It's very frustrating; the predatory knockoffs have aggressive SEO, so people casually googling for "wigglypaint" tend to find them first, and the users mislead in this way share them with others, reinforcing the problem. It hurts my heart to see artists exploited and charged money for an outdated copy of a tool that should be free. :(

I just checked my mail and found this reply to my review from the one that put wiggly paint on the AppStore: "Hi, WigglyPaint is not a web wrapper or a cross-platform hybrid — it is hand-crafted in SwiftUI with Metal-accelerated drawing. That means instant launch, 120 Hz ProMotion scrolling, and the right feel on every Apple device." I got my refund without issues btw.
The price also seems to have gone up almost double the price and the ranking too..
