Raw and unpolished
The app lacks quite a number of features, i.e. an eraser or even zoom, the precision is awful: no matter, a finger or the Apple Pencil, the brush gets stuck at some point and won't draw, and when it will, the stroke gets interrupted at the middle of the process; it won't also draw in the center of the mandala itself, only a centimeter away from it. The variety of brushes is poor, the quality of them too. $3 for this? Give me a break, what have you been expecting, guys? Work on the app first, then try to charge people for it. At this point, it's no more than an unfinished school project.
