Handfull is an application developed in Flutter to support physicians, in particular, to submit patients to a battery of tests for the monitoring and diagnosis of degenerative neuro-muscular diseases. These tests will then be appropriately examined by automatic and/or semi-automatic analysis of written and vocal tracings. The tests considered refer to different cognitive areas and are based on the patient's abilities in constructive praxis, concentration and language. They aim to facilitate and reduce the time of diagnosis, for patients and their loved ones. This work aims to extend the possibility of a rapid and early diagnosis of these degenerative neuro-muscular diseases.
