WhatsOnline is an app for monitoring selected WhatsApp contacts and reviewing patterns in your own WhatsApp activity. Its listing describes contact activity tracking, discreet monitoring options, and usage information intended to help you understand when contacts or your account are active.

Contact activity tracking

You can select contacts and view reported changes in their WhatsApp activity, including when they appear online, offline, or show a last-seen status. The listing presents this as a way to follow activity changes over time and identify suitable moments to start a conversation.

Discreet monitoring claims

According to the supplied description, WhatsOnline is designed to monitor contact activity without notifying the people being observed. The listing also claims that this can work when a contact hides their last-seen status or has blocked you, and says the app can monitor activity even when you do not have WhatsApp installed. These are source claims about the app’s behavior and are not independently verified here.

Personal usage patterns

The app also provides information about your own WhatsApp usage. Its described analysis includes how often you are online, when you are most active, and other activity data that can help you review your messaging habits.

App details

WhatsOnline is listed under the Lifestyle category and is identified as version 2.2. The supplied Android language field does not provide a usable minimum operating-system requirement, so compatibility cannot be specified from the available information.
