Desired outcome: the user learns match verbs with their conjugated form, for both tenses and conjugations.

E.g. in German:

App provides: Essen, user must select Gegessen.

App provides: You Lie, user must select Du Liegst

This could be easily integrated into the existing card matching feature, where the user selects the same word in each language. That could allow you to get it out faster, and iterate into a standalone mode or game later on. The card matching game could be about pairing the conjugations.

Risks might be that the user must have some control over the tenses they see. Niche tenses like Präteritum in German are not as useful as the Perfekt, or the Vorgangspassiv, for example. This is a weakness of the AI feature - when asked to create a story it might not use vocabulary of an appropriate level or stage of the traditional learning journey.

I hope this would be an easy development idea for you. If the word in the card deck is a verb, then maybe add an option to learn the various conjugations of that verb e.g. present, future, imperfect and the various groupings e.g. 1st person, 3rd person, plural etc

Instead of a translation, the cards have the person and verb and the back shows the conjugated verbs. Because using translation does not work when the translated language (like English) does it have many conjugated forms

When we add verb in german language, App should Show All types of verb(future, perfekt etc.)

It would be very nice if when adding a verb when learning German, the programme itself would pull up the three verb forms. This is especially useful if they are irregular verbs.
