For those who have been hiding under a softball-shaped rock over the last few years, data has become an increasingly important part of our sport. Whether it’s statistics about on-base percentages, whiff percentages by pitch location, how much external rotation is being achieved, or other detailed metrics, coaches at all levels are looking to quantify what their athletes are doing to help improve performance.

This obsession also applies to what happens when a pitcher throws a specific type of pitch. Speed is obviously one important metric that has been easily measurable for a number of years, whether it was with a Stalker or Jugs radar gun or more recently with the advent of the PocketRadar.

The other two parameters that are normally listed along with speed are spin and spot, i.e., how the ball is spinning and whether it goes to the location it was supposed to. Spot is fairly easy to determine with your eyes alone; if you know where the ball was supposed to go you should be able to see whether it went there.

That leaves spin. One simple way to determine whether a ball had the correct spin is to mark a stripe or color the seams to make it easier to see the spin direction, then compare that to what is expected for that pitch.

For example, if you’re throwing a curve ball was the spin direction going around the ball at the “equator” (middle of the ball), going from pole to pole (top to bottom or bottom to top), or some variation in between? You also want to see where the spin axis (the point the ball spins around) was, because an improperly oriented spin axis will generally have a negative effect on the quality of the movement.

You can see all of that with your eyes, but it’s still difficult to quantify. And you totally miss another important factor in ball movement: how fast the ball was spinning. You can see if it’s fast or slow, but not HOW fast or HOW slow, which also affects how sharply the ball will break, thus making it harder to hit.

A Rapodo system will give you those types of answers, but those cost thousands of dollars which puts them out of the reach of most individual coaches and bucket parents. You pretty much have to go to a camp, clinic, or measurement event to capture that data, and even then it’s only a single snapshot in time.

In the past, you had the RevFire ball or the Diamond Kinetics ball, which were far more affordable to the average user. But both of those have been long been relegated to the ash heap of history; you can probably still find one on eBay somewhere but all technology has a “best by” date and both of those are long past it.

Fortunately, a new entry into this category was introduced in 2025: the pitchLogic softball. F5 Sports, the manufacturer of pitchLogic balls, has had a baseball version for several years that has become quite popular.

They have now taken that same technology and applied it to fastpitch softball. But is it worth the investment, i.e., does it do the job? The short answer is yes.

If you’re serious about measuring spin direction, spin rate, spin efficiency, and a whole bunch of other parameters and don’t want to break the bank (or your marriage) to do it, you’re going to want to look into this innovative product. Let’s break it down in more detail.

What’s In the Box

This part is pretty simple. It comes with one pitchLogic softball, a Qi-type platform charger, and a short USB A to USB micro cable to connect the charger to a power source. The charger has a small indent in it to keep the ball in place while charging – no O ring necessary (DK ball users know what I’m talking about).

How It Works: The Basics

The pitchLogic softball system consists of two components: a ball with a microchip or some other technological magic inside of it and a free companion app, which you can download from the Apple App Store or Google Play once the ball arrives. The two are connected via Bluetooth, which means you don’t have to have a WiFi signal available to use it.

There are two versions to the app: a player version and a coach version. If you’re a bucket parent who wants to measure your own daughter’s performance and progress, the player version will do you just fine.

It will capture the data from each throw and store it in the cloud for you so you can review it later or even share it with college (or other) coaches. Since you’re only using it with one pitcher it’s really all you need.

The coach version allows you to create a roster so you can track the performance of multiple players, separating them into individual sessions so you can access them as-needed. You just have to remember to select the correct player before you start the session – nota difficult skill but one I’ve already failed on once.

Setting up a player on a roster is easy to do, too. You click on the roster button at the top of the app, click Manage, then click on the plus sign (+) and fill in the requested data. If you want to remove someone from the roster later you click on the minus (-) sign and they are deleted.

The player management section also gives you the ability to share all the data with the pitcher automatically by inputting her (or her parent’s) email address. They will then receive a link that enables them to check it all out themselves whenever they want.

When I purchased the ball it came with five roster spots. If you’re a team coach that’s probably plenty; if you’re an instructor like me it’s not nearly enough, but fortunately you can purchase additional roster spots for an added cost.

Capturing Pitches

Whichever version you have, once the proper player is selected and the ball has been paired to your device, you click on the start session button and then select which type of pitch the pitcher is throwing so it can be tagged in the records. You don’t have to tag the pitches, but it’s definitely helpful, especially when you go back a few days later to review the data or if you want to send it to someone else. Helps to know what type of pitch was being thrown.

The pitcher then throws the pitch and the data immediately shows up on your device’s screen. I generally just use my iPhone because it’s handy, and the key information is pretty readable even to my old eyes.

Hopefully in the future they will add the ability to zoom in by pinching the screen, which would make it even easier while helping the pitcher focus on the right information.

The only caution is that the pitcher has to keep the ball still before she throws the pitch or the app won’t read it. If you have someone who likes to twizzle the ball or spin it in her glove before she throws she’s going to have to remember not to do that for the duration of the session.

So far, I have found that the pitchLogic softball records most, but not all, of the pitches thrown. I’d say it’s around 95% success. Every now and then it will miss one, but it usually captures the next one.

If you have a few missed pitches in a row, stopping the session and then restarting it usually solves the problem. Worst case you can close the app and restart it to reset everything. So far I have not had it totally shut down.

The Data

Ok, here’s where it gets fun. It starts with the clock face, which appears on the top or top left depending on whether you orient your device in portrait or landscape mode. For simplicity I am going to refer to everything’s position in landscape mode.

The clock face gives you three important pieces of data at a glance: the spin direction in blue (including the orientation of the ball), the arm slot in oranage (where the arm was at release), and the last touch on the bal in a darker orange or rust colorl. If your pitcher is having trouble with her spin orientation, that last touch info can be helpful in diagnosing it.

The blue arrow shows the direction in which the ball was spinning. For example, a “perfect” riseball will point to 12:00, a “perfect” drop ball will point to 6:00, and so on. The blue ring shows the orientation of the ball as it is spinning.

So let’s say a right-hander throws a curveball and the arrow points to 9:00, which is the perfect spin for left-to-right. But instead of the ring part being pretty much flat it is a near-perfect circle. That tells you that even though the spin direction was good, the spin axis is tipped either too far forward (most likely) or backward toward the pitcher (unlikely but you never know).

You now know that even though the spin direction was good, you still need to make adjustments to get better, tighter break on the ball. This relationship is also shown under “spin efficiency” at the bottom.

The closer the arrow and ring are being aligned, the higher the efficiency and again the better the pitch will break. Honestly, even though I’d heard that explanation it took me a little time to truly understand. Good news is once you get it it’s pretty easy to understand from then on.

Other metrics that appear along the bottom include pitch speed, total spin or spin rate in revolutions per minute, vertical movement, horizontal movement, spin efficiency (see above), and spin/velocity ratio. Here’s a quick explanation/evaluation of those metrics:

• Speed – How fast the ball is moving. Most people I know who use the pitchLogic softball tend to disregard this reading as it can vary from what a dedicated radar will read. The explanation I’ve heard is that it measures the speed immediately out of the hand whereas a radar gun takes multiple measurements along the ball’s flight path and averages them. The speed readings are sometimes fun to look at but I wouldn’t personally use those as the official measurement because it’s not repeatable when a radar gun is being used.
• Total spin – Super important reading. The faster the ball is spinning the better the pitch will perform, providing it’s thrown well to begin with. You want to push those spin speeds up high, so definitely want to pay attention here. For those who still think in terms of RevFire’s revolutions per second, you can use a little math to draw up a correlation chart.
• Vertical movement – A prediction of how far up or down the ball will deviate from a straight line out if thrown on a straight line out. Upward movement is shown as a positive number, downward as a negative number. Be aware, though, that it doesn’t record the actual movement, just the expectation. I’ve seen riseballs that went straight down with great spin get shown to have pretty significant upward movement so use with caution.
• Horizontal movement – Same as vertical movement, but left to right, with left movement shown as a negative umber right movement as a positive number.
• Spin efficiency – As noted above, this is how much the spin direction and orientation of the ball align with each other. For a curveball, a 9:00 reading with a flat ring would be 100%. You want to shoot for 90% and above. Realistically, you may be surprised how low the efficiency is in the beginning, even on pitches that appear to move well.
• Spin/velo ratio – I haven’t used this one much. I think you have to establish a baseline of speed with a fastball first. Then you’ll see with this reading how close other pitches are to the fastball’s maximum velocity. If that’s not correct hopefully someone will clarify but at this point that’s my understanding.

Those are the home screen parameters. But as they say on the TV commercials, wait! There’s more!

Tucked behind the home screen tabs are additional tabs. For example, in addition to the clock reading you can also see a scatter chart of all pitches for that session (based on the predictions, not actual performance), video if you shot some video (more on that later), and a 3D representation of actual ball trajectory that you can view from different angles by dragging the picture with your finger.

The section on the right, besides showing the basic input screen, also has tabs that let you review specific sessions for that pitcher, each pitch that was recorded, and a more detailed metrics page that shows more in-depth data than the home screen. In portrait view, the “All Metrics” tab appears next to the focus metrics listed in the bullets above.

Reporting

As cool as the in-app data is, the pitchLogic softball can also generate a web-based report that shows you graphs and scatter charts for the entire session that make it easy to see how well the pitcher performed that day. You can also share this information with the pitcher, her parents, or other coaches by copying and pasting the web link into a standard email, text, or other type of message.

Video capabilities included

Another nice feature is the ability to shoot video of the pitch and have it embedded with the rest of the information. I find this very helpful for when a pitcher is struggling to get the correct spin.

For example, one girl was getting good apparent movement on her curve but the metrics said she had more of a dropball release. After shooting video we saw that her wrist was extended back instead of flexed upward going into release.

That visual helped her correct the issue and improve her metrics almost instantly. Seeing, in this case, was definitely believing.

Durability

We all know a tool like this can take a beating, especially if you use it a lot. So far, mine has held up well despite hitting concrete floors barely covered by turf, catcher’s equipment, metal backstops, and whatever else is around for an errant ball to hit.

A nice additional perk is that the manufacturer offers you the option of replacing the cover of the ball every six months on-demand and at no charge. No need to worry if it gets nicked, or if the cover starts to show wear or get slick. They literally have you covered.

Customer Service

This is another area where the pitchLogic softball manufacturer F5 Sports excels. I bought one of the “first run” balls, which had some issues. When I contacted them the people at F5 immediately acknowledged they were having some issues and said they would replace the ball as soon as they had worked out the kinks.

They were as good as their word. The new ball has sat in the trunk of my car through blistering heat and below-freezing temperatures and continues to work great.

That said, their website could use some improvement. For example, there is no place to purchase extra player accounts on the website – you have to contact them to do it. Being able to place an order like that online, with no human interaction, would be much more efficient.

Cost

By now you’re probably wondering what does all this wonderfulness cost? It’s not cheap, but i’s not crazy either.

An individual one-year membership, which includes the ball, the app, and the re-covering option, costs $300. You can save a little money with the two-year membership, which costs $495. Both options require you to pay the full amount up-front.

The website doesn’t list a price for the Coach option that allows for multiple players (and coaches), but I believe the annual subscription is $500. At least that’s what I recall them saying, although the final price depends on how many roster spots you need to include.

Again, not cheap, but when compared to the other options for capturing this type of information it’s a bargain. Especially when you realize it’s much simpler to operate and not fussy at all about how you set it up.

Recommended

The bottom line is that the pitchLogic softball is a tremendous tool for training pitchers to learn how to spin the ball properly in order to maximize their effectiveness in this important parameter.

Whether you want to help just your own daughters/players or you’re helping multiple students, the pitchLogic softball is a smart, high-value investment. If you have the means, I highly recommend purchasing one sooner rather than later. You’ll be glad you did.
