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.

Just downloaded. Aside from the consent part, I just work around it by opening settings and then immediately switching back. Really fixed the issue I had with songs

I realize free versions of apps have to shove ads in your face in order to keep them free, but I downloaded the app and was immediately assaulted with “We want to shove ads in your face.” Against my better judgment, I clicked “I consent,” but that’s not good enough. Now it wants me to go in and change the settings on my phone to give access to my data so it can customize the ads it’s going to shove in my face. Now again, I’m not naive. I get how ad tracking works. But this is a key finder app. Sure, push some ads at me to keep it free, but I’m not giving you access to my data.

I deleted before even using it.

This app DOES EXACTLY WHAT it says it will do. Every time but even faster now. I am a serious hip hop artist and my engineer already has skills exceptional enough to kind the key to a beat for auto tune in under 5mins....this app finds the key in 1mins or faster. I don’t understand how it has basically no reviews and a 2.3 star rating....should be a 5 star rating!!!! GREAT DEVELOPMENT.
