Moov Now is a tiny movement sensor that is primarily designed as an activity tracker. However, this review will focus on its capabilities as a [[Running Sensors| Running Sensor]], though will also cover some of its other functionality. For runners Moov Now is capable of measuring [[Cadence]], Range Of Motion and Tibial Impact. Cadence is probably the most critical of all metrics to capture for runners, and thankfully it's a fairly easy to measure and so it's become quite pervasive. While the Range Of Motion is slightly intriguing, it's unclear to me how to interpret the value. The most interesting aspect of Moov Now is its ability to measure Tibial Impact.
* Note: currently Moov Now display an incorrect value for the average impact score for a run. The real time display during the run appears close (based on validation with [[TgForce]]), but the average is vastly higher. I have an open bug report with Moov.

=Tibial Impact =
The most interesting metric that Moov Now provides is impact, and because the sensor is worn around the ankle it is measuring the impact on your lower leg (tibia). The impact measured on your lower leg will be the impact that is felt at your knees and to a lesser extent the rest of your body. [[Running Sensors]] such as [[RunScribe]] and [[MilestonePod]] measure the impact of your foot, and your foot and ankle are capable of absorbing significant force. I believe that the measurement of impact at the lower leg is a far more useful and important metric, though I should stress that I do not have the science to back this up. I have observed that the discomfort from my torn meniscus seems proportional to the impact on my lower leg, not the impact on my feet. If I move to a forefoot [[Foot Strike]] the impact measured on my feet tends to go up while the impact on my lower leg goes down along with any knee discomfort. The only other [[Running Sensors|| Running Sensor]] that measures [[Tibial Impact| Impact]] is the [[TgForce]], and I'm working to compare the two. My initial thoughts are that the Moov Now is vastly cheaper, and it's a far more polished, consumer ready device. Moov Now is also capable of functioning as a lot more than just a sensor for Tibial Impact, and more than just a running sensor. On the flip side, while TgForce is an expensive "one trick pony", it performs this one trick really well. My initial testing indicates that Moov Now has some implementation bugs. The Tibial Impact shown in real time on the display does not relate to the average impact shown on the summary (I have a support ticket open with Moov.)
=Activity Tracker=
My primary interest in Moov Now is as a [[Running Sensors|| Running Sensor]], but I have included some notes here about its use as an activity tracker. While there are some things I rather like about Moov Now overall I'm rather uninspired.
