# Atesto > 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. 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. Atesto is built and operated by Akwatri LLC, a privacy-focused software > company. ## Plans & pricing Atesto is free to start. Paid plans are billed monthly or annually (about two months free), and can be changed or canceled any time. - Core (Free): your shareable card (QR code, link, or NFC tap), native contacts sync, and full account security (trusted devices, biometric lock, recovery codes). - Lens ($0.99/mo or $9.99/yr): choose exactly what each person can see, plus a searchable list of everyone who has your card. - Signal ($1.99/mo or $19.99/yr): verified badges on your phone and email, and contact groups with sharing presets. - Vault ($4.99/mo or $49.99/yr): multiple card profiles, shares that expire automatically, and a permanent public link people can save your card from without installing the app. ## Get the app - iOS: https://apps.apple.com/app/id6789431359 - Android: https://play.google.com/store/apps/details?id=com.akwatri.atesto ## Pages - [Home](https://atesto.akwatri.com/): what Atesto does, who it's for, and about Akwatri LLC. - [Help & FAQ](https://atesto.akwatri.com/help): common questions about sharing, visibility, contacts sync, plans, billing, and data handling.
