From the Manufacturer

Alvita Optimized Pedometer

Alvita means lively. It’s how we hope you feel, how you act, how you live, all the time. And when it comes to staying fit, the Omron Alvita Optimized Pedometer not only helps you walk the walk, but jog the jog and run the run.

Whatever activity you want to monitor, this pedometer can handle it. It knows the difference between normal walking steps and more brisk steps, counting both separately. Plus, it can tell you how many calories you've burned to help motivate you further.


In the box
  • One Pedometer
  • CR2032 battery installed
  • Holder
  • Screwdriver
  • Instruction manual

Walk with purpose

Your health is important, so you probably want to concentrate more on your fitness plan than your pedometer. Just clip this on your hip or place in a pocket and you’re good to go.

  • Tracks steps, aerobic steps, steps per minute (pitch), distance and calories burned
  • Tri-Axis technology keeps an accurate count in almost any position–flat, vertical or horizontal
  • Includes holder so you can clip almost anywhere
  • Displays 7 day’s activity on display
  • Automatic reset at midnight helps you easily track your daily steps and distance

Key features

Steps

A little motivation goes a long way. Increase your total number of steps a day by 2,000 or about 1 mile when using a pedometer or tracker.

Distance

Experts recommend walking 10,000 steps a day, or around 5 miles to lose weight. Most average about 4,500 steps so hitting 10,000 may be easier than you think.

Calories burned

Just walking 15 minutes a day, every day, can burn an average of 420 calories per week (or roughly 3 cupcakes worth).

Aerobic steps

What's the difference between regular steps and aerobic steps? Anything over 60 steps/minute counts as aerobic steps, and it's that kind of activity that helps you stay healthy.

I have had four different pedometers in the last five years. I think they are fun and I believe that they do have the effect of making me walk more. Every one of those pedometers has been made by Omron. Omron seems to have the pedometer space locked up. So, in writing this review I want to spell it out that the choice is probably not between Omron and another brand but rather between this Omron and another.

The HJ-321 is a sensitive pedometer that does a great job of differentiating between motion and steps. This is its real strength. Today I went for a "walk" in a museum. While I did move my feet, most of my movement was made up of small shuffles and not of real steps. The HJ-321 ignored by shuffling. Although I spent two hours on my feet in the exhibit, the HJ-321 only counted about 500 steps. If sensitivity is good, then its size is also a plus. This is a very small object. It is not obtrusive at all.

It has the advanced functions that were not available a few years back: aerobic steps, 7 days of memory, and calories burned. It also has regular steps and distance, but of course those have been standard for years. The LED goes blank when you are not using it but the system is still tracking your steps.

My all-time favorite Omron is the HJ 112. That pedometer has the same advanced functionalities but it differs in how you use it. It is easier to check your steps, because unlike the HJ 321, its LED is always on.

The main difference is how you keep it on your body. The 321 has a very small clip. It does not seem trustworthy. Pedometers tend to get lost. Indeed, I lost my previous three pedometers. The 112 had a great clipping system that easily affixed to a belt, a waistband, or a pocket. My 112 remained on my body for over a year.

I received this shortly after I got a Fitbit, so I got to compare the two. They're both very lightweight and work similarly, in that you can put them in a pocket or bag or clip them on anywhere, unlike other pedometers that have to be positioned a certain way. Unlike the Fitbit, the Omron has to be calibrated by measuring your steps and entering the measurements; Fitbit guesses your step length based on your height, or you can enter steps manually. I found that Fitbit counts about 10 more steps on average than the Omron, but the Fitbit is better at tracking when you're fairly active and very active, even for just a few minutes. Omron only counts "aerobic" steps if you take more than 60 steps per minute for 10 minutes.

Both of them require you to push a button to see the display - I'd rather have that than have the battery run down quickly. Fitbit's backlit display is easier to see in a dim room while the Omron's is much easier to see outdoors or in bright light. Both also have distance, calories and time of day.

Of course, the Fitbit has the extensive online tools and graphs, and mobile apps, that the Omron doesn't have, thus the vast price difference. But if you're not going to use all that, then this is a good alternative. I also like how you can see information for the past seven days on the Omron by pushing a button; the Fitbit stores that info but you can only see on the device the steps for the past day.

I have several pedometers from very good to horrible. The very good pedometer accurately counts my steps while I am walking. However it also counts steps if it is just sitting in my car. I compared the "good" pedometer to this Omron HJ-321 and Omron wins. It accurately counted my steps as I walked around the house and up and down stairs. As it rode in the car for an hour to work, it counted 12 steps while the "good" pedometer counted over 200. I attached a strap to it with a clip so I could have a backup in case the enclosed clip failed. The clip that comes with this pedometer has teeth kind of like velcro so it clings to the clothing and is not to likely to slip off. The pedometer slides into this clip so if you want to carry it in a pocket, you can just slide it out of the clip. It is small and slender so no one has to know you are counting your steps. One day I carried it in a shirt pocket and another clipped to my waste band. When I took a quick two mile walk, it measured my steps and also counted the time as aerobic steps. I was able to set up my stride length so it also calculated the distance I had walked. For the price, this is a great pedometer. I compared the price of this one to some offered in a large chain department store and for the same price I could get a piece of plastic that requires a small earthquake before it counted steps.

In addition to counting steps here are a couple of other pluses. The display turns off and it continues counting steps so you don't wast battery power. Did I mention it uses a battery? The buttons on the front are almost flush with the ped so you don't accidentally clear your steps during the day. It stores several days of steps so you can monitor how you're doing over time. The only thing missing that I wish it had was the ability to upload my steps to my computer. For that I would expect to pay a lot more.

As a former track athlete, many pedometers have passed through my hands over the years. The Omron HJ-321 Tri-Axis Pedometer is the most accurate step counter that I have ever used. In this review, we will examine its features and see how a tiny electronic device can make a big difference in your overall health.

The Omron HJ-321 Pedometer has many features that can help encourage you to move around more daily. First this pedometer uses special 3D Smart Sensor technology to register your movements. Older pedometers like the Nintendo Pokewalker could only register a swinging movement along a single vertical axis. As a result, your side to side movements would not get calculated as a step. With this Omron pedometer you have the freedom to more sideways or lift your legs and know that those steps will get counted. My daily movements can be quite erratic as I often have to climb steps while working daily. The Pokewalker could not count these as steps so I often felt cheated from my real step counts.

Second, the Omron HJ-321 pedometer has a seven day memory feature which not only counts your daily steps in a virtual log but also shows your distance, calories burned, aerobic steps and pitch. The 3D sensor is key in generating these additional statistics about your daily exercise routine. The sensor seems to be so accurate that you can wear this pedometer around a chain on your neck and it will continue to register steps!

Now, let's discuss the one feature that I enjoy the most about the Omron HJ-321 Pedometer, the aerobic step counter! For the past seven days of use, my pedometer showed 0 for aerobic steps even though I had at least 6,000 steps counted each day. The reason was that my walking behavior is in bursts that last for less than 10 minutes at a time.
