# ⚙️ Simple, transparent and flexible

Electricity shouldn’t cause headaches - that’s exactly why we founded Ostrom.

We continuously work to ensure that our customers always have access to a fair and suitable electricity plan.

Our goal is to make electricity as **simple, transparent, and flexible** as possible - powered by **100% renewable energy** and supported by smart technologies like the **Ostrom app ( [iOS](https://apps.apple.com/de/app/ostrom-energie-smart-gr%C3%BCn/id1566216511) & [Android](https://play.google.com/store/apps/details?id=com.ostrommobile&hl=de))**, helping you save time and effort.
