About this app

Step Zero is your way into a greener home. Small, doable steps for your balcony, garden and windowsill, and every step you complete makes your own scene visibly greener. Solarpunk you can actually do: a future where technology and nature grow together starts at home.

MADE FOR HOW YOU LIVE
Rented flat with a balcony, house with a garden or just a windowsill: Step Zero asks a few quick questions about your home, budget and time and only shows steps that really work for you. Renting? The app tells you where to check with your landlord first.

FOUR AREAS
• Energy: save electricity, cut heating costs, switch to green power, set up balcony solar the right way
• Grow & eat: grow herbs, vegetables in a raised bed or pots, urban gardening on your balcony, rescue food, shop seasonally
• Nature: put up a bird box, build a bee hotel, plant for insects, collect rainwater
• Community: repair, borrow and swap in your neighbourhood

YOUR SCENE GROWS WITH YOU
Every completed step adds something new to your scene: herbs on the balcony, a rain barrel, a fruit tree or solar panels on the roof. You see what you have already achieved, every day.

SAVINGS, HONESTLY CALCULATED
Step Zero estimates how much you save per year, in euros or francs and in kWh. Carefully estimated and explained under “How it’s calculated”, using prices from official statistics for Germany, Austria and Switzerland.

GUIDES WITH SOURCES
Steps come with short guides: why it is worth it, how to do it and what you need. The information is based on public bodies such as consumer advice centres, environment agencies and nature conservation groups. Where rules differ, for example for balcony solar, you see the notes for your country.
Please note: the step guides are currently in German. English guides are on the way.

RIGHT FOR THE SEASON
Step Zero suggests what is in season: from sowing in spring to keeping cool in summer.

PRIVATE AND AD-FREE
No account, no ads, no tracking. The app works offline and your data stays on your device.

Climate action doesn't have to start big. Start with step zero.
