Muellabfuhr is a free iPhone app developed by Patrick Hesse that helps you stay organized with your trash pickups. With this app, you can set a customizable day to receive reminders about when your waste will be collected. Additionally, you can view future pickup dates for your trash bins.

One of the standout features of Muellabfuhr is that it doesn't require any registration. The app comes preloaded with trash pickup schedules, making it convenient for users to get started right away.

Green-IT is an important aspect of this app. The server that handles the pickup schedules is hosted in Germany and operated by a provider that uses green energy. The electricity used to power the server is generated from hydropower, which is considered one of the most environmentally friendly forms of energy production.

In the app's settings, you can select your location to automatically receive reminders about your trash pickups. You can customize the number of days in advance and the time at which you want to be notified about upcoming pickups.
