Anime Art Studio alternatives

The only animation app that i can use in a production pipeline seriously. For an ipad pro user needing, sketching, inking, colorising on a stack of layers, this is the ideal solution. The ability to import image sequence or voice-over on top of the timeline is definetly a must ! The vector format support makes it very powerfull too. I wish it could had a vector image sequence export as well ( maybe in the future?) Also the pencil behavior could be improved with a custom pressure curve to get more natural results. Can't wait for the next updates
