Getting Started Guide

Master Subtex in
minutes.

Subtex replaces the paper business card. You build one digital card, share it with a QR code, and everyone you meet lands in a searchable collection you actually keep. Here's everything you need to set up, swap cards, and work a room like a pro.

The 30-second version

One card. Every connection, remembered.

Subtex is a digital business card that lives on your phone. Instead of handing over paper you'll never see again, you show a QR code — the other person scans it, and both of your cards are exchanged at once. Everyone you meet lands in a searchable collection, so the conversation you had at a conference last spring is still one tap away.

What you'll need Subtex is free on both iPhone and Android. On iPhone you'll need iOS 18.6 or later. Grab it from the App Store or Google Play and you're ready to build your card.
Quick Start

The whole idea, in three steps.

This is the core loop, and it takes about three seconds in real life. Master this and you've mastered Subtex — everything else just makes it better.

01
Open the Share tab
Your QR code is already on screen — no menus, no setup. Just hold up your phone.
02
They tap "Scan QR Code"
The other person points their camera at your screen. That's the entire interaction.
03
Both cards swap at once
You feel a haptic tap and see a green checkmark. They get yours, you get theirs. Done.
1Create your account

Getting in takes one tap.

Open the app and create your login with whichever option you like:

If you sign up with email, just choose a password — at least 8 characters with one uppercase letter and one number. Already have an account? Pick "Sign In" instead, and "Forgot password?" will email you a reset if you ever need one.

2Build your card

Four steps to the card everyone scans.

First launch walks you through a short wizard. This becomes your default card — the one your QR code points at. Here's what each step asks for:

1. Welcome

Nothing to fill in — just tap "Continue" to begin.

2. "Basic Information"

Full name and Title are required. Company, phone, and location are optional — add what's useful, skip what isn't.

3. "Connect Your LinkedIn"

Optional, but worth it. The URL must start with https://www.linkedin.com/in/

4. "Profile Picture"

Tap "Choose Photo" and pick a headshot. Then tap "Complete" to finish.

A photo is required — have one ready You can't finish setup without a profile picture. The "Continue" button stays disabled on the last step until you pick one, and there's no skip. Line up a headshot before you start so nothing stalls you.

You'll also see a one-time prompt titled "Make Subtex Yours" asking about personalization. Answer however you like — it doesn't lock or unlock any features either way.

4Swap cards with someone

The three-second handshake.

  1. Open the Share tab — your QR code is already on screen.
  2. The other person taps "Scan QR Code" and points their camera at it.
  3. Done. Both cards are exchanged at once — they get yours, you get theirs.

You'll feel a haptic tap and see a green checkmark the moment it lands.

Meeting at an event?

A banner appears above your QR reading "Checking in at {event name}", and the connection is filed under that event automatically. If more than one of your events is live, you'll pick from a menu — Subtex won't guess. There's a "Not at an event" option too.

Not in the same room? Share a link

Tap the "Share" button next to the scanner to send a connect link through Messages, Mail, or anywhere else — perfect for people who aren't standing in front of you. They tap the link, confirm, and your cards are swapped. Links stay active for 7 days.

5Work your collection

Everyone you've met, never lost.

Every person you exchange with lives in the Cards tab. This is where a stack of forgotten business cards becomes a network you can actually use.

Shortcut: press and hold You don't even have to open a card to save it. Long-press any card in your collection and you'll get the option to add them straight to your phone contacts.

Notes & Tags Subtex One

Tap a card, then "Notes" to jot private reminders about how you met. "Tags" lets you label the relationship with a primary tag, plus any number of secondary tags.

Primary tags

👔 Colleague 💼 Client 💰 Investor 🤝 Collaborator 🎓 Advisor / Mentor 🧾 Partner / Vendor 😊 Friend ⭐ Other

Secondary tags (add as many as you like)

👑 Decision Maker 🎟️ Met at Event 🛒 Sales Opportunity

Tags follow the person everywhere. Tag someone once and it shows up on their event and team cards too — you'll see "Tags synced across all cards" confirm it.

Ask about a contact Subtex One

The sparkles button next to search opens AI search. Ask things like "How did I meet Art Vandelay?" and it answers from your own collection. You can also generate an "AI Summary" on the back of any card for quick context right before a meeting.

6Add people who aren't on Subtex

Capture the ones who don't have the app.

Met someone without Subtex? Go to Cards → + → "Personal Card". You'll need their name, email, and phone — all three are required. Company, title, and notes are optional.

It gets better if they join later If that person later joins Subtex, you'll get a banner — "{name} just joined Subtex!" — offering to link your offline card to their real profile. Accept, and your notes and tags carry over. Your history stays intact.
7Events

Turn a conference into a connected room.

To join an event: go to Events → + → "Join Event", then enter the code from your organizer. Some events also ask for a password.

Check your inbox When you're added to an event, you'll also receive an email invitation — a handy backup if you ever misplace the join code.

Inside an event you can tap "Check In to Event" (it flips to "Checked In"), read the "Event Brief" if the organizer wrote one, browse the "Attendees" list, and open the event playlist.

Meeting is what unlocks people Attendee profiles stay locked until you've actually scanned each other — you'll see "Scan their QR code to unlock this profile". Contact details, notes, and AI summaries stay hidden until then. That's deliberate: a real handshake is the key.

You can filter attendees by "All", "Connected Here", "Met Before", or "Never Met Before" to see exactly who's still worth meeting. There's no RSVP in Subtex — you join, and you check in.

Event cards are an enterprise feature Event cards, attendee profiles, and in-event scanning are available for enterprise events. At a standard event you'll see a panel reading "Event cards, attendee profiles, notes, and tags are available for enterprise events."
8Teams

How companies stay connected.

Teams are how a company or organization keeps its people connected. You can't create a team in the app — teams are set up by an admin in the Subtex dashboard. Until you're added, a new user sees "You'll see your teams here once an admin adds you to one."

If you have a code, Teams → + → "Join Team" gets you in. Inside, you'll find the team's events, the "Team Hub" brief, the member list, and a "Create Team Card" button for a team-specific version of your card.

Codes are issued by the organizer and can expire. Ask them to resend the current one.
