Best drawing app EVER!!!


This app is so much fun! The procedural pens are what make this app. I really like the Web pen, its awesome!!!! and its great that you can try the pens before buying them!!

Like anything good, you need to invest a little time reading the built in tutorial to understand how to move around menus.

So far I only bought one pen but I think i will eventually buy penception PRO so i can get all the pens.

Deceptive in-app purchases


In order to even gain access to the procedural menu, you have to pay 0.99. This is rather deceptive, as it implies you get access to all the procedural brushes. But you don't - you just get one, and have to pay individually for all the rest. A waste of my 99 cents. Avoid - there are other apps that have these sorts of brushes, and don't trick you with the in-app purchases.

Too Many Pay Walls

Mystery Bot

Very deceptive! Stop making it about the money dev. Selling us on cool brushes and features that we can't do much with? WHY MAKE A FREE VERSION? Why not make one app? You seem to be confused on how an actual person uses an app. Can the UI be any smaller? Lol 2 stars for clean UI art and a decent new user flow. Duck Duck Moose err I mean Penguin?
