THE PRODUCT AND ITS DEVELOPER
A notebook that keeps the context.
Otriva is developed by Leon Karim Valentin. The product idea is to keep notes, questions, and explanations together, so that an answer remains beside its source when you come back to review.
For iPad with iPadOS 26 or later. Ages 16+. Current app interface in German. No separate Otriva account.
