You can sort through these suggestions by swiping left or right to indicate whether you already know the word. Words you didn't know can be registered in bulk, with the AI instantly generating all definitions and example sentences for you. -------------------------------------------------------------------------- Recommended For: - Those looking to expand their vocabulary efficiently. - Anyone who wants to save time on manual flashcard creation. - Learners who want to review words at the scientifically optimal time. - Penguin lovers!

Memo Clock is a memory and review application designed for learners. It is suitable for those who really want to keep their knowledge: students who are preparing for the exam, learners who want to sort out the course content, those who need to repeatedly consolidate concepts, formulas, wrong questions and vocabulary, or those who want to build their own long-term knowledge base. Many times, it is not that we don't study, but the notes are scattered in different places, the pace of review is unstable, and the content that we really forget is not found in time. What Memo Clock hopes to solve is the distance between "recording" and "really remembering". Here, you can organize your knowledge into a memo that is more suitable for review. Memo Clock will help you arrange review, review forgotten content, record the pace of learning, and provide more suitable review methods for different stages. You can be more concentrated before the exam, your daily life can be more stable, and you can also complete a little lightly in the fragment time. Memo Clock is not just a notebook or a reminder tool. It is more like a quiet study workbench: helping you store knowledge, organize reviews, check your mastery, and gradually form more sustainable learning habits. You can start from the preset database, import your own content, or share information with your classmates and friends. Whether it's a course, an exam, or a long-term learning goal, Memo Clock hopes to help you move on in a clearer and more stable way. Take down the knowledge and let it come back to you at the right time.
