FAQs
Straight answers to the questions you’re too hydrated to ask out loud.
Yes. That’s the point. Models, runtime, and sounds ship inside the app. You can run it on a plane.
Beautiful liver.
Zero regrets.
Listen. LISTEN. It’s you. From 2029.
I’m GLOWING, bro. My liver? Pristine. My skin? Don’t even worry about it. People walk up to me — strangers — like “what is your SECRET?” I say water. They say “no for real though.” I say WATER. They walk away mad.
And you know why I look like this? Because an app told you to drink water and you DID it. That’s embarrassing. That’s also why I’m hot now.
Human is like fish.
Fish without water is dead fish.
So drink the water. Unlock the day. Be great.
