For people living with HIV and the people who love them. Five thoughtful introductions a day. One conversation at a time. Status framed by the science: Undetectable = Untransmittable.
The science is clear. People living with HIV on effective treatment cannot transmit the virus.
"When you and a match both say yes, a conversation opens — and stays single-file."
Other apps make HIV status a filter. We make it a fact — clear, respectful, ordinary — then get out of the way.
HIV status appears on every profile the way it should — with U=U context, current treatment, and last test date. Optional. Honest. Never weaponized.
No infinite feed. At dawn, you receive five people thoughtfully chosen for you — with a note explaining why. Read carefully. Choose slowly.
When you both say Interested, a chat opens — and it stays the only one until you decide otherwise. No juggling. No half-talks. The way real connection deepens.
448 isn't a niche. It's a community where status is one detail among many. Whether you're poz, neg-on-PrEP, or just done explaining yourself — there's a place here.
Every profile must include at least one face-verified photo. Verification runs locally on your phone via Google ML Kit. No biometric data leaves your device, ever.
448 carries a small, moderated community forum — for letters, questions, and support. Not a hot take. Not a comment war. Thoughtful company.
Three unhurried steps. An honest profile, a quiet drop at dawn, and one good conversation that goes somewhere real.
Pick the three qualities you're drawn to, the three dealbreakers you're not. Share your status the way you want it framed — including the option to lead with U=U. The more honest your profile, the better your matches.
Treated, undetectable since 2021. U=U explainer shown on my profile.
At sunrise, your day's introductions arrive — quietly, never as a notification storm. Each comes with a short note: what you have in common, where you might differ, and why we thought of you. Read. Choose Pass or Interested. That's it.
Our measure of success isn't time-on-app. When a conversation feels right, take it offline. Pick a coffee shop, log off, close the laptop. The best community space is the one you use once and then leave behind.
Decades of clinical research are unambiguous: when someone living with HIV is on effective treatment with a sustained undetectable viral load, the virus is sexually untransmittable. Undetectable equals Untransmittable. U=U. Every profile on 448 carries this fact, in plain language, where it belongs.
"Most online spaces treat HIV status like a content warning. We treat it like what it is — a piece of medical information, one of many things you might mention about yourself, easily understood by anyone who reads the science."
— Lauren Roberts, founder of 448
Before launch, here's what we're binding ourselves to. Hold us to it.
We will never filter discovery by HIV status. Your matches are people, full stop.
Every report is read by a real person within 24 hours. We will publish removal numbers when we have them.
Your HIV status is yours alone to share. We will never disclose it on your behalf — not to other members, not to advertisers, not to anyone.
We will never sell your data, share it with advertisers, or use it to train any general-purpose AI model. Health data least of all.
Privacy isn't a settings tab on 448 — it's the architecture. Here's what that means in practice.
Read the full FAQYou choose whether to share your HIV status on your profile, in chat, or never. We never share it for you.
Verification runs entirely on your phone. No biometric data is stored or transmitted. Profiles with a verified face photo get a quiet badge — no extra hoops.
Live in every chat. A real human reviews every report. Repeat offenders are removed for good.
Your profile, photos, messages, and matches can be wiped from our servers in a single tap. We don't keep "deleted" data around.
No. 448 is for poz people and the people who love them — allies, partners-to-be, and people on PrEP all welcome. What we ask is that you understand U=U before you swipe through anyone's status.
Only what you choose to share. You control whether status appears on your profile, in chat, or not at all. The U=U explainer is offered to every poz member, but never shown without your opt-in. It's your story.
When you and another member both say Interested, a conversation opens — and it's the only active conversation either of you has on 448 until one of you ends it. No juggling. No half-conversations. It's the constraint that makes everything else work.
Because five is plenty. Endless scroll trains you to skim; small, considered selections train you to read. We'd rather hand you five real people at dawn and let you give each one your attention.
A matching system that weighs your stated preferences (age range, distance, status preferences, the qualities you said you valued) against the same from members near you, plus a Safety pass that filters profiles that don't look right. Importantly: we don't filter on HIV status. Your matches are people, full stop.
Nothing exotic. Your data lives in Firebase with strict security rules, is encrypted in transit and at rest, and is never sold, shared with third parties, or used to train any general-purpose AI model. You can delete everything — profile, photos, conversations — from Settings in a single tap.
448 is a paid subscription — there is no free tier. We charge upfront so we are not pressured to monetize attention, advertise to you, or sell your data. You can pick monthly or yearly; both renew until you cancel. Restore and cancel from your Apple ID at any time.
iOS first, Android close behind. Follow along — we'll announce the launch day when it's locked in.
For too long, online spaces have treated HIV status as a filter — something to opt out of, hide, or apologize for. The science has long since moved on. Undetectable people on treatment cannot transmit the virus. Our community deserves a place where that fact is the starting point, not the punchline. 448 is that place: a calm, deliberate community for poz people and the people who love them — where meeting someone, talking openly, and supporting each other all happen on the same terms.
About the name: 4-4-8 spells H-I-V on a landline phone keypad. I chose the digits because, psychologically, the letters can sting. The numbers don't. The community knows what they mean — and the people who don't, we're happy to explain.
