Xensr miniature motion tracker review

Shop For This Product

How small can you make a motion tracker? Apparently, smaller than an Oreo, as that’s what the Xensr is. Packing GPS tracking, an altimeter and a powerful ARM processor, the Xensr is designed to keep track of all your body’s motion, no matter what you’re doing.


The Xensr tracks your “Truemotion,” (trademarked, of course) at 400 times per second with 3mm precision and GPS location 100 times a second to within one metre. This allows the sensor to pick up data on jumps, tricks and spins while you’re surfing, bike riding or performing any other type of high flying stunt. This can give you accurate data on how to improve your movements, or simply show how versatile you are.

To make sure that the Xensr has as little impact on your movements as possible, it’s absolutely tiny, measuring just 44mm across and 14mm in height. As the official site points out, the Xensr itself is smaller than an Oreo.

It’s also water resistant to up to five atmospheres, so if you happen to drop it in a puddle you’re more than covered. We probably wouldn’t recommend going for a dive with it though. Fortunately it’s unlikely to fall off without you knowing, as you can mount the Xensr wherever you like due to its compatibility with many types of sport equipment.

In terms of the internal hardware behind all of the exciting features the Xensr offers, it packs a dedicated ARM CPU, up to four hours of data storage space and can send data to your smartphone using Bluetooth 4.0.


As it stands, you can’t order the Xensr directly as it’s still undergoing tests, but you can buy its predecessor, the XensrCase for iPhone 4/4S, which has some of the functionality of the final Xensr, for $150. However, when released, Xensr sensors will cost $250 for the standalone version, or $200 for the “lite”, smartphone accessory version.


While the Xensr is undeniably accurate, I’m wary about its ultimate uses. As an end user product I’m not sure its uses are that exciting, but in terms of engineering or product development, showing what certain products do in certain circumstances, it could be very useful. Likewise, helping sportsmen improve their game could be possible, but it’ll take some work.

Bottom Line

The Xensr is an interesting product, but it doesn’t do much more than what a lot of other wearables do, just more accurately. I think it has uses, but I’m not sure average consumers would derive much benefit from it.
