Atopic dermatitis is a chronic inflammatory skin disease associated with allergic diseases and can lead to significant disease burden and loss of quality of life despite modern treatments. Digital tools for AD patients include online resources such as web searches and social media platforms, wearable biosensors (wearables), mobile apps, and new diagnostic tools such as 3D full body scanners and optical coherence tomography. While the analysis of online data can provide insights into the needs and wants of AD patients, the general quality of AD-related online information seems to be low and laced with misinformation. There is still insufficient clinical data validating the clinical use of apps in AD. Digital data, especially from new diagnostic methods, lends itself to machine learning and artificial intelligence analysis. New data is constantly being generated, and algorithms are being created and improved, so there are exciting future perspectives especially for this field in digital tools in AD.
