InfiniteSpy
Waiting to catch a friend abroad, a partner on night shifts, or family in another time zone? Get pinged the moment they appear on WhatsApp and start the conversation while they're around.
A WhatsApp online notifier pings you the exact moment a specific contact becomes reachable, so you can open the conversation while they are actually there. InfiniteSpy follows the people you are trying to reach and tells you the second their window opens.
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.
The instant the person you're waiting for appears on WhatsApp, you get a ping — so you can open the chat and talk while they're still around.
Days of watching turn into a picture of when each person reliably shows up, replacing lucky guesses with a rhythm for staying in touch.
An optional notification when they disappear tells you the moment passed, so you can decide whether to leave a message instead.
Keep several faraway contacts on a single list and see at a glance who is reachable for a call right now.
Everything runs in the browser on the device you already use — no extra app competing for your attention.
Three steps from adding a number to reviewing availability — no app to install and no access to anyone's phone.
Add the WhatsApp numbers of the people you keep missing — a friend overseas, family abroad, a night-shift partner.
Reachability is checked continuously around the clock and across time zones, so you never set alarms to try your luck.
Your ping arrives the instant someone appears. Open WhatsApp and say hi while the window is open.
InfiniteSpy is transparent about exactly which information it reports. Availability only — never private conversations.

Being online says nothing about location.
InfiniteSpy never accesses messages, calls, photos, media, or location — only online availability.
Staying close across distance shouldn't require surveillance. InfiniteSpy signals reachability and nothing else — never message content, calls, or whereabouts — so use it to reach the people in your life at a good moment, respectfully, and within WhatsApp's terms and local privacy rules.
A notifier can tell you someone opened WhatsApp, not that they have the time or headspace for a conversation. People in low-signal areas show as offline even when they'd love to hear from you, and pings depend on your own device letting notifications through.
