This app was created in a minimalistic yet extremely powerful way for language learning. Speech-to-text is practically perfect, corrections are on point. I can even say a word in English when learning German and it will recognize it and give me the word I was looking for. I purchased the annual subscription immediately since I understood that the chatGPT queries are unlimited that imposes costs by itself. The only thing I could think of improving would be sometimes having prompts. Right now it’s up to the user to ‘steer’ the conversation, and the bot can get a little boring with its responses. If you don’t have ideas on what to talk about.
