App crashes

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

Works really well!

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!

A nice addition for this tool

Nice addition this tool would be to manually input seconds to check formula.

Great value!

Excellent inexpensive app for measuring swing weight of tennis racquets.

Okay

When used properly I think it is pretty accurate but the app sometimes gives fluctuating swingweight numbers at times despite same numbers inputed
