### 3/5 — Doesn’t work on new OS

*2021-02-16, version 1.1*

Wasn’t perfect but did a good job but can’t open since the last update on my phone and it doesn’t look like it’s writing updated again

### 1/5 — Meh

*2019-02-22, version 1.1*

No instructions on how to use it.

### 1/5 — Doesn't work on iPhone 5s

*2016-10-06, version 1.0*

Total waste of money with no customer service.  Tried many times and only get the message "Audio sample is too quiet". FRAUD!

### 1/5 — Read the reviews and don't buy this App

*2015-07-04, version 1.0*

Doesn't work with an iPhone and Apple Music.  How did this crApp get listed in the App Store?

Shoulda read the reviews first.  Hope you do...

### 1/5 — Absolute waste

*2015-05-05, version 1.0*

Has yet to correctly identify the key of any of my ITune or Spotify songs.  You are better off guessing.  Run fast from this one.

### 5/5 — Serves my needs well

*2015-04-20, version 1.0*

I purchased this to identify keys from songs on my spotify playlist.  Since I'm a beginning guitar player, I can then use a capo to play in easier keys if necessary. I use my iPad to play the songs and my iPhone to identify the keys.  I've been using the "rough" mode and it has identified every song I've tried very well after about 30 seconds of playtime.  I'm very have with the $1.99 purchase and the app saves me a lot of time.

### 3/5 — Good algorithm, bad user interface

*2014-08-14, version 1.0*

App includes a few great algorithms for finding the key of a song. I like how they show the correlations with several key options. These are some tried and true methods for key determination. However, I feel like the UI is lacking and the feature set is limited. 

1). You can't change inputs. The app only works through the microphone. You can't find the key of songs in your iTunes library. 

2). The activation of the listen button is clunky. It's hard to tell exactly what the app is doing at the time. 

3). It would be very interesting to have an option use the key finder with all the algorithms at once and use their correlations to weight their top two keys. That way you could get a consensus of the algorithms and possibly decrease error. 

It's an interesting app but limited in its ability and usefulness. A lot more work needs to be done before I could call it a powerful tool.

### 1/5 — Piece of crap

*2014-07-04, version 1.0*

This app will not open! Tried to contact developer but their site only sells crappy software and apps with no way of contacting them for assistance, clearly this is a farce and is only here to sucker people out of money a $1.99 at a time, DO NOT PURCHASE THIS APP UNDER ANY CIRCUMSTANCE! You will be disappointed.

### 1/5 — Waste of money!!

*2014-04-21, version 1.0*

I purchased this app because I need an app to help me pick out the key in a specific song stored in my iPhone. You can't play the song on the phone and have this app listen to it at the same time. What's the point of providing an app that will help you find the song key if you any play the song from the same device?!? Waste of money! I want my $1.99 back!!!

### 3/5 — App is great , but it won't open on iPad

*2014-01-01, version 1.0*

The app is great but it won't open on my iPad, just my iPhone...
