What Atesto does
Atesto is a contact-sharing app for iOS and Android. Instead of asking everyone you know to keep your saved number or email up to date, you maintain one living contact card — and the people you've shared it with see your changes automatically.
One card, always current
Update your phone number, email, or address once. Everyone you've shared your card with sees the change — no group text, no "hey, I got a new number" round-robin.
You decide who sees what
Sharing is explicit and one-directional. You choose exactly who receives your card, and you can adjust or revoke what they see at any time. No one but you can edit it.
Share it with a scan, not a spreadsheet
Hand off your card with a QR code, NFC tap, or link instead of typing your number into someone else's phone. Handy for small business owners and professionals who share their info often — it's the same living card, so it never goes stale.
Who it's for
Atesto is built for anyone tired of stale contact info:
- People who change phone numbers or email addresses and don't want to chase down everyone who needs the new one.
- People who've missed a call, text, or invite because someone had outdated contact info for them.
- Professionals who hand out their contact info often and want it to stay accurate without manual upkeep.
- Anyone who wants a single source of truth for their own contact details, instead of whatever each contact's phone happens to have saved.
Plans & pricing
Atesto is free to start. Every plan includes your shareable card (QR code, link, or NFC tap), native contacts sync, and the full account security stack. Paid plans are billed monthly or annually (about two months free), and can be changed or canceled any time.
