Features & Capabilities

SwingTool can quickly and easily measure the swing weight of tennis racquets, golf clubs, baseball bats etc. Swing weight is the most important parameter when deciding how a racquet, club or bat feels when you swing it. Unfortunately measuring swing weight has been fairly complicated, until now. With SwingTool it is enough to just hang your equipment and let it swing like a pendulum. Place the iPhone close to the swinging end and it will automatically display the swing weight.

Characteristics

Can be used for all types equipment
Choose any point to calculate the swing weight at
Choose any point to hang the equipment at (independent of the swing point)
Faster and more accurate than the traditional way to measure swing weight
Can be used to measure the swing time of any pendulum with 0.01 s accuracy

A demo video is available at appmaker.se/swingTool

To golfers: With this app you do MOI-matching i.e. it measures the real dynamic swing weight (moment of inertia). Not the static Lorythmic balance point (D9, C4 etc) that sometimes is called swing weight.

User Reviews

SwingTool is praised for accurate, repeatable swingweight readings and strong value, especially after proper jig/setup, with quick developer support. However, users report startup crashes, vague error messages, and a demanding setup that relies on external guidance. Some measurements fluctuate and can be unreliable at times. Overall, it’s a solid, affordable tool for racquet tuning if you’re willing to invest in setup and consult external instructions.

Pros

Highly accurate swingweight readings that align with manual measurements and even professional machines
Easy to use and repeatable once the setup (jig/stand) is in place, reducing human error
Inexpensive tool providing good value compared to dedicated swingweight machines
Consistent/reproducible results and a solid reference point for comparing racquets
Responsive developer support with quick responses to issues

Cons

Crashes on startup / stability issues when launching the app
Instructions are lacking; users often need external guidance (e.g., YouTube video) to learn usage
Error messages are unclear or not helpful during use
Setup can be complex, requiring a jig/stand to swing the racquet (the hardest part
Occasional fluctuations in measurements despite the same inputs, raising reliability concerns

Recent reviews

App crashes upon opening. Doesn’t work. Apple should take off their approves app list site.

I downloaded this app because I wanted to tune my tennis racket without spending $300 on a swing weight machine. I found it to be very accurate and easy to use. However, the instructions on how to use it are lacking, so I recommend watching the only YouTube video that talks about this app to help you get started. Look for the video from the channel “No Limit Tennis” titled "How to Measure Swingweight Without a Machine." This should guide you through the setup process. Overall, I have been very pleased with the app!
