WhatsApp – Free messaging, calls, and video chats
WhatsApp is one of the most widely used communication apps worldwide—and in the United States it has become part of everyday life for millions. We use it almost daily ourselves because it brings messages, calls, and content sharing together in one place. The best part: everything is free as long as you’re connected to the internet.
In practice, that means you can fire off quick messages to friends, share photos from a family gathering, or send documents to coworkers without worrying about SMS fees or expensive international calling. Many Americans rely on it when traveling or keeping in touch with friends and family abroad because it’s an easy, low-cost way to stay connected. WhatsApp works just as well in the U.S., Germany, or Thailand—the only thing you need is data or Wi‑Fi.
Features and capabilities in WhatsApp
✅ Free messaging and voice calls (domestic and international)
✅ Video calls with up to 32 people
✅ Sharing photos, videos, documents and location
✅ End-to-end encrypted communication
✅ Use WhatsApp on your phone, tablet, Windows and Mac
We tested the app on a Windows 11 PC and an iPhone. Installation was quick, but setup took a little extra time because you need to scan a QR code on your phone to connect WhatsApp Web/Desktop. After that, syncing worked flawlessly.
Design and user experience

WhatsApp’s design is intentionally simple, so even first-time users can find their way around quickly. On mobile it looks at first glance like a classic SMS app, which makes switching easy if you’re used to regular texting. The difference is that WhatsApp offers many more features—from group chats and photo sharing to voice messages and video calls.
On a computer, WhatsApp works like a convenient extension of your phone. If you send a lot of messages during the day, it’s a major advantage to use a keyboard and a larger screen. We found it especially useful at our desks when we needed to reply to many messages quickly—it almost feels like your phone is built into your PC. In the United States, where many people use both a phone and a computer throughout the workday, this combo is extra flexible.
Challenges and limitations
One of WhatsApp’s biggest limitations is that you can’t use it on a computer alone. The desktop version requires a phone to be connected and signed in. In practice, if your phone runs out of battery or loses its connection, WhatsApp won’t work on your PC either. That can feel a bit old-school compared to other chat apps where you just sign in directly.
We also found that larger video files can be a bit heavy to send, especially on a slower connection. A couple of times we had to wait longer than expected for videos to upload and send. It’s not a dealbreaker, but if you’re used to lightning-fast file transfers, it can feel a little slow.
