App Description
Your contact info is outdated before you hit send. New job? New city? Traveling with a temp SIM? You're stuck messaging everyone individually—again.
Teth3r fixes this forever.
Create one living contact card. Share it once. When you update your phone, email, or address, everyone who has your card sees the change instantly. No re-sharing. No "hey, my new number is..." texts. Just automatic sync.
THE PROBLEM WE SOLVE
Traditional contact sharing is broken. vCards become stale the moment you send them. NameDrop is one-and-done. LinkedIn doesn't have your personal number. Every life change means repeating yourself to dozens of people.
Teth3r keeps everyone synchronized automatically.
HOW IT WORKS
1. Create your card with phone, email, address, and socials
2. Share via link, QR code, or the iOS share sheet
3. Recipients view your card instantly at teth3r.me - no app required
4. Update your info anytime. Everyone sees changes immediately.

- Beautiful Web Cards
Your card lives at teth3r.me/yourname. Anyone can view it, tap to call, tap to email, or save to contacts - without downloading anything.
- Smart Permission Tiers
Control exactly who sees what. Share your work email with colleagues, home address with family, and personal number with close friends. Different info for different people.
