Why we built Last Seen Monitor

Last Seen Monitor is a WhatsApp online status tracker that sends you real-time notifications when your contacts come online. We built it because we were tired of opening WhatsApp over and over just to check if someone was available.

Whether you are coordinating with a colleague in another time zone, waiting for a client to be reachable, or simply wanting to catch a friend at the right moment, checking WhatsApp repeatedly wastes time and attention. Last Seen Monitor eliminates that by alerting you the moment a contact comes online — so you can focus on your work and reach out when the timing is right.

Security is at the core of what we do. The tool accesses only public online status information, protects your data with encryption, and never shares your activity or personal information with third parties.
