Harmonica (Harp) players best friend.

It can be challenging for Harp Players to find a key to play. Song Key Finder narrows the key down quickly or gives options for others. Missed a few times but overall it was less searching and more playing. THANKS

App is great , but it wont open on iPad

The app is great but it wont open on my iPad, just my iPhone...

Waste of money!!

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 cant play the song on the phone and have this app listen to it at the same time. Whats 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!!!

Piece of crap

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.

Good algorithm, bad user interface

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 cant change inputs. The app only works through the microphone. You cant find the key of songs in your iTunes library. 2). The activation of the listen button is clunky. Its 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. Its 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.

Serves my needs well

I purchased this to identify keys from songs on my spotify playlist. Since Im 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. Ive been using the "rough" mode and it has identified every song Ive tried very well after about 30 seconds of playtime. Im very have with the $1.99 purchase and the app saves me a lot of time.

Absolute waste

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.
