★★★★★ "Does not function well. This app says one of my racquet is 23 psi. It also says another racquet is 54 when I know it is 60 psi. All of the shock absorbers are off of the racquets. Mind you this is after plucking the string 99 times." - Boombostic

Stopped picking sound after iOS 26.4 update
Hey Sten, would you please update the app? The app was still picking up my tapping before the 26.4 update. It's completely dead now.

Keep getting the error messages
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.
Not accurate
Don’t waste your money
Not reliable
It doesn’t give you consistent tension. It gives me different tension every time. Total garbage.
Bogus. Save your money
Doesn’t work plain and simple. I knew better. Just a toy.

This app says one of my racquet is 23 psi. It also says another racquet is 54 when I know it is 60 psi. All of the shock absorbers are off of the racquets. Mind you this is after plucking the string 99 times.
Don't buy junk
Don't waste your money, this app is TERRIBLE do not buy
Not a great tool for badminton
Not a very great tool for badminton not very accurate... Also test on test all over the place wish haven't purchase
Doesn't work
I'm tapping. I'm banging. Nothing.
Don't buy this!
I really want my $1.99 back. I've been stringing tennis racquets since 1994. This App is a sham.
Lost my money
Does not work... Not accurate
4.1 Version solved previous problem
Developer Sten Kaiser worked very diligently to solve my problem with version 4.0. Once again a fantastic app that I use on a near daly basis
Sorry can get it to work! Tried different raquets and objects. Save your money
Doesn't work
Junk
Totally useless.says my tension is 35lbs.A waste of money.
Not for racquetball :-(
Bought the app for my racquetball racquets several months back and disappointed the app doesn't support the sport. Let's have an update already.
Clunky, no longer works
I used to love this app. The UX isn't intuitive but that was ok. But I can no longer get the tension analyzer to work, making this app useless for me
Pretty inconsistent
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.
Not consistent or accurate
90% of the time I could no get the app to pick up a tension despite following the guides
Racket strung at 47lbs confirmed on ERT tension tester machine. When I got racket tunes to pick up, it showed 58lbs. Used the correct string set up.
At best this app might be able to tell you which of your rackets is strung a bit tighter. But that’s all. Just a gimmick.
Wouldn’t waste your money

Doesn't work with hybrid strings
I'm using hybrid strings (VS Touch and RPM or Solinco Tourbite) with different tentions for mains and crosses and couldn't get a consistent display. Spend quite some time to try to get the string factor setup right with no luck.
Does not work as described
Strung Babolat PD 107 today at 54 reads 41.3 lbs.
TiS2 strung yesterday at 55 today reads 49.
Not happy.

Not for Racquetball
This app is based on measurement of the frequency of vibrating strings and requires that there be no dampers on the strings during measurements. Unfortunately, racquetball racquets nowadays tend to have integral or non-removable damping elements, so this type of app will not work.
Hmm
I can't seem to make the whole racquet tuning thing to work properly. The tension deal was 10lbs off also.
