How to check if an AirTag or tracker is following you

Bluetooth item trackers are brilliant for finding lost keys and lost luggage. They're also cheap, tiny and easy to slip into someone else's bag or car. That's why Apple and Google both build unwanted tracking alerts into their phones, and why it's worth five minutes to make sure yours are actually switched on. Apple's alerts now cover AirTags, AirPods, Find My accessories and compatible trackers from other brands, and its list includes the AirPods Pro 3 charging case.
