First post - Why should I buy this app?

Hi!
Have read a couple of posts.
Seems that this app has a lot of potential but is far from being mature enough to be considered as usefull, isn't it?
No pickup measure, just two voices, a lot of work and time just to delete a measure... So much limitations, so much feature requests unanswered...
Looks like working with this app turns out to be very frustrating quickly ? Isn't this app just "teaser" to get users to migrate to the desktop application to really be able to work seriously?
I just hope I'm wrong all the way so, tell me why should I buy this app to give it a try?
And what if I'm not happy with it? Will I have my money back?
Thanks for your help.
