Is there an app that makes it easy to record Korean words?

Hello! While studying Korean, I wanted to record words, but I couldn't find a simple and clean app that suited me, so I decided to create one myself. With this app, you can select new Korean words or sentences to save directly in the app, and it also supports voice input. Additionally, you can analyze the components of a sentence, and it provides the ability to export or import words for data backup. Currently, it is only available on iOS, and I think it will be especially useful for those learning Korean as foreigners in areas like Gangnam or Hongdae. If there are people with similar needs, I wonder if this app could be helpful. 😊
