Tonight, your English stops getting stuck.
Just speak. LUNA listens to your words, remembers them, and answers back. The more you talk, the closer you become.
— I remember every English word you've said to me.
Just talk
No buttons to think about. No sentences to plan. Just speak.
She remembers
Topics you shared, favorites, even your speaking habits — she keeps them all.
3 days, fully free
Try everything from day one. No surprises, no friction.
Inside the app
Not your typical English app.
Voice. Memory. A home on the moon. Everything LUNA does is built to keep you speaking.
Speak the moment it comes to mind.
Pick a topic, tap once, and start. LUNA waits patiently for your English to arrive.
- One tap to start a conversation
- Hints appear when you're stuck
- Even short sessions feel real
Pick up right where you left off.
What you said, what you love, what you struggle with — LUNA carries it all into the next conversation.
I won't forget.
- Conversations don't restart from zero
- Replies become uniquely yours
- The longer you stay, the more she knows
You and LUNA share a home on the moon.
Every conversation expands your place on the lunar map. Your days don't become a number — they become a place that grows.
- Your home moon shifts as you continue
- Continuing turns into a story
- Far more than a streak counter
