There is a Genki app which was free for a limited time, it may be $10 now or more. When I used first started and was still learning Genki vocab I would go on Quizlet and just type in ‘Genki 1 vocab 1’ and there would always be a deck pre made from someone else with that entire chapter’s vocab
Hmmm, if you really want to simply look at them, why not use the book? The vocab for each chapter is grouped in the back (usually two pages per chapter iirc).
https://www.vocablyfy.com/ is also good. Has vocabulary split into chapters, can combine different chapters, generate flashcards as well as filter by word types. Very solid resource
