WhatsApp, explained plainly

Roughly three billion people use WhatsApp, and almost none of them were given a manual. The app hides most of what it is doing: it shows you one tick without saying what a second tick would mean, it says “online” without saying what that proves, and it asks for your phone number without explaining that the number is the account.

Vobo answers the questions people actually type into a search box about it. Every article opens with a direct answer in the first two or three sentences, because that is usually all anybody wanted. The rest of the page is there if the short answer raises another question, which it often does — “can people see my phone number” turns into “then what can I actually hide?” within about ten seconds.

We are not affiliated with WhatsApp or Meta. That independence is the point: it means we can say plainly when a feature does not do what people assume, when a widely repeated claim is wrong, and when the honest answer is that nobody outside the company knows. There are several questions on this site where the truthful answer is “you cannot tell from the outside,” and we say so instead of inventing a test that does not work.
