  • Doesn’t work

    I have the iPhone 11 Pro. The app doesn’t register that it is picking up sound. I have deleted it twice, downloaded it three times, rebooted my phone twice, and even updated my phone and redownloaded it after that. Nothing has resolved it. I open the app, ALLOW it to access my phone’s mic, and then make a whole bunch of noise, but the virtual needle remains on the default “C”. Nothing changes. Ever. Bummer.

    Hi there, we've released a new version of the 432Tuner which addresses this issue, please download the new version (4.3) and see if it works for you. If it works I would truly appreciate if you can update your review :) I can only say the I'm sorry it took so long to fix, it was a hard bug to find. Much blessings, 432 Team
  • Always a pleasure

    This is my
    Go to app when I don’t feel like using my hardware tuner. Makes my ukuleles sing
  • It works

    A great app-based tuner. Sounds good to me!!
  • Does not work on my iPhone 11

    Worked on my iPhone 7 but not my new 11
  • Simply the best!

    I’m a fan of this tuner. Plain and simple. And it’s free. All the best things are free. Sunshine, Love, and this tuner. Do yourself a favor and get this thing. Oh, and don’t forget to tune your guitar (or whatever instrument you happen to play) to 432 or 444 and just feel how that feels...Thank you 432 tuner!!

  • Junk

    This thing does nothing. Does not respond to anything. Useless.
  • Was good, now improved! Love this alternative frequency tuner!!

    This app started out solid but has gotten even better over time! I love that I have easily accessible options for tuning to standard (440Hz = A) or the two most common alternatives- 432Hz and 444Hz = A. It makes it easy to experiment and easy to tune back if playing with others who don’t want to experiment lol. Also I love that it shows the actual frequency so if you did want to tune to another frequency altogether, you could tune any string to any frequency. One of the biggest improvements they’ve made is smoothing out the interface and tuning needle. Tuning is fast and easy!

  • Used for years but...

    I used this app for a few years and it worked flawlessly. Then I had to update my iPhone to an 11. Now the app just stares at me. It works on my iPad Pro but won’t respond to sound. I restarted, reinstalled, etc. the mic is on and permission is granted for the app to use it. I’d like to keep using it. Any suggestions?
