Starting today (because this planet is awesome and worth saving) all of the proceeds from a selection of the iTunes App Store's paid apps, plus in-app purchases, are going to the World Wildlife Fund (WWF) in honor of 🌍 Earth Day 🌎.

WWF's projects support the health of forests and oceans, the accessibility of fresh water, wildlife preservation, the reduction of food waste, and the promotion of renewable energy.

There are 27 apps participating in the campaign, which runs through April 24, and here are some of our favorites.

Note: only the iOS versions of the apps support WWF, but the Android apps are linked here, just in case.

1. The Earth by Tinybop ($3, iOS) is an interactive, educational app intended to spark conversations between kids and parents about how our planet works.

Travel through time to see how Earth has changed over millions of years. Investigate how deserts, mountains, oceans, and glaciers were first formed. You'll learn new vocabulary while engaging with the app's beautiful original artwork and unique sound design. The app is offering three new interactive features focused on forest, energy, and water for the Earth Day campaign.

2. Yoga Studio ($4, iOS) includes high-definition video classes, plus a guide to over 280 poses.
