Noom Walk, a pedometer app for android, does a “Moon walk” against the competitors


Noom walk, is a pedometer app for android. Yes it does a “moon walk”, against the competitors by not using the GPS to monitor and log your walk or steps made. It instead makes a good use of the “low-battery-drain” sensors, this translates to less battery usage that is about 2% of the total battery usage in a day. Along with that, some smart algorithms are used to track your movements such as steps all day long and as long as your phone is on.

I know the moon walk, doesn’t make any sense, but the word Noom when read backwards reads, Moon. That inspired me to use it. Also the tagline of the App is “The simple pedometer that inspires steps”. Ok forget the silly word play, let’s go over the app.


As soon as you install the app on your android phone, the first button to tap is start, It then starts counting all the steps you make with the phone, 24×7 non stop.

It then at the end of the day displays the total steps you made for that day.

It has the social integration with Google plus and Facebook. Once linked and went social, your family or friends can high-five you or add a note on your steps.

This could be motivational to see how the people you care, does well with the pedometer.

The profile is public, anyone can take a look at your profile. This is one of the concerns people have. You can turn on the private mode, and your profile becomes invisible to others.

As well as, the steps count figure, is just the total step count made for that day. People want to see that in a better understandable numbers like miles. To convert your steps made for that day into miles,

Converting steps to miles.

Converting steps to miles, the simpler way is to walk over the known distant path.

If you know the path you are about to walk is about 500 feet, there are 5280 feet in a mile. So your path’s distance is about 0.09469 mile. Would you walk about 0.09469 miles? No, this is inaccurate, as it doesn’t take in your stride length. A stride length is the distance, one of your leg moves to take a step. Left to right is one stride, right to left is another stride. A stride length is about 40% of your height, 42% to be precise.

If you are about 5’8″ tall (5.7 feet), your stride length is 42% of 5.7 feet, which is, 2.4 feet.

So, the final miles walked would be = (stride length in ft. x Total steps)/5280.

A 500 feet walk, or (500/2.4), 208 steps, in miles would be = (2.4 x 208)/5280, equals to, 0.09454 miles. Just by taking the rounded figure of 0.095, both calculations, taking in the stride length or not, are equal. But it differs in tiny fractions, this is OK for a small distance, but it adds up when you walk over a mile.


So, lets assume, the profile above, Betsy is about 5’8″, her stride length would be 2.4 feet. Her total steps taken is 12,335. So the miles she walked would be, (2.4 x 12,335)/5280, which equals to, 5.6 miles!

Adjusting the stride length, when you run as well.

When you are running and walking, the stride length varies from just the walking stride length. To know your average stride length, just divide the known distance by steps made.


This free app from Noom, inc makes a good pedometer without draining your battery. This is the current popular non-GPS pedometer for android. There are other similar apps as well, that doesn’t make use of the GPS, but those seems to fail to work well on most of the android devices. Noom Walk is the first non-GPS pedometer that clearly states how they are making the pedometer work without GPS. It is a featured app on Google play this week. But one thing that needs a bit more explanation is, on the low-battery-drain sensors and the algorithms. But I guess it’s their secret sauce. Well, the app performs well, and more and more installs will say how much better this app is.
