Translations:

Want WasteNot in your language? We do too! We need help translating and figuring out which languages to translate first.

We promise to start by translating into languages spoken in WasteNot's top-selling countries. If you would like to see WasteNot in your language, buy a copy of the WasteNot app now (so we can know your country has interest) and you'll get a free upgrade when we support your language. You can also email us at Support@KismetWorldWide.com
to vote for your language.

If you speak a language fluently and are willing to help us translate, email us at: Translations@KismetWorldWide.com
