I KEEP READING THIS APP IS RIPPED OFF FROM OTHER APPS?

As I stated I keep reading people saying that this App is a ripoff of other Apps? Hey you bought it so three stars just for that and by the way EVERYONE the new GarageBand, they just added this into their App but times x10!!! So I dont see this app being around for long! Why use this App when you have everything included with so many other Apps!!! But whatever App you use, just keep writing music! I miss 4 track cassette, all I do is update and search for Apps taking away from the time I actually have to spend writing music. Im sure allot of people can relate to that? These Apps were supposed to make it easier???
ANY SIMPLE RECORDING APP (WITH A METRONOME) A SHEET OF PAPER AND A PEN!!!
