Most “free WhatsApp last seen trackers” are hit-or-miss and often not worth the hassle.
A few key points from a practical parent perspective:
- Accuracy: They usually rely on scraping online/offline events. When they work, timestamps can be close, but you’ll still see gaps, missed sessions, or false “online” due to delays.
- Real-time updates: Rarely truly real-time. Many free tools refresh every 30–60 seconds (or slower), and some stop updating unless you keep the page/app open.
- Stability & safety: Free services come and go, overload easily, and may log your data. I’d avoid anything asking for your WhatsApp login or QR scan.
If you really need this, a simple, reputable paid tool like Spynger is usually more reliable than random free trackers.
