Have you ever been listening to a song, or have a friend playing some chords and want to know what key the song is in?  This app could help.
This little helper can be used to identify the key a song is in via several methods:
 * Analysing live music via the devices's microphone 
 * Analysing a local audio file on the device
 * A set of user-entered chords 
All analysis is performed locally on the device, so doesn't eat through your data allowance.
The results of a scan can then be saved to be referred to later if required.  
If there is a song that changes key part way through, on the song detail page you can enter the chords, or analyse via the microphone while you play that part of the song.

    Suprisingly super accurate. I played it some songs I know the key of and it guessed correctly on every try with the live audio function. Good stuff. Can't wait to utilize this app in live jam sessions.

    Yeah good app could be five stars if it worked for me offline. I kept trying but when I was online then it worked!!! Hope the app is not removed and replaced in the future.

  3. guest-avatar

    Works for me. Was having trouble finding the key of songs. Thanks.

  4. guest-avatar

    Was five stars but in last month or so it just freezes and doesn't give me key info....i tried multiple restarts or several l weeks

  5. guest-avatar

    Works ok for about 15 minutes then dies, not very accurate. The details are that it does not always show the correct key and after about 15mins it doesn't register anything.

  6. guest-avatar

    The "Scan Live" function doesn't work at all. I played a song that I know it's in C major so I can test the accuracy and the app said it's F minor so yeah it's useless.

    ive been using this to sing my own songs into to see what notes and key my voice register, it was correct at the key. for this reason alone I would buy it, except... if you use the function for adding chords/notes/keys sections, there is no way to change or add a key without it being placed at the end. So if you messed up the first (like me) you have to delete and re add everything to get your order back. Make some changes here and i'd donate. not used it for known songs so cant comment.

  8. guest-avatar

    Tells you to record longer for better accuracy, but provides no info on HOW to make the recording (via mic) longer. Records for ONE second (one thousand one) and gives inaccurate results.

    I'm sorry but I just could not figure this app out. It may be a good app as far as transposing and such but with no guidance as how to take the desired song and transpose it into a workable key it was just to complicated to do. I just wanted to be able to play the song and have the app transpose it one key up or down and the touch of a finger until I found the key that was right for me. Never got that done.

  10. guest-avatar

    this is very helpful... the first time an app can detect a real key.. thank you very much...

  11. guest-avatar

    The app works fine and its accurate. But the UI could be more "modern looking".

  12. guest-avatar

    Not working for wav files. Doesnt even see mp3 files.

    Install, select MP3 to analyze - nothing happens.

  15. guest-avatar

    Chord detection should also be provided along with the scale detection!!!!

  16. guest-avatar

    I gave it 5 stars because it is the best key finder app ever. I would recommend it to anyone.

  75. guest-avatar

    Uses only I ii iii IV V vi vii° So it can't resolve minor keys. Am E7 says "no exact match found". any diminished chord must be the vii, etc. Works fine if you use only Major or Aeolian progressions

  76. guest-avatar

    Inaccurate results. Play same songs 3 times but got 3 different results

  77. guest-avatar

    The app is awesome, very accurate. It does what it's designed to do. The only problem is that it fails to listen to some songs, please fix that.

  78. guest-avatar

    Doesn't always gey the key correct, if you want to check out a few songs then it stops recognising the key after repeated use requiring it to be restarted.

  79. guest-avatar



    Did not find it useful 🤔

  80. guest-avatar

    Didn't find anything

  81. guest-avatar

    Not on point

  82. guest-avatar

    Just awful. Most time it says it is in the key of . (dot). I played a few songs on the piano in simple major and minor keys, and the app got one out of five correct. Too bad, I'd like to find an app like this that works.

  83. guest-avatar

    I have been cursed with perfect pitch, (ask anyone with it, they'll explain) so I don't need this, but I wanted to test it out. Works perfectly! Awesome work! 😀

  84. guest-avatar

    Works for basic root determination and Western major/minor relationships, but if you're dealing with anything outside of that scope (ie: different modalities, chromaticism, etc) it's unable to function quite as intended.

    This app decent asl. I'm actually impressed they can find a key to a song in a matter of seconds. That's pretty neat 🙌🏿💯

  86. guest-avatar

    This app needs work; simple and easy interface; inaccurate though- every song is B major.

  87. guest-avatar



    Woooaw!!! this is marvelous, it had been a long time that I've being waiting for app like this. God bless the creator of this app. Thank you very much. Even though I have not tested it.

  88. guest-avatar

    What dose transpose do after I've scanned an mp3?

  98. guest-avatar

    Really useful.

  99. guest-avatar

    I have just uninstalled this otherwise excellent app because I won't be subjected to extortion. After several months use I have just been offered the choice between letting a third party use my private data to give me UNPERSONALISED ads and paying money for the app. I might have been prepared to pay, but won't be blackmailed.
