I no longer see all the panels, and the notes no longer play or show reliably when the panels are touched. The wonderful relationships between the rows and columns of panels no longer exists. The last update was for iOS 4 over 2 years ago. Will someone help keep this app alive, or will Chroma be the only app remaining that uses Shepard tones to help us understand music in such a creative way? ### 2/5 — Needs another update *2012-12-19, version 1.2* Doesn't work with 3rd generation iPad with OS 6.1. The app opens and seems stable, but it doesn't behave as expected (it zooms in very close and doesn't respond consistently to taps on the screen). Too bad as the concept is very cool. ### 3/5 — Issue on iPad 3 with iOS 6.1 *2012-11-23, version 1.2* This looks like a really good app but having just installed it on and iPad 3 with ios 6.1 I have found it is not working as per the screenshots. I appear to have a display which is zoomed in, I.e. only a few hexagons are visible and running my finger over the display results in changes of tone in the middle of the hexagons, i.e. where there should be no change. I guess the sensing of the finger position is correct but the displayed image is wrong. Looking forward to a fix so I can try this app properly. ### 2/5 — Great, but doesn't work right on new iPad *2012-03-28* Looks like the retina display freaks this app out - please fix? Thanks! ### 3/5 — Doesn't work correctly on new iPad *2012-03-25* This is a very cool app but does not work correctly on the new iPad. ### 5/5 — nifty application *2011-01-27* Sounds fantastic. Shepard Tones are pretty cool. And don't forget to practice your pitch - sing and it will light up the tone you are singing. ### 4/5 — Works perfectly now *2011-01-24* Update fixed the crashes. Now to explore.... ### 5/5 — Great app! *2011-01-24, version 1.2* It did briefly stop working some time after the 4.2 update but now that it doesnt crash on startup it's a great app. Nice sounds and random poking even sounds good! To me at least, thank you for the great app and the update. ### 4/5 — It's great *2011-01-24, version 1.2* It's finally fixed. Working great now. Thanks It's not working at all. It's a great idea that I wish could be expanded on, maybe show different kinds of scales, suggest chords for progressions that are less typical. Again this was a 4 or 5 star app, but at som point it stopped working, not sure when... Maybe when iOS 4.2.1 came out. No keys work at all. ### 1/5 — Closes when opened *2010-12-27, version 1.1* This app opens for about 5seconds then shuts down. Needs a fix! ## Most critical reviews (10 lowest-rated) ### 1/5 — Boring *2014-03-02, version 1.3.0* If you think this is an app when you can harmonize your voice, its not. Its boring and it sounds like church music which to me is not good so deleted it and im never gonna get it back! ### 1/5 — Update *2013-01-04* Broken. Needs update. ### 1/5 — New iPad update *2012-07-08* Was recommended this app, but doesn't work at all on the new iPad. Please fix, thanks! ### 1/5 — Does not work on ipad3 *2012-04-05* Please update! ### 1/5 — Just installed and... *2011-01-22, version 1.1* It crashes as soon as it is launched, for that reason I can't rate higher than 1 star. ### 1/5 — Crashes *2011-01-20, version 1.1* This crashes on startup ### 1/5 — What? *2011-01-15* This app doesn't work. I open the app, it shows me the screen for about 3 seconds and then shuts down. Never got to use it. Interesting idea, just wish I could actually see what it can do. ### 1/5 — Ummm *2011-01-05, version 1.1* Crashes on start up. ### 1/5 — Simply does not work *2011-01-05, version 1.1* It closes as soon as you open the app. Boourns! ### 1/5 — Crashes immediately. *2011-01-01, version 1.1* iOS 4.2.1 ## Most praised reviews (10 highest-rated) ### 5/5 — Please update this app! *2017-09-15* My 6 month old loves it, but Apple is saying iOS 11 won't run it! ### 5/5 — 😍😍😍😍 *2014-04-18* FIFTH HARMONY,!! ### 5/5 — AWESOME *2012-09-12, version 1.2* Best app ever ### 5/5 — Wonderful *2012-06-01, version 1.2* Two things I would like to see for this wonderful app. If it had a first page with the 'how to' on it would make searching for instructions easier to find and refer to. The second thing would be the ability to turn off the 'pitch seeking' display if you wanted to. I find it quite distracting whilst sitting and contemplating patterns and moves. To be able to start or stop this feature on the home/first page would be a great help. Thanks so much for building this app. I think it's wonderful! ### 5/5 — Fun *2012-04-22, version 1.2* Fixed! I encourage you all to try it! ### 5/5 — Simple and Brilliant *2012-03-30, version 1.2* This is brilliant in its simplicity and execution, so much fun. ### 5/5 — Unrecognized genius *2011-12-17* This app is an incredibly clever representation of chord structure, truly blown away by the organization by shape and color of western music theory. If one is a true musician it is easy to see how awesome and beautiful this program can be. I originally downloaded this as entertainment for my infant daughter but since have realized the full potential of this triumphant system :) ### 5/5 — Delightful *2011-10-28, version 1.2* A lovely app for exploring musical harmony. ### 5/5 — Great Innovation *2011-08-27, version 1.2* Novel concept, good solid engineering. And free! Thankyou! Who is giving this one star?! Some intelligent and creative individual has gone to great trouble to offer you something extra-ordinary, and for free. What is so wrong with your life that you have to leave your ugly little mark of negativity? One-star people. Five for the app. ### 5/5 — working perfectly now *2011-01-27* this app is so simple, but so mesmerizing. i never thought i'd have so much fun with it. everything works perfectly with the update. the only thing that i would change is if the note letter showed up on all spaces where the same note can be played. if you touch C, it would be nice if the other C spaces showed the letter C as well. thanks! --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
