Earnest - Nachhaltig leben

Earnest is a sustainability app that helps you learn, act, and make an impact in everyday life through the three pillars: Learn, Act, and Impact. In Learn you access a large database of practical tips—from saving energy and water to conscious consumption and DIY ideas—designed to be simple and actionable for users at home, at work, or on the go.

In Act you can take on challenges and join community competitions with leaderboards. Completing challenges earns points that unlock sustainable rewards and deepen your commitment to climate protection. In Impact you can fund projects such as tree planting or ocean cleanup, or enable your company to sponsor initiatives. A business version adds employee quizzes and a CO2 calculator for sustainability reporting, while the app itself is available in German and English.
