Antistalker

You are at a café, phone face-up on the table. A stranger walks by, glances down, and you instantly get a notification: “Unknown device detected. MAC address: XX:XX:XX:XX:XX:XX.” Your phone just identified a potential stalker before you even noticed them. This is not a scripted scene from a thriller — it’s a daily reality Antistalker is built to prevent.

Core Detection Tools

Antistalker transforms your Android device into a proactive personal security scanner. The app operates silently in the background, using your phone’s Wi-Fi hardware to continuously monitor for suspicious devices within Bluetooth and Wi-Fi range. When an unknown device — such as an AirTag, a Tile tracker, or a smartphone with a spoofed MAC address — enters your personal zone, the app triggers an immediate alert. The detection engine cross-references device signatures against a local database of known tracking hardware, flagging any model frequently used for non-consensual surveillance.

Key Functional Capabilities

• Real-time MAC address scanning – Continuously logs all visible Wi-Fi and Bluetooth devices within a 30-meter radius, updating the device list every 5 seconds for instant threat detection.
• Signal strength heat map – Visualizes the approximate physical distance and direction of each detected device, helping you locate a hidden tracker by moving toward the strongest signal node.
• Custom alert zones – Define up to 5 private safe zones (home, car, office) where only whitelisted devices are ignored; any unknown device entering these zones triggers a vibration + sound alarm.

Advanced Privacy Controls

The app does not require any personal account creation or cloud login. All device logs, scan histories, and whitelist entries are stored exclusively on your device’s encrypted local storage. You can export a full report of detected devices — including manufacturer, signal strength, and first-seen timestamp — as a PDF for law enforcement or personal records. A one-tap “stealth mode” hides the app icon from your app drawer and disables all notification previews, ensuring a stalker cannot detect that monitoring is active.

Why This Matters for Daily Security

Standard phone settings only show connected devices, not passive signals. Antistalker fills this gap by exposing every device that broadcasts a Wi-Fi or Bluetooth probe request near you — including those that never attempt to pair. The app works offline in airplane mode, scanning only for Bluetooth Low Energy (BLE) beacons, which is the protocol used by most commercial trackers. Battery impact is minimal: a full day of background scanning consumes approximately 6% of a typical 4000 mAh battery.
