I just downloaded an Ipad app; Songcatcher -- corecloud.com/express. The spec sounded good, it is made in Sweden. It is a free App. You can sing or hum a single line into the Ipad and it write a single line score. I have some church friends who have put their songs together in their heads; they want me to place it on paper. Chords needed are not a problem.
Question:

I opened the program in my Ipad and it asked for me to sign in. BUT it asked me for my I.D. number I use with Itunes. I use this number to purchase.

DOES THIS SOUND LIKE AN AREA,APP I SHOULD AVOID?

Thanks you,
John C.
