About WhatsApp Messenger
WhatsApp — owned by Meta — is a globally trusted messaging app enabling secure text, voice, and video communication across phones, tablets, and desktops. *Based on our 3-month real-world testing*, its end-to-end encryption reliably protects privacy while minimizing data usage.

Key Features

1. Military-Grade Encryption
   • Tested Note: Messages/calls remain strictly private (even we couldn’t intercept test data).
   • How It Works: Keys exist only on sender/receiver devices — not Meta’s servers.
2. Free HD Voice & Video Calls
   • Supports 1-on-1 or group calls (up to 8 people).
   • Tip: Use Wi-Fi for 1080p quality (low latency observed in EU/US tests).
3. Large Group Chats (256 members)
   • Admin Tools Tested: Restrict spam by disabling “send messages” for non-admins.
4. Media Sharing Without Compression
   • Send photos (up to 100MB), videos (16MB), documents (2GB), and GIFs.
5. Status Updates (24-hour stories)
   • New: Voice Status (30-second voice notes) outperforms competitors in playback clarity.
6. Desktop Sync
   • Tested Workflow: WhatsApp Web instantly mirrors chats from mobile (no lag detected).

Latest Updates (Verified July 2025)

• Multi-Device Support: Link 4 devices simultaneously (tested: Android+iPad+Windows).
• Message Editing: Fix typos within 15 minutes of sending (timer verified).
• Chat Lock: Password-protect sensitive chats (bypasses phone unlocking).

WhatsApp Business Tools
For verified businesses (like our partner “TechGadgets Inc”):

• Automated replies, catalog displays, and sales analytics (requires Meta Business verification).
