Hi Product Hunt 👋

I built Danny & Jenny on my own in Seoul, and it started with one semester.

As an exchange student in the US, I barely talked with my American roommate. My English wasn't enough, so we never got past hello. But with a Korean-American friend from class whose Korean was shaky, I talked about everything, all semester. I spoke mostly in English and threw in Korean only for the words I didn't have, and he handed them back in English. That was the semester my English grew the most.

Back in Korea I worked in English with colleagues abroad, and tried native-speaker phone lessons, AI conversation apps and chatbot voice chats. They all assume every word has to be English, so I kept falling back to the same easy small talk.

So Danny & Jenny gives you that friend:

• Phone calls with 20 Korean-American AI friends whose Korean ranges from beginner to fluent

• Keep the English going and drop in Korean where you're stuck; the friend recasts it into natural English inside the reply, with no lesson

• Friends remember earlier calls and call you first at the time you set

• After a call, retell the same story in English only; the phrases you actually said become spaced-repetition cards

Honest limits: iPhone only, the app is in Korean (it's built for Korean speakers learning English), and every friend is an AI. The app never hides that. Free: three 3-minute calls a week.

I'd love feedback, especially from anyone who has tried to speak a new language and got stuck mid-sentence.
