A WhatsApp online tracker continuously monitors a contact's availability and records every online period. InfiniteSpy watches each contact you add, logs when they come online and go offline, and builds a long-term view of when they are most often available.
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.
InfiniteSpy watches each contact's online status in the background and logs transitions as they happen, around the clock.
Every online session is stored with timestamps, so you can review weeks of availability history for any contact.
See which hours a contact tends to be online, so you can predict the best time to reach out.
Get notified the moment a tracked contact comes online, so you can respond while they are around.

The contact's physical location
Tracking refers to availability, never location.
InfiniteSpy never accesses messages, calls, photos, media, or location — only online availability.
InfiniteSpy tracks only availability — it never reads messages, calls, or media, and never reveals a contact's location. Use it for legitimate purposes such as monitoring your children's screen time or coordinating with family, and always in line with WhatsApp's terms and local privacy law.
Online tracking reflects a contact's WhatsApp availability, not what they're doing inside the app or who they are speaking with. If a contact's phone is offline or without internet, no transitions are recorded. Tracking depends on the contact's presence being visible on WhatsApp.
Start a free trial, add a contact, and see availability within minutes. Plans start at a few dollars per week and you can cancel anytime.
