SwitchBot’s Safety Alarm looks like a keychain flashlight and even has LEDs when you need some extra illumination and don’t want to reach for your smartphone. The device is available starting today for $39.99 in black, white, and aqua color options, but you can save 99 cents when buying a two-pack. Most of the time, it works as an NFC key for SwitchBot’s smart locks and can send “home arrival” notifications once you’re in Bluetooth range, letting family members know you’ve safely returned.

In an emergency, however, you can also remove the Safety Alarm’s short keychain with a yank, which triggers a few things. That LED becomes a flashing strobe light and is accompanied by a very loud 130dB audible alarm. When a connected phone is nearby, an alert is also automatically sent to up to five friends and family members that includes the last known location of the tracker when the alarm was activated, but not live-tracking.

If you’re not feeling safe but don’t feel the situation is urgent enough to activate the alarm, discreetly double-pressing a button on the Safety Alarm will trigger a “virtual phone call” that you can pretend to answer, which could act as a deterrent. It will ring even if your smartphone is in silent mode, the company says.

A variety of personal safety smartphone apps offer a fake phone call feature, and the SwitchBot Smart Alarm isn’t as compact or discreet as alternatives like Pebblebee’s Clip tracker, which recently added new personal safety features. But Switchbot’s will potentially provide more peace of mind with an alarm that’s over 30dB louder than the Pebblebee’s.

The Safety Alarm is IP65 water- and dust-resistant, so a heavy downpour won’t be an issue but it may not survive a complete dunking. It will run for about a year on a pair of user-replaceable CR2032 batteries or up to two years if not using the Apple Find My functionality.
