It’s broken. ### 1/5 — Doesn’t do any analysis *2021-04-23, version 2.1.9* It just dorsn’t work. Prints “error”. Russian song «Вижу», artist «Магелланово облако» ### 1/5 — Doesn't work *2015-11-02* Dear Casio: I recently paid for and downloaded the Chordana App. I would like a refund. This app does not work and was very expensive. It won't analyze any songs I have- the songs are downloaded and are DRM free and I'm using the correct operating system. I read your instructions thoroughly and the app still doesn't work on ANY song. I am very disappointed as I trusted the Casio brand. ### 1/5 — Useless for iTunes Songs *2014-09-27* Just purchased this app and I get an error message "cannot be used" for EVERY one of my downloaded iTunes songs that I select. Fix this or refund my money!!! ### 1/5 — Crashes! *2014-02-16* This app simply does not work! If you choose a song from your iTunes library it crashes. How could this still be available for purchase when it STILL has these issues?! ### 1/5 — Crashes 100% of time *2014-01-05* This really is a zero rating: you try anything but the demo tunes and it crashes every time. Basically, you are paying $10 for a picture of an icon. ### 1/5 — bad *2013-12-19* waste of money ### 1/5 — Horrible *2013-11-07* This app is a great concept but the execution is miserable. Crashes and when it doesn't it's getting the chords so off it's unforgivable. I definitely want my money back. ### 1/5 — dont bother *2013-11-04, version 1.0.1* does poor analysis on most basic songs. disappointed i wasted $10 on this. ### 1/5 — Crashes every time *2013-11-03, version 1.0.1* Great idea, but I have not been able to use it. It crashes every time I try to analyse a song. ## Most praised reviews (8 highest-rated) ### 5/5 — Very cool *2024-09-07, version 2.1.10* Thanks for great stuff✌️ ### 5/5 — Great update *2020-06-03* I’m so happy. The latest update has put it back to brilliance 😁 all perfect again 👍🏻👍🏻😁😁👍🏻👍🏻 ### 4/5 — Much Better *2014-08-08* With the latest update you can now export the charts that Chordana creates. The chord detection is pretty remarkable technology and although it is not 100% accurate it is enough to help you out get you in the ballpark. Now you can take the chart, email it to yourself or print it out. ### 3/5 — Needs work *2014-08-16* The software itself is kind of magical. The ability to analyze music and discern chords and melody and create a chart is impressive. But the interface isn’t very intuitive, and there seem to be some fundamental issues. On my iPhone, Chordana recognized my iTunes songs and translated them. On my iPad, it wouldn’t work with any of my content and returned an error. Support seems to be nonexistent so I have no idea how to fix it. ### 2/5 — FILES support needed *2020-06-04* Please add apple FILES support ### 2/5 — App needs work *2013-11-22* This app gets the general key of the song correct, but gets most of the chords wrong. Additionally it has never synced to the right tempo to follow along with the song. It's a cool concept, wish it worked. It's not hard to learn a song by ear once you find the key of the song, just wanted to test this app out, and it disappointed. ### 2/5 — 25% chance of working with songs from iTunes *2013-11-06* Great app when it works, but most of the time it simply crashes. ### 2/5 — Great Idea... But consistently crashes on my iPad 3! *2013-11-02* Hello— Just wanted to chime in and say I was quite excited to read that such an app exists at all in the iOS store. I downloaded the app to my iPad 3 and, while Chordana was able to analyze the demo songs just fine, the app crashed whenever I import a song from iTunes. Can this problem be fixed, please? I am running iOS 7.0.2. The crash occurs even after I cancelled my background apps and rebooted my iPad. Thank you! While I'm here, I would love to see an update which allows an MP3 file from any app to be opened in Chordana. That would be a very handy feature. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/). User reviews are verbatim App Store reviews.
