The main purpose of "TrackR" is to locate a lost bunch of keys or a misplaced wallet. The "TrackR" sends a signal to the smartphone via Bluetooth and lets the person searching know where to look via a distance display and beep.

... or to track down the bike

Another function turns the "TrackR" into a potential bike finder if your bike falls into the clutches of thieves. Using the Crowd GPS function, you can find out from other users who have installed the same app whether the bike fitted with the "TrackR" was in your vicinity. If this is the case, the bike can be located on a map.

And does it work?

Location via Crowd only works reliably if there are numerous users of this product or with an installed app within range. It could therefore work better in urban areas - the manufacturer claims to have already sold hundreds of thousands of "TrackR" in Europe. However, if the stolen bike ends up out of reach of another "TrackR" user, then tracking it down is over - or at the latest when the battery is flat after around two to three months.
