BackUp door Zelfmoord 1813 is a free Android app developed by Zelfmoord1813 that provides tools to help individuals deal with suicidal thoughts, prevent crises, and aid others with suicidal ideation. The app allows users to gather essential contacts, create BackUp cards with activities to calm themselves during challenging moments, and fill their BackUp box with pictures, music, quotes, and future appointments to look forward to. Additionally, it offers a Safetyplan feature to create a step-by-step guide during a crisis.

This app is not a substitute for professional help and should not be relied upon solely in the event of a crisis. It is a part of the Zelfmoord1813 program, which aims to provide support for individuals struggling with suicidal thoughts. Whether used alone or with a friend, a trusted person, or a healthcare provider, BackUp can be a useful tool to help individuals cope with suicidal ideation.
