The eRef App, developed by Georg Thieme Verlag KG, is a free-to-use lifestyle medical app that operates offline on Android 9.0. With this app, you can now access the Thieme Knowledge Portal for Physicians offline, even while on the go. The app is available to anyone with an active eRef trial account, a personal eRef license, access to an institutional eRef license, a subscription to a Thieme journal, or an access code for a Thieme book.

One of the main features of this app is the ability to load your e-books and e-journals on your smartphone, so you can read them anywhere and anytime. Additionally, you can activate your personal journal subscriptions in the eRef app and use the cockpits to research differential diagnoses, treatments, and much more.
