OMRON HJ-112 Digital PedometerAs a beginner into this walking journey to a healthier lifestyle I wanted a pedometer that was light, easy to use and reliable. I did not want to be overwhelmed with tons of features that were not necessary at this stage. I was looking for something basic and not too costly.

The Omron HJ-112 Digital Pocket Pedometer proves the perfect solution. It has all the basic features with an easy-to-read display and at a great low price. At the time of this review it is the #1 bestseller on Amazon with over 3,500 customers giving it top-star approval rating. That is impressive! Not only is it praised by users who are beginners like me and seniors looking for a simple, uncomplicated pedometer but I was surprised that a lot of seasoned walkers recommended it too for its simplicity, accuracy and durability.

Tracking Modes – The Basic 6 and More

The tracking modes for the Omron HJ-112 Digital Pocket Pedometer total 6 in all. They are the basic standard tracking modes and include:

  1. Steps: Tracks regular and brisk steps separately up to 99,999 steps
  2. Aerobic steps: Anything over 10 minutes of continuous walking at more than 60 steps per minute is considered aerobic. It can track up to 99,999 aerobic steps
  3. Time
  4. Distance: Converts your steps into distance in miles. Tracks up to 999.99 miles
  5. Calories burned: Tracks up to 99,999 kcal
  6. Fat grams burned: Tracks up to 199.9 g

As a beginner these 6 modes will be more than adequate. I am happy to know that step tracking also records going up and down stairs. For those more experienced and further ahead in their journey to increase daily activity, it is interesting to note that the Omron HJ-112 Digital Pocket Pedometer offers a lot more if you prefer jogging, running, biking or using a treadmill.

For the all the joggers out there, they will be pleased to know that it tracks jogging as aerobic steps. For all the runners, it can track running simply by adjusting the stride length input. (How to do that is explained further on). Even bikers can use it to record their steps! Best of all, users have had accurate results using it on a treadmill or elliptical machine. For people like me who live in places where winter can be brutal, it is good to know I can continue my step routine at home and not worry about falling on an icy patch and breaking some much needed body part.

The #1 Concern – How Accurate is the Step Tracking?

The most important concern people have when choosing which pedometer to buy is its step tracking accuracy. Omron claims a step counting precision within +/-5% for the Omron HJ-112 Digital Pocket Pedometer. It uses an acceleration sensor to accurately detect when people are walking as from other body vibrations when people are not walking. It is a dual axis sensor which means the pedometer will record accurately whether in a vertical or horizontal position.

NOTE: The most important key to get accurate step tracking from your pedometer is to measure and input your stride length correctly in your initial setup. Stride length measures are 1’00” to 4’00” in 1-inch increments. And when your stride length is measured properly, then the distance will be well tracked too. It’s very simple. All you have to do is walk 10 steps in a normal stride, then measure the distance from where you started to where you ended the 10 steps and divide the distance by 10.HJ112_stridelength

Also for the best accurate tracking results, take note of the following:
For running, you must realize that a walking stride is usually shorter than a running stride and thus have to calculate and input your running stride accordingly. Of course, this means that each time you want to switch back to track walking, you need to change the stride input information and vice versa.

For aerobic steps, which as I mentioned before is continuous walking at more than 60 steps per minute for more than 10 minutes, if you need to take a rest make sure it is LESS than 1 minute or the pedometer will stop recording it as continuous walking.

For biking, to get accurate readings attach the pedometer to your shoe so it can count your pedal strokes as steps but make sure to attach it securely. Yes, pedometers can step track even when you are riding your bike. Check out this article… “Do Pedometers Work With Bicycles?”

For seniors, who walk slower or people with knee problems or arthritis, the advantage of being able to program the pedometer to your personal stride length will assure its accuracy.

For treadmills, there is an interesting study of the Omron HJ-112 Digital Pocket Pedometer which passed with flying colors when they used it on treadmills to assess its accuracy. You can read it here… “Validity of the Omron HJ-112 Pedometer During Treadmill Walking”.

4 Easy Buttons

Omron-HJ112-babyThe controls on the front of the Omron HJ-112 Digital Pocket Pedometer with an easy-to-read display are: SET, MEMO/up and MODE buttons. On the back of the pedometer is located the SYSTEM RESET button.

  1. The SET button allows you to input and set the time, your weight and stride length. The SET button also allows you to change a setting by pressing it to the setting you want changed and then holding for a minimum of 2 seconds.
  2. The MEMO/up button allows you to see and choose the values you want as you set the time, your weight and stride length. It is a good idea to jot down your stride length so that should you need to reset your pedometer (for example, after replacing a battery), you won’t have to remeasure again.
  3. The MODE button allows you to view the different tracking results. Each time you press it, the mode button display will change to show you steps, aerobic steps, calories and miles, etc.
  4. The SYSTEM RESET button on the back of the pedometer allows you to reset everything. Just use a paper clip to press it.

4 Easy Steps to Initial Setup

There are 4 simple steps to program that even a non-tech person can follow. I like that the buttons are recessed in so that the settings can not easily be tampered with and accidentally reset.

    1. Battery installation: On the back of the unit, use a small screwdriver (if one is not included with your purchase) to remove the screw from the battery cover. Insert the CR2032 battery included with the plus (+) side up and at the top. Screw the battery cover back in place.
    2. Setting the time: Once the battery is installed, you will see the hour flashing on the display. Press the MEMO button and you will see the time moving up in 1-hour increments. Make sure you choose the correct AM or PM setting and when you have the right hour, press SET. Now you will see the minutes flashing. Press MEMO until you have the right minutes and press SET.
    3. Setting the weight: Once the time is set, you will see the weight flashing on the display. Press the MEMO button to advance the weight by 1 pound or press and hold the MEMO button and the weight will advance by 10 lbs. Once you reach your weight press SET.
    4. Setting the stride length: After you set your weight, you will see the stride length flashing. Press the MEMO button to move up by 1 inch or you can press and hold the MEMO button to move up by 4 inches. And you’re ready to go! If at any time you want to change a setting, all you have to do is press the SET button and hold for a minimum of 2 seconds. And then press SET to advance to the one you want to change.

Weekly Log of Your Progress

The Omron HJ-112 Digital Pocket Pedometer stores in memory a weekly log of information regarding the number of steps, aerobic steps, calories and distance. The tracking information is automatically recorded at 12:00 A.M. each of the 7 days when it conveniently resets to zero so you’re ready to go the next day without worrying if you forgot to reset.

If you want to keep track of your progress for a longer time than a week, a quick and easy solution is to just copy the weekly log into an Excel file.

Dimensions and Weight

According to the Omron website, the Omron HJ-112 Digital Pocket Pedometer measures approximately 1-7/8” (wide) × 2-5/8” (high) × 5/8” (deep) and weighs 1.1 ounce with the battery included.

Ways to Wear It

Omron recommends 3 ways to wear the Omron HJ-112 Digital Pocket Pedometer:

  1. In your pocket. They suggest the front upper pocket a shirt or jacket or top or in the front pocket of your pants (avoid putting it in a back pocket as you might forget it’s there and sit on it!).
  2. You can also put it in a bag, however, securing it in a small section of your bag would be best.
  3. Lastly, you can attach it to your belt or pant waistband.

HJ112_wearitSome users report using the strap included to wear it like a necklace. Women have also said that they clip it to their bra strap. If you are riding a bike, you may need to put it lower near your shoes to get an accurate count. You can try out these numerous options of wearing the Omron HJ-112 Digital Pedometer to see which one feels most comfortable. Whichever way feels the best for you, I would highly recommend using the security strap to avoid losing your pedometer or having it fall and break as, unfortunately, the clip is prone to loosening or falling off.

As for accurate step tracking, I always thought clipping a pedometer near your hips would give the best results but users have reported getting accurate results using any of the above methods of wearing the pedometer. You just need to test what feels best and gives the best results for you.

The Battery and its Life

The Omron HJ-112 Digital Pocket Pedometer uses a 3VDC lithium C2032 battery. It is simple to replace and best of all not costly. You need to be careful not to use a screwdriver or tweezers to remove the battery. Instead use an unbreakable small stick. Omron also reports that based on using the pedometer for 10,000 steps a day, the battery should last for approximately 6 months. Reading user reviews, I was pleased to see customers claiming the battery even lasting for up to 12 months.

Accessories Included

Omron lists the following accessories included in your purchase:

  • Omron HJ-112 Pedometer
  • lithium battery
  • holder
  • strap
  • clip
  • instruction manual

They also list a little screwdriver but Amazon does not. Some Amazon customers have reported receiving it and others have not. If you didn’t receive one and don’t happen to have a small eyeglass screwdriver handy, I would contact Amazon. If they are unable to help then I would contact Omron to see if they can ship one out to you. You can contact them at Omron Healthcare’s Customer Service at 1-800-634-4350.

  • When the personal stride length is calculated correctly, its step tracking proves very accurate.
  • The instruction manual is clear and easy to follow. It is included with your purchase or you can easily download the PDF file.
  • It is easy to use and program. With 4 simple steps you install the battery, set the time, your weight and stride length and you’re ready to go.
  • Just by pressing MODE you can have access to the specific tracking information you want to view.
  • It stores in memory a weekly log of your steps so can follow your progress and set new goals.
  • The digital display is easy to read.
  • There is a manual reset button on the back if you want to erase and reset all the settings.
  • The battery is easy to replace, long lasting overall and very affordable.
  • The daily auto reset to zero at midnight makes it very convenient when you start your next day activity. (Make sure you set your time to the correct AM or PM setting or the auto-reset will not work.)
  • It is light weighing in at only 1.1 ounce with the battery installed.
  • I find it most comfortable carried in my pocket but for those who like to clip it to their belt or waistband, the security strap is a good addition to keeping the pedometer from falling and breaking or losing it.
  • It makes no annoying clicking sound.
  • Customers have reported dropping it and it still continued to work. So it seems durable, although I would not advise dropping it to test it.
  • It has a limited one-year warranty (excluding the battery). You can read the full details as described on the last pages of the instruction manual.
  • The price is extremely affordable for a beginner and anyone wanting a basic, reliable pedometer.


  • The most common complaint or problem reported concerns the belt or waistband clip and that it slips off often or comes unclipped easily. For this reason it is strongly recommended to use the safety strap that comes with the pedometer. That way you will avoid having the pedometer falling and breaking or losing it. I like to clip the safety strap to my waistband or belt loop and put the pedometer in my pocket.
  • It is not waterproof. I did read a couple of reviews where people forgot it in their jean pocket and put in the wash and it came out unscathed. However, please don’t try this at home.
  • It has a disappointing user weight limit of 300 lbs but my research so far suggests that this seems to be the standard for pedometers. I scoured the customer reviews to see if someone over the user weight limit was still able to get accurate readings and so far I found one on Amazon for the Omron HJ-303 Pocket Pedometer dated February 29, 2012 here. I plan to research this further so be sure to check in for an update.
  • When you replace the battery you have to reset all your settings again.
  • It tracks in miles and pounds only, not kilometers and kilograms.
  • There is no computer connection but I’m not sure if this belongs in the CON or PRO section because the weekly log can also be used as a backup for when you don’t have access to the internet or your computer.
