I was of the same mind set, but once I realized that the complete set is $7.99 I was fine with the purchase option. Mind I was only fine with this after experiencing the fluidity and accuracy of the pen.
So if you are comfortable paying $9.99 for a app upfront, I highly suggest you download Paper, and purchase the "The Complete Set" for just $7.99.
<infomercial voice> That's a savings of $2!!! <infomercial voice>
You're 100% correct and I was not aware of that either. Every article I read did not mention that point. They made it seem once you buy everything it was like $50 or something.
Since there was such and outcry each direction I had to download since it was FREE anyway. I did love the flow compared to other drawing programs. I wish there was a erase page option in addition to the wheel, but small issue.
Then I realized the whole program was $8 so I got it. Very nice and enjoy drawing with it compared to other programs. Need to play with my new brush stylus I backed on Kickstarter, have not used it yet, but it is a capacitive paint brush, should be nice for this watercolor program.
Going on vacation in a couple weeks, will play with it more on the beach in Oahu.
Got my Polarized glasses ready to see how it helps on the beach horizontally. (funny how it wipes out the screen when vertical.
