It supports personal messages, calls, media and linked devices. Choose a business-oriented app only if you’re using WhatsApp for a business.
Which WhatsApp app should you install?
Install WhatsApp Messenger, the official app, rather than a modified or unofficial client. WhatsApp’s mobile download page directs iPhone users to the App Store and Android users to Google Play. The App Store listing names WhatsApp Messenger for iPhone and iPad, and also identifies availability for Mac and Apple Watch.

WhatsApp on iPhone and Android

Check your phone’s operating system before installing or updating. WhatsApp’s iOS support notice is a future-dated cutoff: from November 30, 2026, it says only iOS 15.5 and newer will be supported. The minimums and availability can change, so consult WhatsApp’s current platform pages if your device is near the cutoff.

WhatsApp Messenger or a business app?
For personal use, choose WhatsApp Messenger. A business-oriented WhatsApp client is worth considering when the account represents a business and its workflow calls for business tools. The current official material cited here is not sufficient to compare business features in detail, so choose based on the tools available in the app listing and official documentation for your region rather than assuming the business version is better for ordinary personal messaging.
Using WhatsApp on more than one device
WhatsApp supports linked devices, including selected tablets and desktop clients. Its download page describes linked-device options, and the Help Center’s linked devices guidance covers Mac and Windows calling. Mac and Windows apps support voice and video calls with up to 32 people. WhatsApp says each linked device connects independently while retaining end-to-end encryption.

WhatsApp says personal messages, photos and calls are protected with end-to-end encryption, meaning they stay between you and the people you choose and “not even WhatsApp can see them.” Its messaging page likewise says messages on any device are protected by end-to-end encryption.
