iKeySig is a musical key signature reference tool that displays all of the relevant information for each key including the key signature, the notes of the scale on a piano keyboard and each of the chords of the key for all of the possible keys. iKeySig is a simple no frills quick reference that will appeal to professional, student and hobbyist musicians.
iKeySig is a great teaching and learning tool. It visually displays the notes and chords in such a way that the user can gain an understanding of how music works. Once you can relate the major minor chords of one key, you can use that same knowledge in any key.

Great layout Needs Minors!!
Great layout Needs Minors... The only thing to make this app perfect is the ability to open a Major key signature which it does then display it's relative minor which it does... Which u should be able to "TAP" as a link to the relative minor display:) that would make it perfect. Keep everything the same! Add minors with links to majors an VESA verse! Please.
Other then that great product will recommend to students when minors are added:)
Good app but wrong info
Very good app. Esp for a beginner trying to remember all the scales. Should have minor scales included and relatives to make it a complete app. Also I noticed an error in the Bb major scale. First chord (Bb) says its Bb-D-G. Actually it's Bb-D-F
Some proof reading needs to be done
No minor keys?
Please include minor keys on a future update not just majors.
With Family Sharing set up, up to six family members can use this app.
