Dot: Network & Tracker Scanner

See the devices on your Wi-Fi and check for Bluetooth trackers that keep showing up near you.
All scans are free and need no account. Pro only removes ads.

Scan the Wi-Fi network you are connected to and review the devices found on it, including equipment discovered through LAN, UPnP and mDNS lookups. If something appears that you do not recognize, Dot shows you the details available so you can look into it further.

Monitor nearby Bluetooth and BLE activity, and review which devices show up repeatedly across different places and times. Recurrence is worth a closer look, although on its own it does not establish that a device is following you.

What Dot can help you review:

- Devices connected to your current Wi-Fi network, with the details available for each one
- Router and local network service exposure
- Nearby Bluetooth devices, and which of them recur across locations or days
- Magnetic field anomalies that may indicate concealed electronics nearby
- Reflective points and infrared light sources, using your camera as a manual inspection aid
- A practical guide to places worth checking, and sensible next steps when something seems unfamiliar

A note on what these results mean. Dot reports observations and risk indicators rather than conclusions. Radio conditions, iOS permissions, and the identifiers a device chooses to broadcast all affect what can be seen. A quiet scan does not prove that a space is clear, and an unfamiliar device is not by itself evidence of surveillance. The aim is to give you better information about your surroundings so you can make your own judgment.
