Waon Online Tracker Last Seen is a utility application designed for Android users, focusing on monitoring online activity on WhatsApp. The app enables users to track the online status of specific contacts, providing notifications when those individuals become active. This feature is particularly beneficial for parents wanting to oversee their children's online presence or for anyone wishing to stay informed about their loved ones' activity.

In addition to tracking online status, Waon offers a Last Seen Tracker that displays when users were last active on WhatsApp. The application supports monitoring multiple contacts simultaneously, catering to both individual and business needs. Users can follow one contact for free, while real-time notifications ensure instant updates about online activity. However, it is important to note that the app cannot show the last seen status for users who have hidden this information on WhatsApp.
