Time recommends using this cute app to track your energy use helps you learn how much energy you’re consuming and the adjustments you can make to evolve a more eco-friendly lifestyle. If you’re good, the polar bear’s iceberg gets bigger.

The app tracks your energy consumption in areas like electricity, travel and food, and within each category, there are suggestions for doing things differently to help conserve energy. Some of the suggestions are simple (like recycling) and some are complex (like installing a high-efficiency water closet). As you take up the suggestions, you accumulate carbon units and can quickly see how much energy you are saving.

A cute visual device — a polar bear perched on an iceberg — depicts your progress. The more energy you save, the bigger the iceberg gets.
