RacquetTune for Android

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.
