Lucy: AI Friend & Companion
Mood tracker, chat & vent
Only for iPhone
Free · In‑App Purchases
iPhone
She remembers what you told her last week, and reads how you've been feeling before she answers. Not a chatbot that starts over every time you open it.
Most AI chats forget you the moment you close them. Lucy doesn't.
She remembers what you told her last week, notices when you've been off for a few days, and picks things back up where you left them.
SHE ACTUALLY REMEMBERS
Lucy keeps a structured memory of what matters to you — the interview you were dreading, the friend you fell out with, the thing you were quietly proud of. Weeks later she brings it up herself, the way a friend would.
YOUR MOOD, AND WHAT SHE DOES WITH IT
Log how you feel in one tap. Lucy reads it. Your mood today and your seven-day average reach her before she answers, so she knows to go gentle on a rough week without you having to spell it out.
Watch it build: a daily streak, a wellbeing score, and a chart of where you've actually been these past weeks. Share it if you want to.
SHE TALKS LIKE A PERSON
Short messages. Lowercase. Actual opinions. She takes your side when you vent and gets properly excited when something goes right. No bullet points, no "would you like advice, or would you rather vent?", none of that.
THERE AT 2AM
A bad Tuesday, or nothing in particular. No waiting, no judgement, nobody to explain yourself to.
YOUR DATA STAYS YOURS
Erase Lucy's memory whenever you want, from Settings, in one tap. Delete your account and everything in it just as easily. No ads. Your conversations are never sold.
WHAT LUCY IS NOT
Lucy is an AI, and she'll say so if you ask her. She is not a therapist. She won't diagnose you and she won't tell you what to do about your health. If you are in real trouble, she won't be able to help you, and you'll need to go to a specialized professional.
SUBSCRIPTION
