In the digital age, stalking has taken on a much more sophisticated—and terrifying—form. While breakups are supposed to mean distance and closure, some people refuse to let go. Increasingly, ex-partners are turning to hidden tracking devices to follow, monitor, or control the lives of their former partners without consent. These tools are cheap, small, and easily concealed, making them ideal for digital stalking and emotional abuse. If you suspect someone might be tracking you or someone you love, here are seven common tracking devices exes use—and how to detect them.
1. Apple AirTags and Other Bluetooth Trackers
AirTags, Tile, and other Bluetooth trackers were designed to help people locate lost items—but in the wrong hands, they’ve become tools for stalking. These quarter-sized devices can be slipped into a purse, car, backpack, or even clothing and go unnoticed for days.
To detect them, iPhones will now alert users if an unknown AirTag is “traveling with them.” For Android users, apps like Tracker Detect or AirGuard can scan for nearby devices. Always check bags, coat linings, and under car seats regularly if you feel someone is following your movements.
2. OBD-II Port Trackers Hidden in Cars
Many vehicles have an OBD-II port under the dashboard used for diagnostics—but stalkers can plug in GPS trackers here that monitor real-time location. These devices are powered by the car itself and can stay active for months without being noticed.
To find them, inspect the area beneath the steering wheel or consult a mechanic for a full diagnostic scan. If the device is found, remove it immediately and document it—this could become evidence in a restraining order or police report.
3. Magnetic GPS Devices Placed Under Vehicles
Small magnetic GPS trackers can be attached to the underside of a car, especially around the wheel wells, rear bumper, or gas tank area. These devices are popular among stalkers because they’re weather-resistant, battery-powered, and often undetectable unless you specifically look for them.
To check, use a flashlight and a mirror to inspect under the car. If you want to be thorough, visit a mechanic or law enforcement agency for a full scan. Some shops now offer electronic sweeps for hidden trackers, especially for domestic violence victims.
4. Smartphone Spyware and Hidden Apps
One of the most invasive tools used by controlling exes is smartphone spyware. These programs can be secretly installed on a phone and allow someone to see your messages, location, photos, and even listen to your calls. The scariest part? You may not even know it’s there.
Check for unusual battery drain, increased data usage, or unfamiliar apps running in the background. Factory resetting the phone and setting up a new password can help, but professional digital security services may be needed for serious cases. Always enable two-factor authentication on your accounts and keep your phone physically secure.
5. Fitness Trackers and Smartwatches
If your ex gifted you a smartwatch or fitness tracker, it could be doing more than counting steps. Many of these devices have built-in GPS and Bluetooth, which can be paired to their phone or app to monitor your location, even after a breakup.
If you’re using a tracker from your ex or one they had access to, reset it completely and remove any linked accounts. Better yet, replace it with a new device you purchase yourself to ensure full control over your data and privacy.
6. Hidden Cameras or Micro Audio Recorders
While not GPS trackers, hidden audio and video recorders are sometimes used in stalking scenarios, especially by ex-partners who had access to your home. These can be disguised as USB chargers, smoke detectors, picture frames, or alarm clocks.
If you suspect someone is spying on you in your home, check all new or out-of-place electronics. Use a RF (radio frequency) detector to scan for transmitting devices, or turn off the lights and use your phone’s flashlight to spot tiny camera lenses reflecting light.
7. Smart Home Devices and Shared Accounts
Exes who once had access to your smart home system—like doorbell cameras, Alexa devices, or smart thermostats—can continue monitoring you long after they’ve moved out. In some cases, they can even speak through devices to intimidate or manipulate.
Immediately change all Wi-Fi passwords and unlink any smart devices from shared accounts. Reset devices to factory settings and re-pair them with your personal email or phone number. If you’re unsure what’s connected, check your router’s admin page to see all active devices on your network.
Trust Your Gut—And Take Back Your Privacy
Stalking isn’t always loud or obvious. Sometimes it hides in the everyday tech we rely on. If something feels “off” in your daily life—if your ex always seems to know where you are or you feel watched—it may not be paranoia. It could be a hidden tracker. Don’t wait. Check your car, phone, and home. Talk to a trusted friend or call a local domestic violence resource center. And if you do find a device, document it and report it to the police.
