Apple’s AirTag item trackers launched with much fanfare at the company’s event in April. While the firm boasted about its privacy-focused features, severalreportspublished after the launch noted that there are many ways to stalk people using this device.

The most common method was to slip an AirTag into someone’s bag to track them. At that time, Apple had set AirTags to play a sound after three days of the tracker being separated from its owner. Now, the company is revising it to a random time between eight and 24 hours. So if someone has stealthily placed an AirTag in your bag, you’d be alerted sooner.

Apple is shipping this update to all AirTag devices starting today. To update your tracker, you’d just need to bring it near your iPhone.

Currently, you can detect a “lost” AirTag traveling with you only if you have an iPhone. To solve this problem, Apple has also promised to ship an Android app that could use its “Find My” network, and check if an unattended tracker is around them. The company told CNET that it’ll release this app later this year.

iOS devices can detect an AirTag that isn’t with its owner, and notify the user if an unknown AirTag is seen to be traveling with them from place to place over time.

However, it’s not clear if this app would break iOS exclusivity, and enable AirTags to be used as item trackers with Android devices.
