WhatsApp last seen status is a timestamp of the last date and time someone was active and online on the app. If you went offline by 3:00 am, then WhatsApp will display your last seen as 3:00 am, so your contacts can see when you were last online.
However, WhatsApp allows users to hide their last seen status for privacy and personal reasons. When someone hides their WhatsApp last seen, you won't see a timestamp showing when they were last online or even if they are currently online. This can make it challenging to know when to text someone or expect a reply.
So, how can you see someone’s hidden last seen status on WhatsApp? And is there a WhatsApp last online checker app?
This article aims to reveal the best WhatsApp online last-seeing checker app and show you how to check the last-seeing status of all contacts on WhatsApp.
