## What is Song Key Finder?

Have you ever been listening to a song, or have a friend playing some chords and want to know what key the song is in?  This app could help.

This little helper can be used to identify the key a song is in via several methods:

 * Analysing live music via the devices's microphone 
 * Analysing a local audio file on the device
 * A set of user-entered chords 

All analysis is performed locally on the device, so doesn't use your mobile data allowance.

The results of a scan can then be saved to be referred to later if required.  

If there is a song that changes key part way through, on the song detail page you can enter the chords, or analyse via the microphone while you play that part of the song.

## Key features

- Analyze live music via microphone
- Analyze local audio files
- Input chords manually
- Save scan results
- Support for songs with key changes

## Pricing and in-app purchases

Base price: Free.

### 5/5 — It works

*2024-12-25, version 1.20.202*

This app works perfectly. Not sure why it has bad reviews.

### 1/5 — Don’t waste your money

*2023-07-15, version 1.15.166*

There are FREE websites that do more than this app.

### 2/5 — Not reliable

*2023-07-09, version 1.15.166*

I’ve scanned 30 violin concertos and classics pieces. It got 3 of them correct 😬. At least I don’t have ads on the screen when it gets them wrong that’s what counts.

### 1/5 — Not sure why this is happening…

*2022-08-24, version 1.7.287*

Every song I play come up as key of F, F minor, or F #. I’m not a musician but I played songs in Spotify that are marked as being in different keys and the songs ALWAYS come up in the key of F. Tried about twenty songs… very disappointed.

### 3/5 — Question

*2022-08-01, version 1.7.287*

I already was charged and paid for no ads
Had to reload down from cloud and it wants to charge me again?

### 1/5 — How are these apps available on the store

*2022-07-24, version 1.7.287*

It’s a note finding app. You’re all out of your minds if you think I’m giving you any access to tracking my phone/data for “better ads”. Stop it. You and I both know you’re not making a note finding app. This is a blatant data scraping app. 
What an insult. Disgusting practice. 
You shouldn’t be allowed on any App Store.

### 3/5 — Files problem

*2022-04-12, version 1.7.287*

I like the app but certain files won’t open… I’ve tried several things to get the file to open but it won’t any tips

### 1/5 — Don’t get

*2021-09-02, version 1.7.287*

Immediately tries to acquire all your data and cookies. Also you have to pay eventually just save yourself and find something else

### 1/5 — Not good

*2021-08-28, version 1.7.287*

It don’t even give the right key of a song, it’s always incorrect. I searched every song I entered and the key wasn’t right. I look up a song it will say g minor, then I will put song into app then it says c major. This is a bad app!!!!

### 5/5 — Exact result

*2021-05-26, version 1.7.287*

Thank you
