Very good but not great

I love doing the color books so I had to try this. All you need is your finger...good.
You need a very narrow pointed finger...not good.
Since most of us do not have pencil shaped fingers to use this creates frustration...not good at all.
Great colors for free and even greater colors for you to purchase...good.
No, you can not use a stylus...not good.
I see the potential of this program and will continue to use it as long as its free, however, will not pay for added frustration when Im seeking a "get away from it all, self indulgent time".
