If you’re struggling to find a Mother’s Day gift under $30, location trackers are a good investment, helping mom keep tabs on keys, bags, luggage, and other valuables. The latest Tile Pro is one of the best on the market, and it’s on sale for $24.99 ($10 off) at Amazon and directly from Tile. While this isn’t a new deal, it’s still its best price of the year and only $2 shy of its all-time low, which is why it’s worth highlighting ahead of the holiday.

A big part of why I like the Tile Pro is that it works equally well with both iPhones and Android devices. Compared to other trackers that depend on Google’s Find Hub network, it’s more reliable when trying to track down lost items away from home, which is why it’s our go-to pick for Android users. Apple’s new AirTag still offers more precise location tracking overall for iPhone owners, but the Tile Pro has a few advantages of its own.

For one, it includes a keyring hole, so mom can attach it to keys or luggage without buying extra accessories. It’s also Tile’s most capable tracker, offering a Bluetooth range of up to 500 feet and Tile’s loudest ring at 110 decibels, which I’ve found is slightly louder than Apple’s latest AirTag. That comes in handy when trying to track down a misplaced phone, since the Tile Pro can make the phone ring even when it’s set to silent.

Plus, it’s the only Tile with a replaceable CR2032 battery, so mom won’t need to replace the tracker itself once the battery dies after about a year. Tile also includes a handful of free safety and convenience features AirTags lack, including two days of location history and crash detection, which can alert emergency contacts if the app detects a car accident. A paid subscription, which starts at $7.99 a month after a free one-week trial, adds extras like SOS alerts that connect to a live emergency dispatcher, local crime reports, and up to $100 in stolen phone protection.
