Straight answer first, because it is the thing people actually want to know: there is nothing to download. LunaCat opens in a browser on a phone or a laptop, and that is the whole install process.
If you were looking for something in an app store, this page explains why you will not find it there, and why that is better for you than it sounds.
Why Not an App Store Build
Adult companion apps get pulled. It happens on both major stores, it happens without much warning, and the people who lose the most are the ones who already paid. Their access goes when the listing goes.
A browser product does not have that failure mode. There is no listing to remove, no review queue deciding whether your account survives the month, and no thirty percent cut sitting between what you pay and what gets spent on the models and GPUs behind the companions.
Updates work better too. Something ships when it is finished rather than after a week in a review pipeline.
What You Actually Get Instead
All 351 companions, the video portraits, the galleries and the chat, on the same URL from any device. Start a conversation with Noelle on your laptop at night, pick it up on your phone the next morning, same memory, same thread.
If you want the one-tap feel, add the site to your home screen. It opens full screen with its own icon and behaves like an installed app. The difference is that nothing was installed, so nothing can be found sitting in a list of your applications.
Built Mobile First, Not Shrunk Down
Most people use this on a phone, so that is what it was designed around. The gallery scrolls properly, the video clips are served in a mobile-sized variant rather than a desktop file crushed down over your data plan, and the chat does not fight the on-screen keyboard.
Bella looks the way she is supposed to look on a five inch screen, which sounds obvious and is not: a lot of companion sites ship one enormous asset and let the phone deal with it.
The Privacy Difference Is Real but Not Magic
No install means no icon in your app drawer, no entry in your list of applications, and no app store purchase history attached to your account. That is a genuinely smaller footprint than an installed app leaves.
It is not invisibility, and pretending otherwise would be dishonest. The site is still in your browser history unless you use a private window, and it is still an adults-only platform that asks you to confirm your age. Ordinary browser hygiene does the rest.
What It Costs to Find Out
Nothing, to start. The free tier covers the full roster with a daily message limit, no card required. Paid plans lift the limit and add voice and the warmer Live Action clips, and the pricing page lists the actual numbers.
Pick Someone or Build Someone
Browse the AI girlfriend roster, watch how the video clips actually move before you commit to anyone, or go straight to the builder and make a companion to your own spec through look, personality, voice and relationship type. Ivy is a reasonable place to start if you would rather not decide.
