WhatsApp: Free, end-to-end encrypted messaging and calls for billions

Human-built. AI-enhanced.

WhatsApp is a free, end-to-end encrypted messaging app that works across mobile, desktop and Wear OS, offering group chats, voice and video calls for up to 32 people, location sharing and 24-hour Status updates, with simple phone-number sign-up, though some users report a profile-picture visibility glitch and ask for an in-app browser.

WhatsApp is a messaging and calling application from Meta, used by more than 2 billion people in over 180 countries. It is free to download and use, with no subscription fees, and it runs on mobile devices and desktop, including on slow connections. Accounts are set up with a phone number rather than a username or separate login.

Features and functionality

Private messaging: Personal messages and calls are end-to-end encrypted. People outside the chat, and WhatsApp itself, cannot read or listen to them.
Voice and video calls: Supports voice and video calls with up to 32 participants, carried over the phone's internet service. Recent updates add the ability to transfer a group call between mobile and desktop, a waiting room for call links, and the option to pin a participant to a larger tile.
Group chats: End-to-end encrypted group conversations support messages, photos, videos and documents across mobile and desktop. Recent group history can be shared with new members when they are added.
Status updates: Text, photo, video and GIF posts disappear after 24 hours. Users can share them with all contacts or with selected ones.
Location and voice messages: Location can be shared with an individual or group chat and stopped at any time. Voice messages can be recorded and sent quickly within a chat.
Wear OS support: On a Wear OS watch, users can read and reply to messages and take calls. Tiles and complications provide access to chats and voice messages.

Usability and practical applications

The interface is simple, and the app suits everyday personal communication, family contact and community group chats. Desktop and web clients allow users to continue conversations away from their phones, and status posts and voice messages support brief updates.

Privacy and data handling

Data is encrypted in transit, and users can request that their data be deleted. Sign-up requires a phone number, and SMS verification is used in some regions to authenticate the number and secure transactions.

Considerations

Data charges may apply depending on the user's provider, and calls use the phone's internet connection.
Registration depends on a valid phone number, which is the basis for finding contacts who also use WhatsApp.

Pros

End-to-end encrypted personal messages, calls, and group chats, so content is unreadable to anyone outside the chat, including WhatsApp.
Free to use with no subscription fees, and free voice and video calls for up to 32 people.
Sign-up needs only a phone number, with no usernames or logins, and it shows which contacts already use WhatsApp.

Covers the basics well: group chats with photos, videos and documents, live location sharing, voice messages, and 24-hour Status updates.

Cons

Accounts are tied to a phone number, so your number is visible to contacts and, unless hidden, to other members of group chats.
The app may collect location and personal information, among other data types, which may concern privacy-focused users.
Some regions use SMS verification to confirm your phone number, and data charges may apply when using it on a cellular connection.
Links open in the device's default browser rather than an in-app browser, according to user feedback.
The app includes in-app purchases despite being free to download.
