Experiences with the services of the Austrian Pollen Information Service formerly located at the Medical University of Vienna show the multiple benefits of digital health. The pollen diary supports patients/users and/or practitioners in pollen allergy diagnosis. The symptom report generated by the pollen diary shows all the significant positive correlations between personal symptoms and certain pollen types resulting in further indications for pollen allergy diagnosis. The Pollen+ app unites information, forecasts, the pollen diary, and different maps under one roof to empower patients/users to make informed decisions and to support them in allergen avoidance. In addition, pollen forecasts are personalized for those who use the pollen diary. The Ragweed Finder collects reports all over Austria and distributes the ones verified by experts to local and regional authorities to curb the spread of ragweed and thus limit the burden of concerned pollen allergy sufferers and to raise the awareness for ragweed. All services are free of charge, grant easy access (Internet and mobile device/computer required) and comply with the latest General Data Protection Regulation (GDPR). The digital health benefits addressed encompass personalization, (self-) management, cost-effectiveness, affordability, confidentiality, and equity. While the benefits from digital health as illustrated by the experiences described herein are evident, the transformation of digital health continues, and ethical issues should be kept in view.
