Almost seems like it defaults to that. ### 3/5 — Good but needs some work *2017-01-14, version 2.2* The app works well for instrumentals. If there are voacls, it will throw off the app. It's good but of course could use work. ### 1/5 — I want a Refund!!! *2015-02-19, version 2.2* This app has not gotten not one key right yet!!! ### 1/5 — Garbage App *2015-02-03, version 2.2* Says Mozart's 41st Symphony in C is in B minor. ### 1/5 — Needs an update *2014-08-07, version 2.1* The app will not recognize the keys that songs are in when using the mic function. Also, it is unable to actually play / analyze the songs in my library. I keep receiving an error message that says the song is not actually in my library. ### 1/5 — Key+ *2014-07-25, version 2.1* This app doesn't work, always shows B Minor no matter the key. ### 1/5 — Working 50% *2013-10-23, version 2.0* Won't analyze song already in the iphone And when analyzing through mic it's not accurate ### 3/5 — Not always accurate *2013-07-09, version 2.0* It works quickly but canon in D is not in A major.. ### 4/5 — Suggesting an addition *2013-01-08, version 2.0* Nice app. Would be nice if it would analyze what was playing in another music app. ## Most critical reviews (10 lowest-rated) ### 1/5 — Terrible *2019-02-23, version 2.2* After paying 2 dollars for this app, every time it listens to anything it crashes immediately after. Waste of money and time for an app that does nothing. ### 1/5 — Trash *2019-02-16, version 2.2* Worst 2 bucks ever spent! Dont get it wont even read anything, dont waste your time or money ### 1/5 — SCAM *2019-02-02, version 2.2* Nice try Billy McFarland, maybe try making an app that doesn’t crash immediately after analyzing a song. @itunes can we delete this trash from the App Store. Thank You ### 1/5 — Crashes Galore *2019-01-17, version 2.2* For a paid app, I would expect maintenance to be regularly updated. This app not only had views that say that it isn’t accurate, but it crashes immediately after listening for me. All in all, this is the worst 2 dollars I’ve ever spent. ### 1/5 — Doesnt work *2019-01-15, version 2.2* Closes every time I try to find the key ### 1/5 — Crashes every time. *2018-12-01, version 2.2* Easy to use... 1 Star. After listening for 15, 30 seconds - counter increasing to 100%, app goes blank. Never displays a key... just returns to the screen of icons. ### 1/5 — Doesn’t work *2018-08-12, version 2.2* Very very inaccurate, waste of money ### 1/5 — Complete waste of money *2018-01-13, version 2.2* Doesn’t matter what song you try, everything is in Bm. Gee! Who knew?? Certainly simplifies things :( ### 1/5 — Terrible *2017-05-16, version 2.2* Spits out random results ### 1/5 — Inaccurate *2015-07-20, version 2.2* Hasn't gotten any keys right. ## Most praised reviews (10 highest-rated) ### 5/5 — Bugs *2022-09-30, version 2.4* I love this application but I couldn’t open it today. Seems there are some bugs that need to be fixed !! ### 5/5 — Nice *2018-09-15, version 2.2* I am a Audio engineer and every sense I ran across this app it have been a time saver for me for when I am recoding singers who need the auto tune in the right key. This app help me with the key that the song are in so I can set the key and note scale so the auto tune can correct the singer notes. This help me with hearing the key without using it but I still use this app to make sure. ### 5/5 — Great for singers *2017-08-26, version 2.2* Sing into the microphone until the percentage at the bottom of the screen gets to 100%. And up pops the key you're singing in. ### 5/5 — Very good !!!!! *2014-04-07, version 2.0* Look if you use mixed in key and you need to figure out what that other person you are coming off of is playing , than this will tell you the key they are in ,chart it then,and your set .I would say with a 90% or better accuracy. That's if they don't already have MNK. ### 5/5 — I love this app but... *2013-12-07, version 2.0* I recently got a new phone with a bigger screen and it doesn't fit, so it would be nice if I could be universal for all iphone devices. ### 5/5 — great for the vinyl dj *2013-08-24, version 2.0* easy to use, works great, been using this to start cataloging keys of my record collection ### 5/5 — PERFECT! *2013-06-14, version 2.0* This app is perfect for band practice to quickly figure out what key we're playing a song in- exactly what i needed. I give it 6 flags. More flags, more fun. ### 5/5 — Best $2 spent in the App Store! *2013-04-14, version 2.0* Works exactly as advertised and better than I figured it would. Wish it showed the notes in the key though but can't complain. ### 5/5 — Amazing *2013-02-04, version 2.0* This was exactly what I was looking for, great for anyone who uses a looper or plays along with other music to find the key and know what scale to play. Excellent ### 4/5 — I like it *2015-04-09, version 2.2* Works well, setting sample rate at a longer time helps. It's not perfect but mostly correct, some songs are very complex and hard for software but most popular music songs work, I use it when playing harmonica! --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
