The online library app (Onleihe app) works on the device. The PocketBook Era Color supports the Onleihe app, which is pre-installed and enables direct access to the lending service. This allows you to conveniently use and download eBooks from the eLibrary. The Onleihe app is specially optimised for PocketBook e-readers and offers reliable and convenient use of the online library.
According to my experience and because I once bought and returned it myself, I can say one thing: No.
Either you take Amazon Kindle directly, so that you have Kindle ex works, but you can only use Kindle and no other suppliers. Or you can get an e-book that runs Android, e.g. Onyx Boox, which allows you to use Kindle, Google Books, your own tools (Onyx app) etc. This is possible because you can download apps directly from the Google Play Store.
Unfortunately, I couldn't find a suitable pen in our shop. The manufacturer also has no information on a suitable pen.
The question remains in the Community. Other members may still have suitable information.
Hello, no, there is no app store. However, there are pre-installed programmes and libraries such as the Bond and PocketBook's own shop. As cloud storage there is Dropbox and the own PocketBook Cloud. And there is also a lame browser, but I don't think the device is really intended for surfing the internet ;-)
Hope the information is useful
