    • It's cheap. Just do it.
Recommended by Dr. Roizen as one of the pedometers for doing 10,000 steps a day, no excuses. Very simple to use. Battery lasts and lasts. Gives you all the helpful information you need without all the complexity of a modern health app. I use it all the time since I bought it and have yet to put in one of the eight new batteries I bought. I count steps every now and then and it is accurate for me. Yes, I have the step measuring app on my iPhone, but I don't have my iPhone on my person too many times, and in many of the activities I do, the iPhone is a bit too bulky or the risk of breakage too great, so I have it nearby. This pedometer is small enough to fit in any of my pockets and is oh so innocuous and can easily be ignored until you want to check up on how you are doing. It is light, but heavy enough, smooth enough and compact enough not to get lost or feel unwieldy in a pocket. Packs up real nice next to credit cards or folded bills. What I didn't want is a gadget to rule my life. My body doesn't care what I record. What I understand is that the more steps people did, up to 10,000 a day over a wide range of people, some moving slow, some fast, some all at once, some spread throughout the day, the healthier they were over time. After 10,000 steps it didn't seem to matter much for most of us, but up to 10,000 there were serious, healthy improvements. What this device does is take the guesswork out of knowing what is actually being done. This is the baseline that we all must do to stay healthy, and we need to do it every day. Dr. Roizen gives substitutions for cycling, running, swimming and other exercises, but if you are caring for kids, time might be an issue, and this might help to get in what we need to do every day, and help others know if we are not that it is hurting us. What I find is that some days I can easily do 10,000 steps, but other days I fail unless I stop making excuses for myself and put my mind to arranging my life to get this in, every day, no excuses. For example, I can walk back and forth in a space just big enough to pace say 10 feet back and forth while I am waiting for something else to happen (a lot of my life it turns out) and, it turns out, I can do thousands of steps that way, changing largely wasted and unscripted time into improving my health and lifespan. All for the small price of this small gadget. When Dr. Northrup talked about improving our health on stage, I noticed she was pacing back and forth across the stage. I wondered what she was doing. My guess now is that she had a pedometer such as this one and was modeling using pacing while presenting to get her steps in. For me, the most problematic time is driving. I often end up driving a lot, and it is stressful and extremely dangerous and requires full attention, no distractions, and leaves me mentally exhausted when I have time in between driving, and have nothing motivating me to get my exercise in. What I have found is that this little gadget is a big help to my motivation, particularly because even a few minutes need not be wasted, and often that turns into a lot of time that is not wasted, and I end up getting my steps in. Thanks for the recommendation Dr. Roisen, and thanks Dr. Northrup for modelling how even on your type of schedule we can get our steps in. ... show more

    • Does everything, and most importantly: The controls are simple and intuitive
This does everything my previous pedometer didn't, and does them well. I can't knock the previous one because I bought it for something like two bucks at a Daiso, but... with this nearly-as-dirt-cheap Omron you do not have to worry about it mysteriously and randomly zeroing itself , and the controls are a model of intuitiveness. You push the "mode" button to cycle through units like Steps, Distance, Kcals and the like, and one of the modes is Clock, a bonehead-simple but invaluable thing for runners who just want to time themselves. I did a few experiments with direct measurement and the accuracy is spot-on. It stores up to seven days' data and automatically resets to record the next day's data set at midnight. To access it, all you do is push the "mem" button. Every time you push, it steps one day into the past. For each of those days you can jump to the "mode" button and look at steps, distance, calories burned. If you want to delete, you just press and hold and it will cycle through and delete each day - but with enough time to let go if there's a day you want to retain for whatever reason. If you're a professional or Olympic athlete with need of heavy-duty precision you might opt for some high-dollar alternative, but for the standard runner or simple fitness buff who's looking for a reliable measurement tool, this is well-designed, reliable and hassle-free to operate. ... show more

    • Simple, light and effective
This simple pedometer has a couple of features that drew me to it. First, you can carry it in your pocket easily, which helps me remember to take the darn thing with me - I just put it next to my wallet and keys at night, and rarely leave it behind. Because it's so small, I don't even notice having it with me throughout the day. Second, it has a 7 day memory, which makes it easy to look back over the week to check my progress. I set a few walking goals a while back, and the rolling memory feature makes it much easier for me to track them. I definitely understand the appeal of more advanced tools that will track and save that information online, but I was looking for a cheaper and simpler solution than that. With this, I just set a reminder for myself to log the information manually every Friday, and I'm all set. Finally, I really like the information that gets tracked, which include total steps, distance traveled (based on the stride length you enter at setup), calories burned, aerobic steps and steps per minute for each day. Honestly, I have no idea how accurate the aerobic steps or calorie measurements are, but it's interesting information that I use to compare one day to another, rather than as an objective measure by itself. Overall, I'm quite pleased with this little pedometer. It's simple to use, has a reasonable number of features, and hits a decent price point for what it is. ... show more
