Therapy-assisting app for exposure based cognitive behavioral therapy

Morpheus enables exposure in everyday life, unobtrusively and safely. This improves the therapy effect.


Morpheus should be used by patients undergoing Behavioral Therapy with an in-sensu self-management module.

Morpheus should be used when the attending therapist or doctor incorporates it into the therapy and explicitly advices the patient to use Morpheus.

Medical indications

Morpheus can be used for all exposure-based therapies, especially for the following diagnosis:


  • F43.1 Post-traumatic stress disorder (PTSD)
  • 6B41 (ICD-11) Complex Post-traumatic stress disorder (CPTSD)
  • F40 Phobic anxiety disorders
  • F41 Other anxiety disorders
  • F42 Obsessive-compulsive disorder
  • F43 Reaction to severe stress, and adjustment disorders
  • F44 Dissociative and conversion disorders
  • F45 Somatoform disorders
  • F48 Other non-psychotic mental disorders
  • F60 Specific personality disorders


  • Morpheus is only suited for recording of individual therapy sessions and must not be used for group therapy sessions.
  • Morpheus must not be used if patients have one or more of the following diagnosis (ICD10):
    • G40 Epilepsy and recurrent seizures
    • F00 Dementia in Alzheimer disease



Record Session

With Morpheus, the therapy session can be recorded. The recordings are only stored locally on the smartphone. Highest data security is guaranteed.


The therapy sessions can be played back at any time. Data is collected continuously and can be discussed with the therapist in the next therapy session.



Stress regulation games can be used at any time, e.g. to distract from high stress and to regulate emotions during an exposure.
All skills are designed to appeal to different senses, but are not addictive.


During the use of Morpheus, statistics are collected via questionnaires. These can be discussed with the therapist during the therapy session. In this way, it is possible to react promptly in the event of unusual developments.


Data Security

  • Morpheus stores all personal data such as session recordings and statistics data encrypted on the user’s device
  • Morpheus does not send any personal data to a vacay server or any other server.
  • Morpheus might in future send anonymous app usage data, such as app performance and crashes, to a vacay server
  • Morpheus allows the user to export their user data, e.g. for scientific usage. Morpheus also provides a secure way for user’s to make this data accessible to their therapists or research institute. This process has to be initiated by the user and exports all data at a time rather than doing it in the background.
