RacquetTune - String Tension

This App can help you to Jeep track of your racquet tension variations which can help you to better understand and improve your game. Recomended for casual player and a must for stringing machine owners.

I recently purchased Racquettune after reading positive reviews, but unfortunately, I haven’t been able to use it yet. I keep getting an error message saying, ‘You must pick a racquet and a string,’ without further guidance on how to resolve it.

To get it right, get a new string on your racquet and play with the value of the string factor until match the value tension of you new strings.. it works for me 👍

I restrung my racquet at 55#. This app said the tension was 40.2# right after I finished. I checked the string factor and ensured that I’d entered the correct values all the parameters (e.g. string pattern, racquet face size). I followed the measurement procedure to the letter. I could believe a couple lb. change but 15? Nyet. The racquet plays like 50-55. A Gamma String Tension Tester said the two center main strings were at 55# and the two center cross strings were at 39 and 40#. Why are other users getting numbers close to the tension at which they strung? Not even close for this app. Sorry

Don’t waste your money

It’s almost too good to be true. I get readings and I think, no, it must be wrong. It can’t be a mistake a made. Sure enough, I did something wrong. When I string exactly the same, I get the exact same output. This is an amazing app. It has helped me string better and learn more about how my string tension changes over time. Well done!!

I place the phone on a table, lay the racquet about an inch above it and use a wooden spatula to hit the strings. It has a delta of +/- 4-5 lbs and is hard for me to trust.

I have had this App for a week now and the results have been much better than expected! I use it to find out how much tension drops after each playing session.

Fantastic app. Incredibly useful to graph how the racket loses tension over time. Readings are very accurate. (note, if I’m stringing a poly, I can sometimes lose up to 10% by the time it’s off the stringer, then maybe another 10% over the next 48 hours) String factor accuracy is crucial, and the online database can be hit or miss, you’ll see lots of variation in there. You should measure this yourself to make sure it’s accurate, because it will greatly affect the reading. I use the weight method, and that’s worked out well for me so far.

It doesn’t give you consistent tension. It gives me different tension every time. Total garbage.
