WhatsApp remains free, end-to-end encrypted messaging and calling with no subscription, but it demands a phone number up front and offers nothing for people who want a handle instead.
4.1 / 5
WhatsApp is a messaging and calling app owned by Meta that works over the internet instead of your carrier's texting plan. You sign in with a phone number, no separate username or password to remember, and it finds which of your existing contacts already use it.
The core of it is one-to-one and group chat with photos, video, documents and voice notes, plus voice and video calls that the developer says support up to 32 people at once. It also has Status, a feature for posting text, photos or short clips that disappear after a day, shareable with everyone or a chosen subset of contacts.
The headline feature is encryption: the developer states that messages and calls are end-to-end encrypted, meaning not even WhatsApp can read or listen to them. That's a real technical claim worth taking seriously for anyone who cares about message privacy, though it's the company's own description and not something outside testing here confirms.
The bigger practical decision is the phone number requirement. There's no way to sign up with just a username, and the listing notes that some regions rely on SMS verification to confirm your number. If you want a messaging identity that isn't tied to your SIM, this isn't built for that. Desktop support is included, which matters if you regularly switch between typing on a keyboard and a phone screen, and the whole thing is free with the developer explicitly ruling out subscription fees, though data charges from your carrier still apply.
The listing is thin on anything past chat, calls and Status. There's no mention of chat backup, storage caps for media, or what a user does if they change phone numbers, all fairly basic concerns for an app people use as their daily communication line. Status content disappearing after 24 hours is fine for the format it's copying, but there's no option described for keeping a permanent record of what you post.
None of this changes the fact that WhatsApp does the two things people actually install a messaging app for: reliable group chat and free calling, both encrypted, both cross-platform. Compared with something like Google Messages, which leans on RCS and SMS integration, or Messenger, which is tied to a Facebook identity, WhatsApp's pitch is a phone number, a group of contacts already using it, and not much else to configure. That simplicity is the whole appeal, and also the extent of what the listing tells you about it.

OpenAI's official app packs text, voice, image generation and photo understanding into one free client, but the deepest features and the fastest models still sit behind a subscription.
