Radioactive is texting at the speed of thought. Every keystroke is live — no "is typing…" dots, no waiting for "send." When they pause, you feel it. When they backspace, you see it. When they're not online, you Zap them awake.
Each friend gets their own gradient. Their own pet. Their own corner of the app. Tap a card and you're already typing to them — no inbox, no thread list, just their face and yours.
Nothing waits. There's no "send" between thoughts. Every backspace, every pause, every "wait actually nvm" lands instantly. It's the closest thing to being in the same room.
Tap to send a buzz. Hold to charge a long one. Spam to send a burst. Their phone buzzes, screen flashes, and a fat "ZAP" shouts across their display. Use responsibly. (Or don't.)
Open the app and stuff just… falls in. Stickers, sparkles, weird little artifacts. They tilt with your phone, bounce off the edges, and you can pin the rare ones to your card. Move your cursor over the box — they know.
Your bubble is your signature. Crystal cyan. Hot rose. Deep plum. Sunset citrus. Each one renders as a real-time gradient your friend sees the second you start typing. They'll know it's you before they read a word.
Every word evaporates the moment you stop typing. No archive. No threads. No screenshots of your worst takes haunting you in 2031.
Radioactive is a 1-on-1 app. No groups, no broadcasts. Each friend is a private channel that exists only when you're both in it.
Zaps are real. Phones buzz, screens flash, vibrations stack. Important means visceral. Boring means quiet. We don't do notifications.
Radioactive is a small, weird, fast, beautiful chat app for the one or two people you actually want to hear from. It works on iOS, Android, and any pure-black screen you point at it.
No tracking. No ads. No "AI summarized your conversation."
