GREAT APP but why???!!!!

AMAZING APP!!
But...
Why on earth do we have to buy ONE MONTH OR ONE YEAR?! I would MUCH rather pay once, and get all of the VIP stuff. I dont care how much I pay, as long as its not too much, but I SERIOUSLY dont wanna have to pay for every single month or year.
And the monthly and yearly payments right now are RIDICULOUSLY EXPENSIVE!!!
I used to have this app and it didnt cost anything but I didnt have a guitar. So I deleted it. I recently got one and re-downloaded it, but got 100% disappointed when I saw it.
Dont get me wrong, if youre made of money and looking to learn guitar, loose all your iTunes money for it. Its a great app
Just NOT for the ones that dont have all that money.
