Designed for power walking and aerobic exercise, the Alvita® Optimized (HJ-321) counts your aerobic steps separately from normal walking steps, as well as the distance, calories burned, and time you’ve traveled, giving you more information about your overall activity level. It accurately counts every step, using Omron’s tri-axis technology. The HJ-321 pedometer also allows for 7 day memory to track all of your activity over the course of a week and has four separate activity modes to provide and even more accurate description of movement. Just wear it on your hip or place it in your bag or pocket.


  • 4 tracking modes measure walking steps, aerobic steps, distance covered and calories burned to show how much you’ve progressed
  • Tri-Axis Technology keeps this activity tracker accurate in almost any position, so you can keep it in your purse, pocket or on your hip and never miss a step
  • 7-Day memory allows you to store and review up to one week of activity data

Product Reviews

Omron Alvita Optimized Pedometer is rated 3.9 out of 5 by 13.
Rated 4 out of 5 by from some thoughts I have my second pedometer now. The first one was lost. Apparently there is no way to secure the unit to your clothing. Nothing is included. So I improvised and failed to note that the holding clip is too small for a normal belt, and does not securely hold the unit if brushed by clothing. Surely a lanyard of some sort with a clip on it should be included with the purchase. Sort of a pricy lesson. Other then that the unit does seem to work fine. The instructions could be streamlined just a bit. The included ones are way to wordy.

Rated 5 out of 5 by from I Think it's great! This is very simple to operate. Just read the manual for easy setup instructions and go. I don't know if the readings are accurate, but I see it as a day-by-day comparison of my activity. Just keep steps above 10000 per day for a person my age for reasonable activity. It measures calories, aerobic steps, step pitch, etc, and saves all for a running 7 day record. It resets numbers automatically daily. The only slight complaint I have is the units display is small for my aging eyes.

Rated 5 out of 5 by from Teeny-tiny Pedometer Wow, so much product packed into such a small package. What's great about this little pedometer is that you throw it in your pocket and it keeps track of not only your steps, but your more energetic (aerobic) steps, the calories used, and the miles exhausted plus you get a week's worth of data to run comparisons if that's your thing. I found it easy to set up and very very convenient.

Rated 5 out of 5 by from Accuracy and everything I want to know I have been using pedometers for many years. Since the pedometer gives ma e alll the info I want I am not interested in the "fitbits" or other fitness measurement devices. I loved the Omron larger pedometer # 75 (I think) but it needed battery replacement and could not be put in a pocket as this pedometer can. And I really like this pedometer's accuracy no matter how I locate it on my clothes.

Rated 1 out of 5 by from horrible example of terrible instructions I sent the first one back after buying batteries in the event the one that came with the unit was weak. The second unit, the same as the first, can't be set. The instructions are simple incomprehensible and don't work.

Rated 4 out of 5 by from Easy to use Used this daily for the last 6 months and it worked great! Lost it in the Anaga Mountains of Tenerife, Canary Islands, Spain. Must have slipped off of my waist, wish I had kept it in my pocket...

Rated 1 out of 5 by from Very Very Very Poor Assembling Instruction Pedometer Model HJ-321BULK came with 7 Series Blood Pressure Monitor Model BP761N purchased from Sams Club. The "Assembling the Strap" instructions is not comprehensible and does not guide one to accomplish the task, Omron rep that I spoke with was unable to help! The instruction manual that came with the unit is DIFFERENT from that on their website! The illustrations are very tiny that it cannot be read. If I cannot assemble the unit then I cannot use it! Could have given it less than one star iif that was possible. The product is good BUT the instruction to assemble it is poorly written. The BP761N blood pressure monitor did not come with a carrying case! Also, there was no electric adapter to connect to electric outlet!
