  1. Danny, October 10, 2012:

    Got it. Nice looking app! Finally, there is a jazz guitar app for ios.

  2. Matthew Warnock, October 10, 2012:

    Thanks Danny, glad you dig the app!

  3. Tesh, October 10, 2012:

    Just played around with this for the first time but had to write a review. Really useful if you are trying to tell your drop 2’s from your drop 3’s on different string sets and most importantly suggestions of how to practice and use them. The sheer number of permutations available here is almost limitless (well probably not but you know what I mean…)
    Apart from providing the grips for all the various chords, in all the inversions there is an inbuilt metronome and practice tips!
    I particularly like how you can adjust one one note at a time (as in a single chord) as you tweak your 251… really helps internalize a particular shape/grip…
    Thanks Matt. Brilliant app!

  4. Matthew Warnock, October 10, 2012:

    Thanks Tesh, glad you like the app, very nice of you to review it!

  5. Danny, October 10, 2012:

    You should work up a scales and arpeggios app next. Or add on to this one.

  6. Matthew Warnock, October 10, 2012:

    those are already in the works for 2013!

  7. peter, October 10, 2012:

    Said you were on a winner with this.Will only improve with time Great app,

  8. Alex, October 10, 2012:

    Hi Matt,
    Any chance of an Android version?

  9. Matthew Warnock, October 10, 2012:

    Thanks Peter!

  10. Matthew Warnock, October 10, 2012:

    Working on that right now Alex, they come out at different times but it shouldn’t be long.

  11. Alex, October 10, 2012:

    I’ll just have to be patient then :)

  12. Leonard Henriette, October 17, 2012:

    Hi Matt,

    This is not criticize, but to ask you to also remember that there are poorer third world musicians that barely made it to the internet and are not yet iPhone owners.
    Really this is not meant to criticize, but if your app can be made available for more accusable platforms it would reach more upcoming jazz guitarists or guitarists in the making. I am assuming here that this app can only run on iPhones because I am not that familiar with compatibilities etc.
    Congratulations on all the good reviews and your great articles.


  13. Rich, October 17, 2012:

    Hi Matt,
    Just got the app

    The fingerlings are stretchy

    I like the different sounds I’m getting

    Can you demonstrate some of these 2 51. In a video


  14. Matthew Warnock, October 17, 2012:

    Leonard. We released the iTunes version first since it is the easiest to build. Next we are adapting the app for android as well as a desktop version for mac and pc. Should be ready by the end of the year.

  15. Matthew Warnock, October 17, 2012:

    Thanks rich glad you are digging the app. If you go to the Matt Warnock guitar YouTube channel I have a few videos that you can check out where I play through a number of these progressions. Cheers

  16. Jesse Mazzoccoli, October 27, 2012:

    Once again, great job, Matt. Does this or will it come available for *Androids? Thank you.


  17. Matthew Warnock, October 28, 2012:

    Thanks Jesse, it’s being developed for Android right now.

  18. Nelson Branco, October 31, 2012:

    Hi Matt!
    When your chord app will be avaliable for Android version?
    Nelson Branco form Brazil

  19. Nelson Branco, October 31, 2012:

    Matt, I was too quick on the trigger!!! now I see the your previous response on the same question!! thanks!!
    Nelson Branco

  20. Gary, November 17, 2012:

    Hi Matt!

    Once I found your 251 app I finally knew what I was missing. Thanks!

    Are there iPad guitar interfaces that will work with the app? I have an Apogee Jam but can’t get both running. New to iPad so I may be doing something wrong.


  21. Matthew Warnock, November 18, 2012:

    Hey thanks for checking out the apps. IPad habeas trouble running two programs at once so it probably won’t work. But we have written a desktop version that will be out shortly and that will work with multiple programs at once.

  22. Leonid, November 29, 2012:

    Your works deserves respect. How about Android platform? Thank you very much!

  23. Matthew Warnock, November 29, 2012:

    Thanks! The Android version is in the final stages of development. Should be out soon!

  24. crimson, December 3, 2012:

    Can we download with our desktop p.c. using Microsoft o.s.

  25. Matthew Warnock, December 3, 2012:

    Hey, right now the Android version is in the final stages, then we will develop it for PC Desktop.

  29. Matthew Warnock, December 14, 2012:

    Leonid, the app is now ready for Android phones!

  30. Alex, December 14, 2012:

    Thanks for letting me know Matt. Unfortunately it won’t work with my version of Android (2.3.6). Guess I’ll just have to wait for the desktop version.

  31. Matthew Warnock, December 14, 2012:

    Sorry man. Some older phones or versions of Android are not compatible, the app won’t run properly on them.

  32. Alex, December 14, 2012:

    Not your fault mate. The annoying thing is that my phone’s only a month old! It seems my provider’s not in a hurry to release the Android upgrade.

  33. Matthew Warnock, December 14, 2012:

    Tough luck. Well when you carrier releases the update the app will be waiting for ya!

  34. mark, December 26, 2012:

    Hi Matt,

    You are doing a great job promoting guitar. Well done sir!

  35. mark, December 26, 2012:

    Forgot to mention, your videos are also very well done. Easy to understand. Thank you :)

  36. Matthew Warnock, December 26, 2012:

    Thanks Mark, glad you are digging the site and the videos!

  37. Julian, January 5, 2013:

    Hi Matt,

    You mention above that a version of this brilliant app will be developed for PC desktop. Is this still the plan and, if so, when do you think it will be available?

  38. Matthew Warnock, January 6, 2013:

    Hi Julian, it is in development and should be out before mid 2013 as we have a few new apps coming out before that and then we can work on it further. Cheers

  39. Lou Minn, April 7, 2013:

    Hi Matt,
    I downloaded your 251 app from Apple when it was initially released and I love it. It’s great to have your chops available when thinking of new and interesting chord combinations. If there is a small downside, it’s that I’m an older cat and my eyesight isn’t what it used to be. But thats a minor point. Thanks for sharing your expertise with the ‘amateurs’ among us.

  40. Matt Warnock, April 7, 2013:

    Thanks Lou, glad you are digging the App! We have a Jazz Guitar Scale Resource and Practice Tool App coming out in a week or so. The fretboard is a bit bigger on this one so should help if you want to check it out when it’s released. Thanks again!

  41. Jens Valle, June 19, 2013:

    I just purchased a new Samsung Galaxy 4 and am sadly not able to download your app on my phone. When will it be available? Thanks

  42. Matt Warnock, June 19, 2013:

    Hi Jens, I use it on my Samsung S3, so I asked the developer to see if we can make it available for the S4 shortly. Cheers.

  43. David, September 26, 2013:

    Hello Matt. I’ve been using the 251 Android app for a while now and I thought I would give you some feedback. The actual inversions and the voice leading are excellent, thank you. However on the Android platform the app seems very limited – the volume seems very low, even when the device volume is up full. Also, the sounds are the worst quality midi, and there is no rhythm accompaniment to speak of. At least having some kind of basic drum track would make this far more interesting to use. Another constructive criticism, if you don’t mind – when one returns to the previous page in the program to select another progression, the software takes time to recreate the progression – why does it not retain the entire exercise, so that one can easily switch back and forth? The same applies to changes in the metronome speed, it seems to need to start up all over again, and I personally find this frustrating and time consuming. It also interrupts my flow. Please forgive these comments, they are meant as constructive criticism, and I hope they will help in the development of what could be a truly invaluable tool to the practising jazz guitarist.
    Thank you for reading this and please keep up the good work ;)

  44. Matt Warnock, September 26, 2013:

    Hi David. Thanks for checking out the app. These are all things that we’re working on with this app and are in line for upcoming updates. After building this app, my first one, we made some real progress with the sound issues that Android had and iPhones had back then. The new update will have samples of my entire fretboard from my Custom Koentopp Guitar, so it will be much improved. Some issues are beyond our control, but we are working to improve all of our apps in response to feedback from customers and our own testing. Thanks again!

  45. Jay, October 2, 2013:

    Hi Matt-

    In this thread you mentioned releasing a desktop (OSx)version of this 251 chord app. Is that still happening and/or is it out yet?


  46. Matt Warnock, October 2, 2013:

    Hey Jay

    It’s still in the works. We’re dealing with IOS7 updates right now, then can get back to those other items.

  47. Jay, October 3, 2013:

    Ok got it Matt, thanks!

  48. Derek, October 9, 2013:

    Hi Matt,
    Have just purchased your 251 android app and think it is great tool. Your description mentions being able to access multiple rythems and chord dictionary. Can you please tell me how access these as there is no indication on my download that they exist.
    Also many thanks for all your excellent articles.

  49. Matt Warnock, October 9, 2013:

    Hey Derek

    The Dictionary is in the main menu, you can see the screen shot in the pic in this article, the first pic.

    Click on the “gear” symbols when the chord charts are up to change the rhythms on the playback.

    Thanks again.

  50. Derek, October 9, 2013:

    Hi Matt,
    Thanks for your quick response, all now sorted.
    Looking forward to the release of the android version of the jazz guitar licks ap.

  51. briancristopher, November 4, 2013:

    What can I say,
    A goldmine of ideas for the price of a couple of beers!
    I still don’t really understand the terminology behind the Drop1 Drop2 concept so I stopped thinking about it and just use these wonderful chordal ideas/voicings/inversions
    in the tunes I play.
    I have to stop and smile sometimes as I start to feel like a real guitarist.
    Well done Matt, it’s a very cool app… best of luck with it.

  52. monk, November 21, 2013:

    lol.. when I saw the title I thought it was all about ii V I’s. Maybe you should add one more chord so people won’t be confused.

  53. monk, November 21, 2013:

    Wait.. it is about ii V I’s. lol. sorry. I get it now. I was thinking “251 chord diagrams” or something. derp

  54. Darrel Wright, September 14, 2014:

    Hi Matt,
    Did I miss something or has this app not come out for the desktop yet? I don’t run a smartphone, just Linux and would love to use this app on that platform. I can run any windows app. Thanks. I like your work!


  55. Matt Warnock, September 14, 2014:

    No desktop version yet Darrel. Hopefully get to it someday soon.

  56. pickitjohn, January 10, 2015:

    Miss your App worked fine on my Evo…

    Will not work with my Samsung Galaxy 4

    you said
    “Hi Jens, I use it on my Samsung S3, so I asked the developer to see if we can make it available for the S4 shortly. Cheers.”
    Thanks pickitjohn

  57. Matt Warnock, January 10, 2015:

    Hi John, yes we’re having trouble with the Play store as the app is listed as working on the S4 and newer phones, but the store says it isn’t. It’s taking a long time to try and fix, but we are working on it with them to sort it out. Thanks.

  58. Dale, February 11, 2015:


    I wanted to download your Android app but, according to Google, it may be able to read and write from and to my social media networks. Why would it need that permission?

  59. Matt Warnock, February 11, 2015:

    Hey, I think that’s just a general thing Google puts in there. Our apps don’t access anything of yours, especially not social networks, so it is fine. The only thing I can think of is if you rate the app, there’s probably an option on the play store to share that rating with your social networks.

  60. Dale, February 17, 2015:

    Thanks, Matt. I’m going to get the app.
