The Newton fitness monitor has been discontinued as of 2012. It has been replaced with an updated product, the Pebble, that has an activity indicator display on the unit itself, as well as uploading wirelessly to a computer. The Pebble can be worn either on your shoe or waistband. This addresses what I found lacking in the Newton. See the myInertia.com web site for current information.

2010 Review of the Newton:
The Newton was a shoe-clip accelerometer to track your steps and calculate distance and calories burned. It uploads wirelessly to your computer via a USB stick and connects to the myInertia.com website where you can view graphs and charts of steps, activity time, distance and calories burned. The upload is automatic and effortless. The drawback is that there is no display on the unit, you must go online to see your steps and other data. The company is geared towards workplace wellness.

Newton Shoe Pod

The Newton shoe pod is an accelerometer that detects your foot motion to record steps and speed. It translates this into walking steps and running steps. Even if you don't run, any quick motions get recorded as running steps.

Clip the Newton onto your shoe - through the shoelaces if it is a laced shoe or on the top of the shoe if it is a slip-on.

Size: The Newton is about the size of a half dollar coin.

Noise: It is silent.

Accuracy: I compared the Newton with the Fitbit pedometer, Omron pedometer, and GeoPalz pedometer. The Newton consistently recorded 10% fewer steps. This may be due to inaccurate positioning by me on my shoelaces, although 90% is considered to be accurate-enough for a pedometer. For accurate distance, there is a calibration tool on the myInertia.com web site.

Battery Life: The battery is not replaceable, you need to get a new Newton when the battery dies. When logged into the web site, you can see how much battery life you have left on the battery. It appears to me that it would last about 6-12 months with constant use.

Uploading Your Newton Data

Because the Newton has no display, you have to upload the data to a computer to see how many steps you have taken. The Newton purchase includes one year of access to the myInertia.com web site and the InertiaJump USB wireless stick. Replacements can be purchased separately.

To use the Newton, you need the InertiaJump USB wireless stick. If you have several people each using an Newton and uploading from one computer, you only need one stick.

On first use, you download and install the client software, and set a few basic bits of information about yourself. Weight is needed to calculate your calories burned. The set-up was easy.

System requirements: You must be running one of the following systems (or later): Windows XP, Windows Server 2003, Mac OS X.

Once set up, the upload is automatic any time you get within a few feet of the InertiaJump (assuming the computer is on and running and connected to the internet).

The Newton stores up to 12 days worth of data, so you should try to upload at least every 12 days.

The InertiaJump can also upload data from other myInertia devices, such as a scale and a blood pressure cuff.

myInertia.com Web Site

To get to the myInertia.com web site and view your data, you can click on the icon in your system tray, or use your browser.

On the Dashboard, you can see your steps, calories burned, active minutes and distance. I found it a bit disconcerting that it doesn't update automatically, that you have to click on "Refresh." It shows ongoing "odometer" totals, today's total, and personal bests.
Goals: You can set your daily target goal for each measurement: steps, calories, active minutes and distance. Your percent of achievement of this goal is shown.

The My Activity page has a chart shows walking, moving and running steps per each 15 minutes. Any time you have a constant activity for 15 minutes or more, it gives you a total of steps, time, calories and distance for that activity. It also shows you a graph, totals and averages over any chosen period of days.

There is no way to add in steps to make up for steps you did when you didn't wear the Newton monitor on your shoe, or fitness activities such as swimming that don't record steps.

Challenges: You can choose from a Challenge Catalog to join in a challenge such as averaging 4000 steps per day for four weeks. You can create challenges and join in challenges sent to you by other people.

Adventures: Select an adventure from the Adventure Catalog and begin logging your steps on a virtual journey. The current one I am on is to climb Mt. Everest via the South Col route by logging 27 hours of activity.

Comparison to Other Uploading Pedometers

Walking Workouts: The Newton doesn't give you the level of detail of your walking workouts that a more athletic-oriented pedometer would give. The web site doesn't allow you edit your step total to get credit for walks you took without the Newton or other fitness activities. The web site challenges and goals are geared towards beginner walkers.

No Nutrition Tracking Tools: The myInertia site doesn't allow for any nutrition/diet tracking.

Pedometer Size: The Newton is small and weighs almost nothing, but it is visible on your shoe.

Pedometer Accuracy: The pedometer is accurate for a continuous walk, although it may be harder to consistently position it on your shoelaces for the best accuracy.

Overall: I prefer an uploading pedometer such as the Omron HJ-720 ITC pedometer or the Fitbit pedometer. Both have displays you can read throughout the day as well as the capability to upload to a web site to view graphs and track your data. For those users who also use the myInertia scale and blood pressure reader, the Newton is a nice addition to encourage walking and movement.
