App Reviews

  • Strange UI choices; Solid tuning.

    By nerdgod
    App installs itself in the menubar. So when you open it for the first time, it doesn't show up. (And at least in version 1.3, the menu icon doesn't have an inverse mode for Dark-Mode menubars). Once you realize that it's in the menubar, it's a decent app. The app works best if you disable "Use ambient noise reduction" in System Preferences -> Sound -> Input. The "Historical" mode is probably the most useful, but isn't the default. There seems to be no way to toggle the mode shown in the preview image.
  • Does not open.

    By BassTbone46
    I just downloaded this app for my MAC. It will not open. I feel like I have been scammed by this company. Apple needs to take this out of its App Store until the company can verify that it actuallly works. Once it is working, the company should provide a free upgrade to all customers who have purchased this app.
  • Great tuner

    Meets my tuning needs.
  • Gave it one star because zero was not an option

    By The Pinkoboe
    This program opened up once and then crashed. I cannot get it to open. A complete waste of money.
  • a bit behind the iOS version

    By ipodtouchguru6
    I really love the iOS version of the premium version. I’d say the best feature on there is the transposition feature. I play the trumpet, so it’s very important to be able to see the notes for non-concert pitch instruments. The free version of this OS X version was pretty good, and I thought I would get more by upgrading. Honestly, I’m kind of sorry I wasted $3 on the upgrade. The additional features are buggy on this version (I’m running El Capitan for what it’s worth). The tuning seems to stop after a few seconds and shows your pitch frozen, as if it stopped listening. Once you play a new note, it shows your pitch for that note for another few seconds, then freezes again…kind of weird. I was really hoping to see the transposition feature on here like the iOS version. Hopefully you guys can add it as a free update :) It seems like the free version works better than the paid version. Developers- you might want to look into that.
  • Works great on Mavericks

    By Sonimanec
    I installed this on Mavericks and it works great. Thanks
  • terrible app

    By Trumpetman88
    I got this and it simply doesn’t work. It is very difficult to turn off unless you figure out how. I strongly discourage anyone getting this. What a piece of crap. You can’t erase it because it says its in use, but nowhere to be found. I had to restart to get rid of it. DON’T DOWNLOAD THIS!!!!!
  • What’s all the kvetching about

    By fjjh
    Works great - I have eveyrthing from classical accoustics to steel string concert bodies. Works just fine on electric. I keep it open while I’m practicing to music - you can pretty much dope the key progressions without a chord chart, etc. It’s really handy.
  • Best Free Tuner - Acoustic Guitar

    By Skykid14
    I use the app to tune my Acoustic Guitar. I primarily use the iPhone version of this app, but the OSX version has been working just as well for me. I find the interface for the OSX version is a little more simplistic; I actually prefer the more sophisticated interface of the iPhone version. However this OSX version manages to detect when my guitar is in tune just about as well as the iPhone version. I should also mention that INSTuner offers the most precise feedback of all the other tuners I have tried on the app store. I think it’s a very well designed app and it does exactly what I need it to.
