The features – your digital logbook in the fight against cancer

The Onkobutler notebook for cancer offers three key features that accompany the healing journey:

1. Krankheits- und Behandlungsverlauf dokumentieren


Record all relevant data about cancer. The diary for cancer patients serves as a logbook for symptoms, medication, and emotions.

2. Berichte teilen


At the touch of a button, the cancer diary generates a report. This can be shared with the treatment team in preparation for consultations.

3. An Medikamente erinnern lassen


The integrated medication reminder ensures that doses are not forgotten. This is a reliable companion, especially during chemotherapy, illness, or rehabilitation.

Please note: Onkobutler supports the treatment team with valuable additional information to tailor therapy to individual needs. The cancer app cannot replace an individual medical assessment. In case of doubt, the assessment of the treatment team should always be sought.

Support for the treatment team

During treatment, patients continuously collect valuable progress data and provide the treatment teams with a compact report based on this data. The report allows the course of treatment to be assessed at a glance, enabling individually tailored therapy planning.

The reports are usually sent to the treatment team by email in preparation for the consultation. The treatment team and patient can agree on the time of data transfer together.

How do you become a user?
