Features and Performance
Both your connected phone and the TrackR will notify you with an alarm when they're out of range of one another. So if you leave your TrackR-attached keys behind, your phone will sound an alarm when you travel out of range, while the keys will sound off when you forget your phone. You can toggle these alerts on or off in the TrackR app's settings. You can also set custom alarm sounds from your phone's music library. I selected "Ain't No Mountain High Enough" as my alarm and it played the first few seconds of the song each time.
As for battery, the TrackR uses a standard CR1616 coin cell that must be replaced yearly. While it's nice that you don't have to worry about recharging the tiny device, there is no real way to tell when the battery is dying. That could be problematic if you happen to lose something right before the battery dies. On the flip side, at least you can replace the battery here, which can't be said of the Tile; once a Tile is dead, you need to buy a whole new one.
TrackR bravo is shipping now, priced at $29.99, though multi-packs will offer a cheaper per-device cost; it's available in steel, black, rose gold, and sky blue finishes. A waterproof rubber casing - suitable for pet collar use - comes in at $10 for a pack of three.
ou can manually search for your connected phone by pressing the button on the TrackR, while will cause it to sound an alarm when in range. You can do the same for the TrackR by tapping an icon in the app. These functions work whether or not the Separation Alert is enabled. They also work when your phone's volume is muted.
To test the TrackR, I asked my colleague to hide my apartment keys in the 5,000 square foot PC Lab. I wandered around, phone in hand with the TrackR app open. The keys were out of range at first, as indicated by the app's bisected main screen. The top half contains a Google Maps layout and a pinpoint that details where and when the TrackR was last seen. The bottom half has a green icon you can press to activate the TrackR's alarm, along with messages like Closeby, Far, or Near, which are a little too vague. I prefer the Tile
