Our Verdict

The Fitness SC2 from Ozo is a full function pedometer, without any of the potentially distracting and costly "extras" that others provide. If you can organize and motivate your step data without the extensive digital memory of a smartphone app, but still want a few different ways to "look at" your movement information, the Ozo is the best value in our test. The Jawbone Up Move, is similar in price, but uses a pocketed sensor and displays virtually all the data collected only in Jawbone's smartphone app and web interface.

Our Analysis and Test Results

The Ozo Fitness SC2 is a basic, yet comprehensive and self-contained daily pedometer. In testing products for years and surveying the market that entire time, we learned that users are split pretty evenly among those that want a full-service app-based data management and those that prefer a self-contained device that does not require a smartphone and app to review relevant data. The Ozo is our highest rated self-contained pedometer. For those that don't want the hassle and expense of a device that requires a smartphone app, and don't need the more sophisticated data management the apps allow, the Ozo is our top choice. It helps, also, that it comes at a very reasonable choice. For this reason, we grant the Ozo one of our Best Buy awards.

Performance Comparison

The Fitness SC2 is the highest scoring product in our test that does not use a smartphone app. Other products beat it overall, but they all require syncing with a smartphone to optimize the data viewing and management.

Depth of Data

There are two main types of data that a pedometer collects. First, there is the "native" data gathered and interpreted by the device. The time electronics, accelerometer, and associated algorithms can be used to report and deduce time, steps, distance, sleep quality, breathing rate, calories consumed, and walking/running speed, among other things. Next, the apps of some devices collect user entered information to correlate with the native information. The Ozo, lacking an app, collects no user entered data. However, of the other categories, the Ozo does better than the close competitors. The Fitness SC2 collects and reports steps, distance, calories, speed, and time.

None of the other non-app based pedometers in our test collect as much information as the SC2. The Top Pick CSX Simple Walking 3D, for instance, only reports an accumulated step count. The Omron Alvita adds a few more tidbits, like distance and time, but doesn't do speed or calories. The app-equipped products, though, have much more robust sets of collected and recorded data. Notably, the Top Pick Bellabeat Leaf manages an astounding array of information, from step count to menstruation, and much in between. Even the other Best Buy winner, the Jawbone UP Move, offers a relatively comprehensive set of information, from mood and sleep to step count. The depth of data on these latter most products is due to the smartphone app interface they employ.

Data Management

We look at three major things regarding data management. First, we consider whether the product employs an app and/or cloud-based data storage and interaction solution or if all information is captured and held on just the device itself. Next, if it is only on the device, we care if and how much data can be stored there on the device. The Ozo has no app, but it does keep the most recent seven days of step counts handy for your review. This is often all anyone needs for motivating and organizing daily activity information.

Data management systems on pedometers represent a fairly wide ranging spectrum. The simplest products, like the Top Pick CSX Simple Walking 3D, have just an accumulating step tally. At the other end of the spectrum are the devices that show significant information on the instrument itself and stores, collates, and captures various types of information on a smartphone app. The Ozo Fitness falls somewhere in between these two extremes.

Step count accuracy of a Pedometer is a tricky thing. To get an accurate step count requires good instrumentation and excellent algorithmic interpretation of said data. Thankfully most products do a good job with this, and many come close to delivering perfect scores on repeatable and repeated testing. However, it is worth discussing, at least briefly, how important accuracy is or isn't. For personal use, comparing one day's action to the next, accuracy isn't that important. In our experience, a given pedometer is "off" in a predictable, consistent fashion. The Ozo Fitness counts more steps than you take by an average of 9.2%. However, it does so fairly consistently. This means that a comparison of data from one day to the next reflects comparative activity amounts fairly well, despite the fact that you see 109% of what you've done.

If absolute accuracy matters to you, you will do better with a different device. Only the Striiv Smart delivered less accurate results. All the remaining products are closer to actual in their step counts. Notably, our Top Pick CSX Simple Walking 3D is similar in price to this Best Buy Ozo, but counts steps almost entirely, with a 0.4% error rate, as compared to the Ozo's 9.2%.

Ease of Use

It is in ease of use that the Ozo and other self-contained devices shine. The Fitness SC2 and other stand-alone devices have instrumentation, storage, and data viewing features all on the same piece of equipment.

The other products require a smartphone app for at least some of the attributes of the product. In setup and use, the Ozo is great. You can see all that the product captures on the easy-to-read screen, and click readily through the fields with an intuitive system of buttons. Our one issue was that, when carried in one's pocket, one of our testers had one instance of data clearance. All of his information was deleted by the device's master reset option. It was inadvertent but not surprising. There is no button lock on the Ozo.

Only the ultra simple 3DFitBud Simple Step Counter and nearly identical Top Pick CSX Simple Walking 3D are easier to use than the Ozo. These two have a super simple function that requires virtually no interaction. The Ozo has a few more features, which appeals to many people but just complicates it a little more.

The Fitness SC2 is a little bulkier than the average pedometer in our review. Thankfully it comes equipped with a fairly secure waistband clip, and Ozo also signs off on the SC2 for regular pocket carry. In any of the carried configurations, the Ozo is indeed bulkier than others but does not impede movement or other pocketed items.

In most dimensions, the Ozo is similar to the CSX Simple Walking 3D. With the pocket clip of the SC2, it is a little thicker. The SC2 is also thicker than the Omron Alvita Optimized HJ 321. Of the devices with onboard screens, only the Striiv Smart is bigger than the Ozo. The tiny Jawbone UP Move and Fitbit Zip Wireless are all much smaller than the Ozo but have little to no on-device data viewing possibility.

Best Applications

The Ozo is a great value and tailored to someone looking for the most basic of data collection. The ideal user of the Fitness SC2 is concerned with his or her daily movement but doesn't need to compare it with others nor to store, digitally, extensive amounts of step count information. Anyone who wants more sophisticated data management will need an app-based device. If the Ozo is even too complicated for you, the Top Pick CSX Simple Walking 3D is the absolute simplest sort of step counter.


Available for just tens of dollars, and providing functionality that exceeds that of many others we have tried, the Ozo Fitness SC2 is a great value. As compared to the other self-contained, comprehensive step counters we tested and have used in the past, the Ozo is the least expensive and the most reliable. We had no hesitation in granting our Best Buy award to the Ozo. If you want app-based data collection at a similar price, we also award Best Buy status to the Jawbone UP Move. The Jawbone is somewhat similar but has no data visible on the device itself.


This model is a classic, full-function pedometer in a sturdy and reliable package. You get all this at a great price.
