A WhatsApp activity tracker records how long a contact stays online and when those sessions happen. InfiniteSpy logs every online session, measures its duration, and turns the data into daily and weekly patterns so you can see how a contact's availability shifts over time.
InfiniteSpy is a browser-based WhatsApp availability tool. It shows when contacts come online and go offline, with real-time alerts and activity insights — and never reads messages, calls, or media. Start a free trial →
Each feature reports availability information only — never message content, calls, or media.

App usage inside WhatsApp
Activity means availability, not in-app actions.
InfiniteSpy never accesses messages, calls, photos, media, or location — only online availability.
InfiniteSpy's activity tracking measures only online availability — never message content, call logs, or media. It's well suited to monitoring children's screen time or understanding family availability, and should always be used in line with WhatsApp's terms and local privacy law.
Activity tracking reflects when WhatsApp shows a contact as online; it doesn't show what they're doing inside the app or who they're speaking with. If a contact is offline for long periods, no activity is recorded then, and totals only cover time actually observed online.
