yes, you can by downloading the software from the tip toi website

Hello, I am currently in dialogue with Ravensburger. They say: You have to change the language of the pen every time (with the computer!). In my opinion, this is an absolutely unnecessary technical (software-based) restriction that Ravensburger has programmed in here. Unfortunately very, very disappointing. If I have any news, I'll report back here.

good day! Unfortunately, this tiptoi the pen hasn't worked for a week! it just doesn't turn on a book, but the button is on! The child is very upset because he really liked it. What do we do now with a broken tiptoi the pen ? the tiptoi the pen only lasted us 5 months.
